(E). The mass of a star, after passing through the red giant stage, will determine whether it compresses itself into a white dwarf, a neutron star, or a black hole.
Answer -
60). D is the best choice -- Mass determines whether a star, after passing through the red giant stage, will compress itself into a white dwarf, a neutron star, or a black hole.
(Read the sentence without the words stated in orange color.)
A - incorrect -- dangling modifier...(depending on mass)
B - incorrect -- "its" refers to the red giant stage's mass.
C - incorrect -- star's mass will determine if it compress itself...again here it refers to mass rather than star.
E - incorrect -- Mass of start after passing....it is star that is passing and not the mass.

D). most people who see it find the acting and cinematography at least as good or even better than those in the original
E). most people seeing the film find the acting and cinematography at least as good as or even better than those of the original's
Answers -
43). The correct answer is D -- It correctly uses the pronoun "who" to refer to a girl and her family. Additionally, the phrase "by a gentile Dutch couple" is placed immediately after "who were hidden" to clarify the meaning. Finally, the ambiguous pronoun issue is avoided altogether.
A - incorrect -- The original sentence uses the relative pronoun "that" where "who" is preferred because the antecedent is a group of people. Also, the prepositional phrase "by a gentile Dutch couple" is placed in such a way as to suggest that the occupation was carried out by the couple. Finally, the pronoun "they" is ambiguous – it could refer to the family or to the couple.
B - incorrect -- This choice incorrectly uses the relative pronoun "that" to refer to a group of people. Additionally, the pronoun "they" is ambiguous - it could refer to the family or to the couple.
C - incorrect -- The use of the object pronoun "whom" makes "a girl and her family" the object of the clause "a gentile Dutch couple hid;" however "a girl and her family" are the subject of the next clause "were eventually discovered." This is a mismatch.
E - incorrect -- The pronoun "they" is ambiguous - it could refer to the family or to the couple.
44). The correct answer is C -- This choice correctly replaces "it" with "film", adds the missing "as", and makes clear that the acting and cinematography in the sequel are compared to the acting and cinematography in the original.
A - incorrect -- First, the pronoun "it" is used to refer to the film, but the film has not been mentioned in the sentence. Instead "the sequel's poor critical reception" has been mentioned. This is not the same as the film, so the pronoun "it" has no grammatical antecedent and must be changed.
Second, the phrase "at least as good or even better than" is incomplete: there should be another "as" after "good".
Third, the cinematography and acting are being compared to the "original". What is meant here is that the cinematography and acting in the sequel are as good as the cinematography and acting in the original. This must be changed.
B - incorrect -- The pronoun "it" has no grammatical antecedent and the phrase "at least as good or even better" is missing the second "as" after "good."
D - incorrect -- The pronoun "it" has no grammatical antecedent and the phrase "at least as good or even better" is missing the second "as" after "good."
E - incorrect -- This choice introduces the possessive redundancy "those of the original's." One could say either "those of the original" or "the original's", but using both is redundant.

43). The correct answer is D -- It correctly uses the pronoun "who" to refer to a girl and her family. Additionally, the phrase "by a gentile Dutch couple" is placed immediately after "who were hidden" to clarify the meaning. Finally, the ambiguous pronoun issue is avoided altogether.
A - incorrect -- The original sentence uses the relative pronoun "that" where "who" is preferred because the antecedent is a group of people. Also, the prepositional phrase "by a gentile Dutch couple" is placed in such a way as to suggest that the occupation was carried out by the couple. Finally, the pronoun "they" is ambiguous – it could refer to the family or to the couple.
B - incorrect -- This choice incorrectly uses the relative pronoun "that" to refer to a group of people. Additionally, the pronoun "they" is ambiguous - it could refer to the family or to the couple.
C - incorrect -- The use of the object pronoun "whom" makes "a girl and her family" the object of the clause "a gentile Dutch couple hid;" however "a girl and her family" are the subject of the next clause "were eventually discovered." This is a mismatch.
E - incorrect -- The pronoun "they" is ambiguous - it could refer to the family or to the couple.
44). The correct answer is C -- This choice correctly replaces "it" with "film", adds the missing "as", and makes clear that the acting and cinematography in the sequel are compared to the acting and cinematography in the original.
A - incorrect -- First, the pronoun "it" is used to refer to the film, but the film has not been mentioned in the sentence. Instead "the sequel's poor critical reception" has been mentioned. This is not the same as the film, so the pronoun "it" has no grammatical antecedent and must be changed.
Second, the phrase "at least as good or even better than" is incomplete: there should be another "as" after "good".
Third, the cinematography and acting are being compared to the "original". What is meant here is that the cinematography and acting in the sequel are as good as the cinematography and acting in the original. This must be changed.
B - incorrect -- The pronoun "it" has no grammatical antecedent and the phrase "at least as good or even better" is missing the second "as" after "good."
D - incorrect -- The pronoun "it" has no grammatical antecedent and the phrase "at least as good or even better" is missing the second "as" after "good."
E - incorrect -- This choice introduces the possessive redundancy "those of the original's." One could say either "those of the original" or "the original's", but using both is redundant.

(D) not to think or assess, but doing one's own work
(E) neither to think about one's own work nor to assess it, it is always simply doing it
Answers -
41). C is the best choice -- "Mozart" is correctly placed as the subject of the opening modifier "starting at age four." Additionally, the phrase "his own" clarifies that the musical talents in question are those of the subject, Mozart.
A - incorrect -- The original sentence begins with a modifier ("starting at age four") that describes Mozart. Yet, the subject of the main clause is Mozart's father. We need to find a choice that make Mozart himself the subject. Moreover, the pronoun "him" has no grammatical antecedent, since it is meant to refer to Mozart despite the fact that Mozart is not actually present in the sentence (we have "Mozart's father" instead). Finally, the pronoun "his" is somewhat ambiguous: does it refer to Mozart (who, again, is not in the sentence) or to his father?
B -- incorrect -- "Mozart's father" serves illogically as the subject of the opening modifier "starting at age four." Additionally, the pronoun "his" is ambiguous in that it could refer to the boy or the father.
D -- incorrect -- This choice incorrectly uses the verb "was," which does not match the ongoing nature of the modifier "starting at age four." Additionally, the pronoun "his" is ambiguous in that it could refer to Mozart or his father.
E -- incorrect -- "Mozart's father" serves illogically as the subject of the opening modifier "starting at age four." Additionally, the pronoun "him" has no grammatical antecedent, since it is meant to refer to Mozart despite the fact that Mozart is not actually present in the sentence (we have "Mozart's father" instead).
42). The correct answer is A - maintains parallelism - thinking, assessing, doing
D, E - incorrect - violates parallelism -- think, assess, doing are not parallel
C - incorrect - violates parallelism -- thinking, assessing and to do it are not parallel.
B - incorrect -- the antidote to envy is to work always -- changes the meaning of the original sentence.

B, C -- incorrect -- incorrectly replaces "as" with "like". Furthermore, in
C, "when he had established a mosque" distorts the intended meaning by stating that the first action was completed before the second was begun.
D -- incorrect -- "had established... using" states that Mohammed had already performed the actions before capturing Athens; In addition D includes the unidiomatic construction "using x to be y."
E -- incorrect -- "establishing" and "using" modify Athens, thus
producing an absurd statement.

"ordered", producing the grammatical and idiomatic sequence - x ordered y to do z.
A, B -- incorrect -- "should prepare" in A and "would do" in B produce ungrammatical sequences - x ordered y should/ would do z.

Answers -
36). D is the correct answer -- uses parallel verb forms to complete the construction "have been able to put... and remain". The logical comparison here is between large steel plants and small mills.
A, B,C -- incorrect -- illogically contrast large steel plants with [the] processing [of] steel scrap. Further, in choices B and C remaining is
not parallel with put; consequently, it is not clear exactly what is remaining economically viable.
E -- incorrect -- remained is not parallel with put.
37). Correct choice is C -- produces a sentence in which pronoun "it" refers clearly and logically to the noun "condition".
A, B -- incorrect -- the phrase "indicate that there . is one" does not grammatically fit with "when it is not" because it has no referent.
B, D -- incorrect -- are imprecise in saying that a test will fail to detect
when a condition is present, since the issue is the presence and not the timing of the condition. Further, "its" presence in D leaves the "it" in "when it is not" without a logical referent: it must refer to condition, not presence.
E -- incorrect -- repeats the error stated above ; also, "the presence ... when it is there" is imprecise and redundant.

B). Though Saturn's main rings may appear smooth and continuous when viewed from a distance, they are in fact composed of thousands of separate icy ringlets when viewed up close.
C). Saturn's main rings, when viewed from a distance, may appear to be smooth and continuous, though when viewed up close they are in fact composed of thousands of separate icy ringlets.
D). When viewed from a distance, Saturn's main rings may appear smooth and continuous, but closer viewing reveals them to be composed of thousands of separate icy ringlets.

B). had been built at so high of an altitude that it often makes modern-day tourists from lower elevations sick from oxygen deprivation
C). was built at a high enough altitude that modern day tourists from lower elevations often become sick with oxygen deprivation when visiting the city
D). was built at such a high altitude that modern-day tourists from lower elevations often become sick from oxygen deprivation when visiting the city
E). was built at so high of an altitude that it often makes modern-day tourists from lower elevations sick from oxygen deprivation
Answer -
34). D is the correct answer - This sentence checks the clarity of meaning and modifiers. This choice replaces "though" with "when" and shortens "appear to be" to "appear." Further, its use of the phrase "closer viewing reveals" clearly indicates that the close viewing only reveals (not causes) the composition of the rings.
A - incorrect - The original sentence introduces the main clause with "though viewed from a distance", which sets up the expectation of a contradiction that never materializes. For example, "Though sleepy, the child stayed awake" is correct, whereas "Though sleepy, the child may have eaten soup" is not.
Also, "when viewed up close" is placed in such a way as to illogically suggest that the rings are composed of icy ringlets as a result of being viewed up close.
Finally, "appear to be" is redundant.
B - This choice incorrectly introduces the main clause with "though." Additionally, the placement of "when viewed up close" illogically suggests that the rings are composed of icy ringlets as a result of being viewed up close.
C - This choice incorrectly uses the redundant phrase "appears to be." Additionally, the use and placement of the words "when viewed up close, they are . . ." illogically suggests that the rings are composed of icy ringlets as a result of being viewed up close.
E - This choice incorrectly introduces the main clause with "though." Additionally, the placement of "if viewed up close" illogically suggests that the rings are composed of icy ringlets as a result of being viewed up close.
A). Though viewed from a distance, Saturn's main rings may appear to be smooth and continuous, they are in fact composed of thousands of separate icy ringlets when viewed up close.
B). Though Saturn's main rings may appear smooth and continuous when viewed from a distance, they are in fact composed of thousands of separate icy ringlets when viewed up close.

B). had been built at so high of an altitude that it often makes modern-day tourists from lower elevations sick from oxygen deprivation
C). was built at a high enough altitude that modern day tourists from lower elevations often become sick with oxygen deprivation when visiting the city

C - This choice incorrectly uses the redundant phrase "appears to be." Additionally, the use and placement of the words "when viewed up close, they are . . ." illogically suggests that the rings are composed of icy ringlets as a result of being viewed up close.
E - This choice incorrectly introduces the main clause with "though." Additionally, the placement of "if viewed up close" illogically suggests that the rings are composed of icy ringlets as a result of being viewed up close.
35). D is the correct answer - The simple past verb "was" correctly replaces the past perfect verb "had been." The phrase "such a high altitude" replaces "high enough altitude." The sentence is rewritten to avoid ambiguity by removing the pronoun "it." Finally, this choice uses the phrase "sick from" in place of the unidiomatic "sick with."
A - incorrect - First, the past perfect "had been" is unnecessary here because there is only one past event. Second, "high enough" implies that the oxygen deprivation was a goal of the Incas. Third, "it" in this context is ambiguous: is it the altitude or the city that makes tourists sick? Finally, "sick with" is incorrect. It should be "sick from."
B - incorrect - This choice incorrectly uses the past perfect "had been." Additionally, the pronoun "it" is ambiguous in this context and the phrase "so high of an altitude" is awkward.
C - This choice incorrectly uses the phrases "high enough altitude" and "sick with."
E - This choice incorrectly uses the awkward phrase "so high of an altitude." Additionally, the pronoun "it" in this context is ambiguous.

A - Incorrect - sentence begins with the modifier "Famed for his masterful use of irony," which requires a person as its subject. However, in the sentence, "many of Guy de Maupassant's short stories" is the subject. Moreover, the phrase "due to the author slowly revealing" is awkward.
B - incorrect - The pronoun "he" must have a person as its antecedent, yet there is no person in the sentence. Remember that "he" cannot refer to "Guy de Maupassant" here, since the name is part of a possessive phrase: "Guy de Maupassant's short stories". The author himself is not grammatically present in the sentence.
C - incorrect - The opening modifier "famed for using irony in a masterful way" incorrectly modifies "short stories" instead of Guy de Maupassant himself. It also contains the awkward phrase "because of the author slowly revealing."
E - incorrect - This choice incorrectly uses the pronoun "he" without a grammatical antecedent in the sentence.
31). C is the correct choice - The construction "either X or Y" requires parallelism between X and Y. In choice C, both X and Y are parallel infinitive phrases ("to approach . . ." and "to force . . .").
A - incorrect - incorrectly pairs an infinitive ("to approach") with a clause ("that they should...") in the construction "either X or Y." Moreover, the use of "like" in the phrase "to approach mathematics like a creative activity" is incorrect. :"As" should be used instead.
B - While this choice does contain proper parallel structure, it incorrectly uses "like" instead of "as" in the phrase "to approach mathematics like a creative activity".
D - This choice incorrectly pairs a clause ("that they should...") with an infinitive ("to approach") in the construction "either X or Y."
E - While this choice does create a parallel construction, it awkwardly begins the parallel elements with the words "that they" instead of the infinitive "to." Moreover, this choice incorrectly uses "like" instead of "as" in the phrase "to approach mathematics like a creative activity".
A). Famed for his masterful use of irony, many of Guy de Maupassant's short stories have become classics due to the author slowly revealing at the end of each piece a tragic twist of fate.

Answers -
26). Choice E, the best answer, uses the adverbial phrase "more quickly than" to modify the verb phrase "gain weight".
In A, B, and C - "quicker than" is incorrect because an adjective should not be used to modify a verb phrase.
A and B - incorrectly compound that present tense verb with a past tense verb, "associated".
C and D - correctly use "associate", but C follows with the past tense "required" and D with the present perfect "have required". Both C and D incorrectly conclude with the future tense "will gain".
27). E is the best choice.
The use of the phrasing "can heat... enough to affect" in A and E is more idiomatic than the use of the subordinate clause beginning with "that" in B, C, and D.
B - produces an illogical and ungrammatical statement by making "induce" parallel with the verb "heat" rather than with the appropriate form of the verb affect
C - lacks agreement in using the singular pronoun "it" to refer to the plural noun "displays"
D - is faulty because "induces" cannot fit grammatically with any noun in the sentence.
A - incorrectly separates the two infinitives "to affect" and "to induce" with a comma when it should compound them with "and", as does E, the best choice.
28). C is the best choice.
A, B, D - the phrases "on account of" and "because of" are unidiomatic; "because", which appears in C and E, is preferable here since "because" can introduce a complete subordinate clause explaining the reason why the golden crab has not been fished extensively.
B , E - also produce agreement errors by using the plural pronouns "their" and "they" to refer to the singular noun "crab".
D - like A, fails to provide a noun or pronoun to perform the action of living.
C - which uses "because" and "it" as the singular subject of a clause, is the best choice.
29). C is the best answer. Grammatically, the participial phrase beginning delighted must modify the subject of the main clause. Because it is the manager who was delighted, choice C, in which the company manager appears as the subject, is the best answer.
A, B, D, E - create illogical statements by using it, the decision, the staff, and a raise,respectively, as the sentence subject.
A , D , E - Use of the passive voice

24). E is the best choice.
A - Dangling modifier - the introductory clause beginning Based on modifies scholars, the noun that immediately follows it.
In other words, A says that scholars were based on the accounts of various ancient writers.
B - is awkward and imprecise - referent of pronoun "it" is not clear.
C, D - are also wordy and awkward.
Further in D - By the accounts... they used is an unidiomatic and roundabout way of saying that scholars used me accounts.
E - is clear and concise - correctly uses a present participle (or "-ing" verb) to introduce the modifier describing how the scholars worked.
25). E is the correct choice.
A - The subject of the original sentence is "the number of acres", which is singular. The main verb, however, is "have increased", which is plural. We need to find a choice that replaces "have" with "has". Moreover, the phrase "due to" is incorrect in this context. "Due to" is a phrase that must describe a noun. "The fire was due to drought" is correct, but "There was a fire due to drought" is not. When describing a verb phrase, "because of" is preferable: "There was a fire because of drought."
B - The plural verb "have been" does not agree with the singular subject "the number of acres." Additionally, the passive voice "have been increased" is incorrect. Finally, the phrase "due to drought . . ." is unidiomatic since "because of" (not "due to") should be used to modify the verb phrase "have become an ongoing threat."
C - The modifier "which has become an ongoing threat . . ." contains the singular verb "has" which does not agree with the plural subject "wildfires."
D - The phrase "due to drought . . ." is unidiomatic since "because of" (not "due to") should be used to modify the verb phrase "have become an ongoing threat."
E - Correct - The singular verb "has" agrees with the singular subject "the number of acres." Additionally, "because of drought . . ." is properly used to modify the verb phrase "have become an ongoing threat."

A - "instead of " - incorrect - not a substitute
B - "as opposed to" - incorrect - there is no argument
C - "in contrast with" - incorrect
E - "being" - incorrect - as use of 'being'- not entertained in Gmat .
