Answers:

649). OA - C - right tense

Explanation: George’s personal diary and album formed the basis of his book (that he wrote) about the places (that) he had visited.

Here perfect tense is unnecessary in the sentence "he wrote about the places that he (had) visited"

We can do without it since there is no confusion regarding the timeline.

Further, in the reduced form, construction in E, with perfect tense, is highlighting an inappropriate sequence of actions: he visited those places before his personal diary and album formed the basis of his book.

654). (OG 10th Ques no - 81) - OA - B

OE: To establish the clearest comparison between circumstances in 1973 and those in 1984, a separate clause is needed to describe each year. Choices A and C, in failing to use separate clauses, are too elliptical and therefore unclear. Choice A also incorrectly uses and and a semicolon to separate an independent clause and a phrase. Choice D incorrectly separates two independent clauses with a comma; moreover, the placement of in 1984 is awkward and confusing. In choice E, that refers illogically to income, thereby producing the misstatement that income rather than mortgage payments rose to forty-four percent in 1984. Choice B is best; two properly constructed clauses that clearly express the comparison are separated by a semicolon.

A - incorrect - use of semicolon is wrong
Read: Using semicolon

C - incorrect - use of comma wrong

D - incorrect - use of comma wrong
Read: Editing Comma Splice

E - incorrect - pronoun error - that incorrectly refers to income
