114). Astronomers have theorized that the Big Bang governs the behavior of interstellar dust, particles that comprise the atoms and molecules created in the progenitive explosion and persisting in even the emptiest regions of space.
D. they persist
E. are persisting
113). A is the correct answer. This question tests the use of present vs past participle.
Subject in the given sentence is filigree
The filigree spawned by X not mentioned in the sentence some 10,000 years ago. Thus the use of past participle. Further, spawned by denotes passive voice which justifies the use of past participle.
As for the extending, it is still prevailing today in the Michigan forest so you cannot use past participle extended.
The present and past participles are used to describe the filigree, they act as adjectives
114). OA - A - This question again tests the use of present vs past participle
In the given sentence, we can clearly see that for the 1st participial phrase, the action of created happened in the past and is passive. The second participial phrase starting with persisting implies that the atoms and molecules are still persisting in the present, they are performing the action of "persisting" hence the use of present participle.
B - incorrect - violates parallelism (2nd participial phrase becomes a clause)
C - incorrect - use of persisted is wrong - illogically suggests that atoms no longer persisted
D - incorrect - violating parallelism
E - incorrect - violating parallelism (2nd participial phrase becomes a clause)

Choice B properly uses a verb phrase (resulting ...) instead of which to modify the action of the first clause and also correctly completes either with or, but the verbs following either and or are not parallel: spreading must be spread to
Choice C is flawed by the nonparallel verb spreading and the wordy phrase that begins with the result of.
Choice E is similarly wordy and uses and where or is required.
