The phrase should be kept. Eliminate (C) and (D). The phrase does more to introduce the time
period as a topic of discussion than to describe Tolstoy himself, so eliminate (A). The correct
answer is (B).
- D Notice the wording changing in the answer choices. The great scientists were also the great
philosophers is the only choice that is consistent with the second half of the sentence, which
says the great mathematicians were also the great theologians. Choice (D) is the correct
answer.
11. C Again, notice the wording changing in the answer choices. In the sentence, it is not clear what
the underlined portion, the pronoun another, is referring back to. Choice (C) clarifies this
confusion and is consistent with the idea in the previous sentence that scientists were also
philosophers and mathematicians were also theologians. The correct answer is (C).
