Answer is B) "Add the conjunction and after the comma."
In my opinion, the correct answer is <span>B. Sheila visited Paris last summer and climbed the Eiffel tower. A parallel structure in a sentence requires use of two or more instances of the same grammatical form; so, if it is, for example, simple present tense, it should be consistently used in all the clauses. In this case, we have perfect tense in both clauses, which makes these two actions parallel.</span>
The answer would be:
**D. Some people find Angelou's poetry to be inspiring and uplifting, but other people find it depressing. **
Why?
A is incorrect because the comma is *before* "but." That is grammatically incorrect.
B is incorrect because one can't have a semicolon if they're aren't two *complete* sentences.
C is incorrect because "But other people find it depressing" is not a complete sentence capital letter or not.
