Dear Friends,

Here is a detailed explanation to this question-

goodyear2013
From 1965 on, the region’s standard of living has soared, but also unemployment and prices.

(A) but also
(B) and also
(C) but so have
(D) and so also
(E) but so did

Choice A: In Option A, we see an error related to idiom use; the use of the phrase "but also" must be preceded by the use of the phrase "not only". Moreover, there is a parallelism error as the clause "the region’s standard of living has soared" does not parallel the noun phrase "unemployment and prices". Thus, Option A is incorrect.

Choice B: Option B shares the parallelism issue of Option A. Additionally, Option B changes the meaning of the sentence by using the word "and" in place of the word "but"’ the correct conjunction to use here is "but", as the intent is to show contrast. Thus, Option B is incorrect.

Choice C: Option C maintains proper idiom use, conjunction use, and parallelism throughout the sentence and conveys the intended meaning. Thus, Option C is correct.

Choice D: Option D alters the meaning of the sentence in the same way that Option B does, by using the incorrect conjunction "and". Thus, Option D is incorrect.

Choice E: Option E suffers from a verb form error that causes a breach in parallelism. As the first verb in this sentence is in the present perfect form, the second verb must be as well. Thus, Option E is incorrect.

Hence, C is the best answer choice.

I think the explanation for E) is not correct. two verbs can be in different tenses and still be parallel

Hello Schachfreizeit,

We hope this finds you well.

To clarify, what we meant to say in this explanation is that in this case, the tense of the first verb indicates the tense of the second.

We hope this helps.
All the best!
