Two problems with "but also":
1. The complementary part "not only" is missing. However even if "not only" were there, there could be parallelism issue: a. From 1965 on, NOT ONLY the region’s standard of living has soared, but also unemployment and prices.: Wrong - parallelism between clause (the region’s standard of living has soared) and noun phrase (unemployment and prices). Note that "have soared" in the second element of the parallel structure cannot be omitted because the word "have" does not occur in the first part of the sentence. b. From 1965 on, NOT ONLY the region’s standard of living has soared, but also have (soared) unemployment and prices.: Correct - compares clause with clause. The word "soared" can be eliminated from the second element because the word already occurs in the first element of the parallel structure.
2. Now ignore the above error and consider that "but also" can be used without "not only" (in fact it can be, but not ideally in GMAT). Now (in option A) arises a parallelism issue ( similar to the one mentioned in 1a above.) The parallelism is between clause (the region’s standard of living has soared) and noun phrase (unemployment and prices). The part "have soared" in the second element of the parallel structure cannot be omitted because the word "have" does not occur in the first part of the sentence.
Thus option A ("but also" alone) is wrong in 2 ways.

Good question! After "but" we need a verb to have both parts parallel. So A,B and D are out. Between C and E. Here we have "from 1965 on", which means that action started in the past and is still valid. Hence we need present perfect. E is out, C is correct choice.

I agree that an auxiliary verb is needed to keep both sides of the question parallel. Eliminate A, B and D. The first part of the sentence uses present perfect, so the second part should also. Eliminate E. It is also interesting to ask yourself when solving some questions whether there is a contrast or not in the sentence you are considering. Soaring standards of living are positive, but rising prices and unemployment are negative, so a contrast is needed. You need “but”.

A B and D elimnated.
Need a but - C & E left.
First part of sentence contains 'has'. The event started from point in the past and continues today, thus use 'have'

Dear sayantanc2k , what a wonderful explanation! One kudo seems not enough!
Well noted for your explanation. In addition, I want to ask, how if I change the statement into :
From 1965 on, NOT ONLY the region’s standard of living has soared, BUT ALSO unemployment.
I removed the prices, so we only have one noun in right side. Is it correct that in this case, we can OMIT "has"?
close
68% (00:24) correct
