I'd go with (D).

This is future conditional, so I would eliminate (A) and (B) since they do not have "would".

I would eliminate (E) because of the faulty comparison. Comparing "know a great deal" and "now" is not apples to apples.

Your remaining choices are identical except for economic v. economical. Economical sounds weird to me in this context, so I'd go with (D).

b. have to know a great deal more than they do now about the social and economical
c. would have to know a great deal more than they do now about the social and economical
d. would have to know a great deal more than they do now about the social and economic.
e. would have to know a great deal more then now about the social and economical.

help

A,E --> comparing "have to know a great deal" vs "now" ---> INCORRECT.

"have to know a great deal" vs "they do [know]now" --> Proper comparision

B,C,E -- economical -- which means "cheap" is not appropriate in this contest

Economic means "having to do with the economy or the study of economics."

Economical means "careful or prudent in managing finances, money- saving."

D is the best.

IMO, D

'would have' is used in conditional statement
Would as a verb tense should be used only when a condition involving If is present.

D is appropriate; but OA is said to be E.
may be OP made a typo by mistake and typed then as opposed to than. Still,
more than now as opposed to more than they do now is right?

should be (D).

I dont agree with OA.

'economical' is wrong in this context. Also the comparison is wrong in E

I go with D.

First of all, A is incorrect due to nonparallel structure
B, C, E are eliminated due to incorrect word use "economical"

I'll go for "D".

But, there is one question in answer choice "D" THEY refers to what? Population or Demographers? Is this ambigous or Ok?

First the word has to be "economic" and next is the comparison.

I will go with option D

IMO D as well.

Another reason for the OA NOT being E is because of the use of 'economical' instead of 'economic' which can imply that the 'detriments' were 'economical' whereas the correct use is 'economic detriments'.
