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).

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.

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?

Economic > economical.

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?

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'.

OA is D.

Q41 - OG12:
Verb form; Logical predication
Th is sentence explains a hypothetical situation and therefore calls for a conditional—or contraryto- fact—construction, because in order to more accurately predict population, demographers would have to know more than they presently
know. A present-tense verb is required to describe the current state of demographers’ knowledge, and the comparison made by the sentence must be
between current and conditional knowledge, not between knowledge and time of knowing (now). A Wrong comparison—between knowledge and time (now); conditional verb is needed. B Conditional verb is needed; economical is the
wrong adjective. C Economical is the wrong adjective. D Correct. Conditional knowledge, indicated by would have to know, is correctly compared
to current knowledge. E Wrong comparison—between what demographers need to know and now.

The correct answer is D.

I will choose D

social and economic --> economic means related to finance ---> intended meaning

economical -thrifty ---> changes the meaning of the sentence --> making the fertility sound economical

A is clear OUT

D is left.

E is an incorrect answer on the Sets key...
The correct answer is D.

You need an economic at the end and not "economical"

It has to be D.

Economic is the right word which is present only in A and D options. A is incorrect because of invalid comparison. That leaves D as the right choice.

Hey Noburu,

Just to weigh in real quickly, we don't want "efficient" here. We want "economic", meaning "related to the economy" (economy meaning "wealth and resources" of a region or country). We want to know how economic (money-related) factors relate to fertility, etc.

Hey All,

I got asked about this privately, but I think the same question was asked by mymisc as well. The question is, do we need the "would" here, and why? The issue is that this sentence is a hypothetical/conditional:

To develop more accurate population forecasts

We could reword this as "If we wanted more accurate forecasts, demographers..."

In a conditional construction, we need the "would". Look at how it would work in a NON-conditional:

To develop accurate population forecasts, demographers have to know a great deal more...

See how, in that example, without the "more," we're just talking about a fact (how forecasts are developed accurately)? But with the conditional, we need the complete conditional construction, with "would."

Let me know if you have any follow-up questions!

To develop more accurate population forecasts, demographers have to know a great deal more than now about the social and economic determinants of fertility.

A. have to know a great deal more than now about the social and economic
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 than now about the social and economical

E had written wrong it is not "economical". In the original exam,gmatprep 2, it is written "economic".

so i picked up E why it is not true.

I chose E can anyone explain it pls?

To develop more accurate population forecasts, demographers have to know a great deal more than now about the social and economic determinants of fertility.

A. have to know a great deal more than now about the social and economic
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 than now about the social and economic

it is the right question.

"Than they do now" is necessary because it clarifies that comparison is between demographer's current knowledge of social and economic determinants and future knowledge. Hence. I will pick D

D, too.
OA is incorrect.
I read this online.... ( I would post the link here, but as a new member I am not allowed to post links yet.)

--------------------------------

Economic vs. economical


There are many cases of word pairs such as cyclic and cyclical for which the difference in meaning is minimal. However, there are also similar pairs for which the difference is great. Economic and economical are one such pair.


Economic has to do with the economy, or an economy, be it global, national, or personal: the constant flow of money. Meanwhile, economical refers specifically to something that functions so well that it saves money, so that it is cheap to use. Economical, therefore, has a much more specific meaning than economic.




For examples;

1 - Incorrect - At the summit, the leaders discussed a number of economical issues.

- Correct - At the summit, the leaders discussed a number of economic issues.


2 - Incorrect - We have decided to trade in our car for a more economic one.

- Correct - We have decided to trade in our car for a more economical one.

My choice is D.

A and B refer present tense, whereas the statement refers something in future.

E had 'econimical' which can be eliminated as per the context of the statement.
