Than is there in B.
Why do we require perfect tense here?
IMO B


You are right, but IMO if you look carefully you will observe that THAN in B is attached to THE EFFECTS: "the effects [...] than ever.." which makes no sense.

IMO the sentence would be equally correct with MAKE or MADE, but HAVE MADE is coherent providing that the research has been completed recently.

So the key is the subject and the placement of THAN.

C is clear and concise. B unnecessarily complicates by adding a few commas

I initially picked C but then the construction "...in greater detail than ever before the effects..." didn't sound very pleasing to me. And so I picked D...

Can anybody tell me what is wrong with D?

Sorry. I was watching this discussion. There is a nice discussion about the usage of "it" on this thread -

sc-australia-76438.html?highlight=SaraiGMAXonline

As explained by GMAT Instructor.

1. It can have a referrent
2. Or it can be used as expletive (place holder), which doesnt refer to anything

My 2 cents -
What we should worry about is whether "it" is ambiguous. Unless that happens don't worry too much. :)

One way to understand why B is wrong is that B has so many commas, you can likely to eliminate immediately in Gmat since Gmat looks for short, precise and clear sentence

B) Techniques is a plural term. Obviously it requires a plural verb make.

C) Now the substance of the sentence is that new techniques made it possible in the past, make it possible presently and will make it possible in the future to study in greater detail. The right tense to denote such a day-to-day affair is the use of simple present. Hence make it possible rather than have made it possible.

between B & C,
present perfect makes a better sense, however, apart from tense I can not realize how we can rule out B due to placement of comparative forms of which I'm suspicious.

noboru...I think that "it" in D has no clear reference . Ideally "it" should point to study but here the conflict is between "river" and "study" .

option D
Techniques make possible the study of the effects of calefaction, or warming, of a river in greater detail than it ever was before

IMO there are two issues.
ISSUE 1:
in greater detail seems to modify river rather than the study

ISSUE 2:
The Two items compared are not grammatically parallel. On the left side of the comparison, we have - the study of a river: NOUN + Prep MODIFIER. On the right side, we have - it ever was before : SUBJECT + VERB.

Hi all,

I do not understand why we use "make it possible" here while "it" doesn't refer to any antecedent????

Thank you.

IMO c is not better . it doesn;t sound very well.. c--have made it possible to study in greater detail than ever before the effects of calefaction, or warming, of a river

I think the effects og calefaction of a river should follow the study. it is the object of the study.

so I think it will be better when we say that : have made it possible to study the effects of calefaction,or warming, of a river in greater detail than ever before.

how about this one ?

It is C
First of all the verb must be in agreement with the plural subject. So 'make' and 'has' are out. Only C brings in the comparison properly

C is correct. Let us see why.

New techniques in thermal-scanning photography, a process that records radiation from surface areas, makes it possible to study the effects of calefaction, or warming, of a river in greater detail than ever before.

(A) makes it possible to study the effects of calefaction, or warming, of a river in greater detail than ever before
(B) make it possible to study, in greater detail, the effects of calefaction, or warming, of a river than ever before
(C) have made it possible to study in greater detail than ever before the effects of calefaction, or warming, of a river
(D) make possible the study of the effects of calefaction, or warming, of a river in greater detail than it ever was before
(E) has made it more possible than ever before to study in greater detail the effects of calefaction, or warming, of a river

New techniques is plural. Therefore makes is wrong. A,E out.
D is wrong because it is unidiomatic.
B/w B and C: The phrase
Quote:
in greater detail than ever before.
is one long modifer that should modify study, not the effects of cal... or warming.
