I went with B over C although I liked it for its present perfect tense because "the effects of calefaction, or warming, of a river" in C is just way too detached from "the study". Almost like by the time I got to "the effects.... ", kind of lost focus of "the study"..... :cry: B did better on that front by giving sufficient emphasis to the content of the study (inspite of the commas and all)

GMAT english seems to be very different from everyday English- but then not like I'm a native English speaker anyway :-D

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
phrase "in greater detail than ever before" modifies the verb and should be placed right next to it
(B) make it possible to study, in greater detail, the effects of calefaction, or warming, of a river than ever before
"in greater detail than ever before" should not be separated. Otherwise, we need another subject and a verb to make it work.
(C) have made it possible to study in greater detail than ever before the effects of calefaction, or warming, of a river. Correct
(D) make possible the study of the effects of calefaction, or warming, of a river in greater detail than it ever was before. They key here, I believe, "the study in greater detail" is inferior to "to study in greater detail. A study that is more detailed than ever before would have made D more attractive than it is now.\

(E) has made it possible than ever before to study in greater detail the effects of calefaction, or warming, of a river subject-verb agreement

In this SC problem, I am having a hard time understanding the rule regarding selecting "have made it" in answer choice (C) over "makes it" in answer choice (B). Doesn't the subject "techniques" require "makes"?

Thanks for any advice you all can provide me.

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.

By rule of grammar, - make it possible - is not ungrammatical although -have made it possible - conveys the meaning of the context better; Secondly the word order in B is erroneous with - than ever before - modifying the warming of a river. It should rightly modify - in greater detail - as in C.

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.
