New techniques is a plural subject and demands a plural verb. So, A and E are out.
The problem with D is the ambiguous "IT" at the end because it seems to be referring to something but the meaning is not complete.
Among B and C: Why does in greater detail need to be within commas? Redundancy. Also it seems like in greater detail is not necessary to complete the meaning of the sentence. In other words like a which or a that its a limiting phrase.
Finally if you look at B without the limiting phrase: make it possible to study the effects of calefaction, or warming, of a river than ever before. Does this even make sense? The phrase "than ever before" has to be preceded by the action it modifies which is "in greater detail". So, B is clearly WRONG.

Choose C and move on.

(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

C is the answer - clear meaning and comparison usage of 'greater...than'

A & E - wrong - because of subject verb
B - wrong because greater ... than are not connected
D-wrong - bad structure - 'make possible ????'

Quite a straightforward one I'd say. Firstly, techniques being the subject requires that the verb be plural. Given this situation, you can eliminate options A and E. Among those that remain:

(D) make possible the study of the effects of calefaction, or warming, of a river in greater detail than it ever was before
Unnecessarily wordy and awkward.

(B) make it possible to study, in greater detail, the effects of calefaction, or warming, of a river than ever before
Awkward construction with the numerous commas.

(C) have made it possible to study in greater detail than ever before the effects of calefaction, or warming, of a river
Best option. It conveys the point crisply.

make vs have made is the issue here...Rest are easy to eliminate

Every time I am rejected by Harvard, my friends make it possible for me to endure the rejection
My friends have made it possible for me to endure the rejections at Harvard

Here too the meaning implied is the same as that implied by B...

A is something that the friends do every time to help me
B it is the friends that help me

Clearly the main problem is to decide between the shortlisted options of B and C.
In B, while it is grammatically correct, it does not fully convey the meaning. The sentence shows that these are the techniques X and techniques X make Y possible...
However, in C it correctly provides context of saying that it is techniques X which have made it possible to do Y. It makes giving credit to technologies X for being able to do Y much more clear and also implies that it is impossible to do Y in the absence of X

Well ,I am still not convinced by the OA, and confused between B and C.
Yes, I agree that have does appear nice.
BUT as per my knowledge in GMAT it is preferred to use Simple tense as much as possible unless the sentence is not grammatically wrong AND perfect tenses are generally not used.

I am afraid you are wrong to a very great extent. If you go with such notions into the exam, you will end up only getting the short end of the stick.
There are three simple tenses in grammar. i.e. a simple past, a simple present, and a simple future. It is not clear which one you are referring to.
The right perspective is that one should use the correct tense as the context demands. I do not think there is any preference, said either explicitly or implicitly by GMAT in the choice of the tense.
It must also be noted that most of the higher level questions involve the use of past and present perfect tenses or the use of the third conditionals in GMAT

Thanks a lot sir,
Sir , the tell me whether my reasoning is wrong??
The reason for which C is the correct answer is because the option stresses on the effect of new technologies
And this the effect is still IN THE PRESENT

Hi

Don’t you feel that there is no difference between B and C as far as new techniques are concerned? C is better because of the superior word order; in B, the placement of ‘than ever before’ after the river is changing the meaning.

Okay..Sir
You mean to say since there is a different sense in B i.e ‘than ever before’ stresses on river rather than the effects.
So for a better and less ambiguous explanation we have chosen C

Am I right???

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.

let's use the e-gmat 3 step process...

1. understand the meaning
new techniques allow to study smth in more details than it was possible before
what to study? the effects of C or W of a river.

2. error analysis
first error that jumps in the eyes is the SV agreement error. The noun is plural "techniques", while the verb is singular "makes".
A and E make the same mistake.
Since the techniques were not always present, I think it is more appropriate to use the present perfect - an action that happened in the past, but whose effects are still felt in present.

a. makes it possible to study the effects of calefaction, or warming, of a river in greater detail than ever before
as discussed above

b. make it possible to study, in greater detail, the effects of calefaction, or warming, of a river than ever before
while make does not make 100% incorrect this answer choice, the placement of "than ever before" definitely makes it incorrect.

c. have made it possible to study in greater detail than ever before the effects of calefaction, or warming, of a river
looks good!

d. make possible the study of the effects of calefaction, or warming, of a river in greater detail than it ever was before
it does not make possible the study. it made possible to study in more details. this option changes the meaning of the sentence.

e. has made it more possible than ever before to study in greater detail the effects of calefaction, or warming, of a river

C looks to be the winner.

New techniques are plural - hence either make or have

B gives an impression (by placing "in greater detail" in a non-restrictive clause) that study is now possible and it was not possible before.

First picked up B but then I went with C...other than the past participle form greater and than should be placed nearer to each other....

(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 possible than ever before to study in greater detail the effects of calefaction, or warming, of a river

IMO:
S-V error so A and E are out.
In D it has no clear referent so out
Between B and C simple present vs present perfect : simple present is used to describe facts and general practice whereas present perfect is used to describe something that started before the current time and its effect continue in the current time.So, C is correct.

A uses singular verb for plural subject New Techniques.
B the modifier is correct the underlined part should modify the preceding clause.
D again repeats the error in B
E uses singular verb for plural subject New Techniques.

(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

IN B : In greater detail ______________than ever before
IN C: study______________ the effects of calefaction, or warming, of a river

why C is better than B?

Although B is wrong because of tense error, also use of pronoun "IT" but C => have made it possible to study in greater detail than ever before the effects of calefaction, or warming, of a river => separate POSSIBLE TO STUDY______THE EFFECTS OF CALEFACTION
isn't it somewhat wrong

(A) makes it possible to study the effects of calefaction, or warming, of a river in greater detail than ever before -"makes" is singular
(B) make it possible to study, in greater detail, the effects of calefaction, or warming, of a river than ever before -in greater detail is very far from the clause "than ever before"; as a result, the comparison isn't making much sense
(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 -"it" doesn't has any antecedent
(E) has made it more possible than ever before to study in greater detail the effects of calefaction, or warming, of a river -"has" is singular
