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.

Original sentence has three mistakes.
1) Tense (simple)
2) Singular verb (makes)
3) misplaced modifier

Statement C corrects all this:

1) & 2) Tense and correct verb form. -Present perfect works best here as some thing that doesn't exist in past now exists. Also correct form "have made" is used.
3) modifier is at right place (to study in greater detail than ever before)

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.
