(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.

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.

(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

(B) is incorrect.

in greater detail, the effects of calefaction, or warming, of a river than ever before

The comparison is lost when we split .... in greater detail than ever before ...

(C) brings it together and is correct.

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
- "makes" = incorrect b/c you're talking about plural subject (techniques), so the verb tense should be "make" instead

(B) make it possible to study, in greater detail, the effects of calefaction, or warming, of a river than ever before
- the correct idiom is: "in greater detail 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
- correct as is

(D) make possible the study of the effects of calefaction, or warming, of a river in greater detail than it ever was before
- "make possible the study" = awkward construction. also "than it ever was before" = just wordy, incorrect. this A/C is a trainwreck

(E) has made it more possible than ever before to study in greater detail the effects of calefaction, or warming, of a river
- "has" need be "have" because you're talking about plural subject (techniques). also "more possible...than ever before"? just weird. another trainwreck

Kudos please if helpful :)

Yes i like the post. I will like to add one more thing -

We use simple present tense for - facts, habitual action.
e.g Sun rises in the East ( a fact)
Ron jogs 3 miles every morning (a habit)

I don't see any of these cases w.r.t "New techniques in thermal-scanning photography".
The statement is telling me that such new techniques which don't exist sometime in the past now exist and are useful to study the effects of blah blah in greater detail. The use of simple present tense make will NOT be correct.

blah blah = the effects of calefaction, or warming, of a river

Hence I go with present perfect - "have made it possible to study". C it is.

This is a subtle case of a misplaced modifier. We need "than ever before" to be directly linked to "study in greater detail"

Here it sounds more like we're saying "The effects of calefaction or warming of a river than ever before" which creates a disconnect from the intended comparison.

The excessive use of commas to create modifiers within modifiers is also awkward, though this is a secondary problem.

Placement of phrases is an important factor, and bears a higher priority than style or wordiness.



it is great that you see the difference between simple tense and present perfect here. this difference is hard and basic.
simple tense is used to show a timeless fact or a condition which , we think,

it is great that you see the difference between simple present and present perfect here.

i think present perfect show an action existing for a time, from a past point to present while simple present, we think, exist indefinitely.
so, one is exist for a time and one exist indefinitely
gmat test this difference between two tenses often. this point is hard and basic.
whenever we see simple present, think that it exist indefinitely. this habit is the way to activate grammar, or to see grammar in action
