Question tests comparisons. First split up can be done using the first clause. The right idiom is X more than Y or X than Y. So A and B can be eliminated.
E can be eliminated because its not as clear as C & D. Opposite could be anything : hot water warms slower than cold water or cold water freezes slower than Hot water.
Between C and D. C is incorrect because would denotes possibility whereas its already discovered.

A) more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water

B) faster; the researchers who investigated this effect also discovered that cold water heats faster

C) more quickly than cold water; the researchers who investigated this effect also discovered that cold water would heat more quickly than warm water

D) faster than cold water; the researchers who investigated this effect also discovered that cold water heats faster than warm water

E) faster than cold water; the researchers who investigated this effect also discovered that the opposite is true

The “Mpemba effect” refers to the fact that hot water freezes more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water and named that phenomenon the “inverse Mpemba effect.”

Quote:
A) more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water

Here more must be followed by than not more in comparison to.
More than is idiomatic.
More in comparison is unidiomatic.Erase A


Quote:
B) faster; the researchers who investigated this effect also discovered that cold water heats faster
Here nothing wrong.
Faster looks fine and the rest of the sentence has no issues.
Keep it for now.

Quote:
C) more quickly than cold water; the researchers who investigated this effect also discovered that cold water would heat more quickly than warm water
Would...???
why would there is nothing hypothetical so usage of would is wrong.
Erase C

Quote:
D) faster than cold water; the researchers who investigated this effect also discovered that cold water heats faster than warm water
no idiom error.
Comparison fine
Compare D and B
D has better meaning
Quote:
E) faster than cold water; the researchers who investigated this effect also discovered that the opposite is true
I don’t know what the opposite really means(hot..hot...cold hot!) D was better written and clearly written
Erase E.
So D is the winner.
I hope this is the answer.Waiting for the OE to clarify my everlasting doubt.
I know that meaning wise B sounds wrong(faster..than what light????)

The “Mpemba effect” refers to the fact that hot water freezes more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water and named that phenomenon the “inverse Mpemba effect.”

A) more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water
B) faster; the researchers who investigated this effect also discovered that cold water heats faster
C) more quickly than cold water; the researchers who investigated this effect also discovered that cold water would heat more quickly than warm water
D) faster than cold water; the researchers who investigated this effect also discovered that cold water heats faster than warm water
E) faster than cold water; the researchers who investigated this effect also discovered that the opposite is true

MEANING
Researchers who investigated the M effect ("hot water FREEZES faster than cold water") also discovered that "cold water HEATS faster than hot water" and named that the inverse M effect.

X freezes faster than Y, means that the freezing rate of X is greater than that of Y.
X freezes more quickly than Y, means the same thing, but this is less concise than the former option.

A) "more quickly in comparison to" unidiomatic; "more quickly in relation to" unidiomatic and unintended;
B) "hot water freezes faster"…than what? missing what is hot water being compared to; also "cold water heats faster"… than?
C) "more quickly than" less concise; "cold water WOULD" imps the effect doesn't happen anymore, nonsense;
E) "opposite is true" what is the opposite? this could imply many things, (ie. cold freezes slower than hot?) unclear;

Answer (D)

Decision Points: "faster than" is more concise than "more quickly in comparison to" or "more quickly than"

A) more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water

B) faster; the researchers who investigated this effect also discovered that cold water heats faster - Faster than what? We need a second entity for comparison.

C) more quickly than cold water; the researchers who investigated this effect also discovered that cold water would heat more quickly than warm water -"heats" is the correct verb tense because we're describing a fact.

D) faster than cold water; the researchers who investigated this effect also discovered that cold water heats faster than warm water -Correct

E) faster than cold water; the researchers who investigated this effect also discovered that the opposite is true - Opposite is true is ambiguous.

A) more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water
B) faster; the researchers who investigated this effect also discovered that cold water heats faster
C) more quickly than cold water; the researchers who investigated this effect also discovered that cold water would heat more quickly than warm water
D) faster than cold water; the researchers who investigated this effect also discovered that cold water heats faster than warm water
E) faster than cold water; the researchers who investigated this effect also discovered that the opposite is true

So I am not absolutely sure but I guess "more quickly" is redundant.
Also the fact that when you have usage of faster it is definitely more concise than more quickly.
For this reason I would get rid of A and C.

Even though B has no grammar based errors, The removal of compared to "hot/cold water" is not right. We cannot just say faster. So that takes care of B.

Quote:
D) faster than cold water; the researchers who investigated this effect also discovered that cold water heats faster than warm water
E) faster than cold water; the researchers who investigated this effect also discovered that the opposite is true

The only difference between D and E is at the end. E says "the opposite is true". Though it is true it is very unlikely that the author will leave it to the reader to assume what is the opposite. Unless it is a very simple (cannot come up with an example).

For this reason D is the best choice.

Option A: The “Mpemba effect” refers to the fact that hot water freezes more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water and named that phenomenon the “inverse Mpemba effect.” The use of more quickly in comparison to and more quickly in relation to is unidiomatic. more quickly than is required. Eliminate option A.

Option B: The “Mpemba effect” refers to the fact that hot water freezes faster; the researchers who investigated this effect also discovered that cold water heats faster and named that phenomenon the “inverse Mpemba effect.” hot water freezes faster than what? Incomplete comparison. X freezes faster than Y. X is cold water, Y is not given. In addition, the idiom is incomplete in the first clause. Likewise, in the second clause, cold water (X) heats faster than[/i] [i]Y, than is missing thereby making the use of faster in the clause unidiomatic. Y is missing from the comparison, so another incomplete comparison. Eliminate B.

Option C: The “Mpemba effect” refers to the fact that hot water freezes more quickly than cold water; the researchers who investigated this effect also discovered that cold water would heat more quickly than warm water and named that phenomenon the “inverse Mpemba effect.” The presence of would heat more quickly in the second clause suggests uncertainty in the second discovery. A discovery is a fact, and hence must be stated in the simple present tense rather than the conditional tense. In any case conditional tenses express cause and effect, so where is the cause? Eliminate option C.

Option D: The “Mpemba effect” refers to the fact that hot water freezes faster than cold water; the researchers who investigated this effect also discovered that cold water heats faster than warm water named that phenomenon the “inverse Mpemba effect.” The comparison is complete and logical in this option. The idiomatic use of faster than in this option is correct. The sentence has a clear meaning. Keep.

Option E: The “Mpemba effect” refers to the fact that hot water freezes faster than cold water; the researchers who investigated this effect also discovered that the opposite is true and named that phenomenon the “inverse Mpemba effect.” Opposite of what is true? This leaves a lot of room for speculation. This option is inferior when compared with option D because it is not clear in meaning compared with option D. Eliminate E.

The answer is option D.

A) more quickly in comparison to cold water; the researchers who investigated this effect also discovered that cold water heats more quickly in relation to warm water

B) faster; the researchers who investigated this effect also discovered that cold water heats faster --unclear; hot water freezes faster than what?; cold water heats faster than what? warm water or hot water?

C) more quickly than cold water; the researchers who investigated this effect also discovered that cold water would heat more quickly than warm water

D) faster than cold water; the researchers who investigated this effect also discovered that cold water heats faster than warm water -- correct; and provide clear information

E) faster than cold water; the researchers who investigated this effect also discovered that the opposite is true-- not the opposite

Therefore, D

Generis I have a doubt . When comparing actions

Should we use does or did at the end of sentence.

Eg: should we have to
Hari runs faster than John
Hari runs faster than John does.

Same as the above example.
In the sentence above we should be saying :
Hot water freezes faster than cold water does.

Or is it just hot water freezes faster than cold water.
