Recognized as one of history's most influential scientists, Paul Dirac helped to revolutionize the field of physics; his contributions to the theory of quantum electrodynamics were more valuable than were almost any other physicists of his time.

Meaning: PD (one of the most influential scientists) helped to improve field of physics; his contributions were more valuable than contributions of the rest of scientists were.
Looking at underlined part, we can simply see that this question is all about the comparison in the second half of the sentence. The value of contributions of PD is compared with value of contributions of the rest of scientists. So we need to find a correct way of stating this comparison.

A) than were almost any other; this choice implies that we are comparing value of contributions of PD with value of others!, which is absolutely wrong as compared entity are not logically parallel.A is out

B) than were those of almost any other; Here "those of" comes in handy; now we are comparing value of contributions of PD and value of contributions of others. Correct.

C) than almost any; this choice implies that we are comparing value of contributions of PD with any scientists of PD's era including himself!!!. that really sucks C is out

D) than almost any other; this choice implies that we are comparing value of contributions of PD with others themselves!. D is out

E) as were those of almost any; in comparatives we need "than" as proposition not "as". E is out.

Recognized as one of history's most influential scientists, Paul Dirac helped to revolutionize the field of physics; his contributions to the theory of quantum electrodynamics were more valuable than were almost any other physicists of his time.

Pure comparison question, let's see sentence structure:
Attachment:

When we use comparative forms for comparison the structure is "more...than, less...than, higher...than", so eliminate (E).
POE

A) than were almost any other
(is out as explained above)

B) than were those of almost any other
("those of" -plural pronoun - refers to plural "contributions", and this constraction logically compare Paul’s contributions with contributions of other physicists)

C) than almost any
(comparison between Paul's contributions and any physicists - illogical)

D) than almost any other
(comparison between Paul's contributions and other physicists - illogical)
----
C) than almost any
D) than almost any other

structure of these answers is exactly the same, so why we need to prefer one to another, it is nonsensical,
in such situations better to ignore them both

----
E) as were those of almost any
(more...as - unidiomatic, but comparison here is fine)

To me SC Comparison questions are nightmare.
But Sir Charles' Comparisons, Part I and Comparisons, Part 2 are the nugget, it's really helpful to clarify some tricky comparison moments.

(B) is the winner

I will go for (B)

Two reasons:-

1) Than is important hence E is out
2) Comparison should be logical hence A, C & D are out

"B" for me. Since his contributions should be compared with not a person, but with others' contributions. Thus, B and E are the only choices left. "E" does not use a comparative form "than" (with more valuable). Thus, leaving us with "B".

A) than were almost any other( incorrect comparison, contributions are being compared with other physicists)

B) than were those of almost any other( correct comparison, contribution are being compared with contributions of other physicists)

C) than almost any( incorrect comparison)

D) than almost any other( incorrect comparison)

E) as were those of almost any( more than is correct, more as incorrect)


Will go with choice B

Thanks

A) than were almost any other
B) than were those of almost any other
C) than almost any
D) than almost any other
E) as were those of almost any


His Contributions should be compared with the contributions of other scientists. With this in mind, Only B does this

A, C and D have Incorrect comparison, Comparing contributions with scientists

B) than were those of almost any other - Correct Answer

E) as were those of almost any - valuable than will be used, we are showing a contrast.

Comparison question ... Paul's contributions being compared with the contributions of other physicists.

A) than were almost any other
--> In this option, Paul's contributions are being compared to the physicists themselves!
Complete sentence - his contributions ..... were more valuable than were almost any other physicist of his time
Clearly, it is senseless comparison and hence option A is out.


B) than were those of almost any other
--> Looks good. Correct comparison. Paul's contributions and other physicists'contributions.
Complete sentence - his contributions ...were more valuable than those (the contributions) of almost any other physicist..
Keep option B. Likely answer.


C) than almost any
--> Same reasoning as in option A. Wrong comparison. Paul's contributions vs physicists! Illogical.
Option C is out.


D) than almost any other
--> This option is no better than option A/C. Again the wrong things are being compared here (P's contributions vs physicists).
Option D is out.


E) as were those of almost any
--> part of the sentence before the underline has the comparative word more . This requires "than", so that "more than" can be used to compare two things (two similar things of course! :tongue_opt2 ).
Although this option rightly uses "those" of to compare P's contributions with "those" (the contributions) of other physicists, it can be eliminated because of the above mentioned reason.
Option E is out

Therefore option B is our answer!

Hope this helps :)

Recognized as one of history's most influential scientists, Paul Dirac helped to revolutionize the field of physics; his contributions to the theory of quantum electrodynamics were more valuable than were almost any other physicists of his time.

A) than were almost any other
B) than were those of almost any other
C) than almost any
D) than almost any other
E) as were those of almost any

OFFICIAL EXPLANATION

aditya590550 SheilyKamra and CAMANISHPARMAR (poster of awesome PS questions)- welcome!

• The sentence with option A improperly compares the value of Dirac's contributions to physicists of his time.

• In order to correct the parallelism error, use those of almost any, so that the sentence properly compares the value of Dirac's contributions to the value of contributions made by other physicists.

• Eliminate A, C, and D

• Idiomatically, more valuable must be completed by than, rather than as, so eliminate E

The correct answer is B

COMMENTS

The parallelism issue is probably the hardest

Recognized as one of history's most influential scientists, Paul Dirac helped to revolutionize the field of physics; his contributions to the theory of quantum electrodynamics were more valuable than were those of almost any other physicists of his time.

In order to maintain parallelism, we need
• a pronoun/person and pronoun/person
HIS and OF OTHER PHYSICISTS
• a verb and a verb
WERE and WERE
• the object of the verb (noun) and a parallel term (pronoun)
CONTRIBUTIONS and THOSE

There are some really good answers here. People who follow you will be thankful.

Best answers go to aditya590550 , RamSep , and GKomoku (I am glad that Sir Charles helps!) -- regular kudos

RamSep and GKomoku I am bumping you both again. I will try doing so in reverse order; this bumping system may be alphabetical.
I almost never bump on SC Butler. I just wanted to recognize you both for your excellent work and effort on both questions.

Honorable mentions go to KanishkM sonusaini1 and SheilyKamra -- smiley faces

Nicely done!

Although I am late to jump to this, I will give it a go.

Quote:
Concept Tested:- A's Contribution more valuable than B's Contribution.


Quote:

Quote:
A) than were almost any other

A's contribution compared with physicists. wrong.

Quote:
B) than were those of almost any other

A's contribution compared with contribution of other physicists. Great !! Keep it.

Quote:
C) than almost any

A's contribution compared with any physicists. wrong.

Quote:
D) than almost any other

A's contribution compared with physicists. wrong.

Quote:
E) as were those of almost any

'More than' is correct idiom. Not 'More as'

Therefore B is correct.
