I got A.

B C and E are all poorly worded and make it sound like the number of unsolved problems were exactly as many as the total number of problems that ‘confounded mathematicians’.



D is overly wordy

in choice A. we can not understand "confounded" as an adjective because we need "do" after 1950
if we add "do"
twice as many as confounded mathematics of 1950s do

then, the above sentence is correct ? is that righ?

in this case the sentence is
the mathematics discovered many unsolved problems , twice as many as the mathematics of 1950 do

i think this is correct?

is that right ?

choice A , I call, is "no subject in the second clause of comparison" case.
in gmatprep we have similar sentence
7 pesons have been killed by sharks, fewer than have been killed by bees. you can google to find out this problem

we can not understand that way because we compare unsolver problems with problems that confound. ok, I get this point

I chose B at first. I now understand why option B was wrong.
But I was looking at the other options. Here are my thoughts. Please help to correct my understanding.

1. C is wrong because we are not clear of 'what' is 2 times the problem in the sentence

2. the comparison should have been made between mathematicians and mathematicians . However , in D, they are making comparison between mathematician and problems . That is why it is wrong
3. Same problem as mentioned in point 2 for Option E. Hence, option E is wrong.

Have I analysed the answer choices correctly?

Dear Experts
Need help in eliminating with reasoning.
How can A be correct. Meaning wise, it doesn't seem great.
D seems better in meaning.

Why is B out.

rahul16singh28 Sure. First off, it works just fine to compare modifiers rather than nouns, so we don't need to add the words "the problems." When we do, it creates a potential misinterpretation. We could read this as "Mathematicians discovering twice as many unsolved problems as the problems that confounded mathematicians did." In other words, grammatically, we are comparing mathematicians to unsolved problems. This might seem like a really crazy way to read the sentence, but the structure creates that expectation. Think of the sentence "I scored ten goals, twice as many as the top player on the opposing team." Notice that here I'm comparing what I did to what the other player did. That's the same structure we see in D.


Hello DmitryFarber,

Thanks for the post.
I, however, am still struggling with understanding the issue with D.
How is A more clear than D?
I think the part 'twice as many as problems that confounded..' rightly presents the comparison of "the number of unsolved problems that the mathematicians are trying to solve" with the "number of problems that confounded mathematicians in....".
Where am I going wrong?
Would you please assist here?

I was also thinking like you and marked option D which is incorrect as option d is comparing number of problems whereas in A we are comparing mathematicians discovering problems with the number of mathematicians of 1950s and confounding is working as adjective that is modifying mathematicians of 1950s
hope i was able to help you

Only seven people this century have been killed by the great white shark, the man-eater of the movies—less than those killed by bee stings.

(A) movies—less than those

(B) movies—fewer than have been

(C) movies, which is less than those

(D) movies, a number lower than the people

(E) movies, fewer than the ones

look at above problem from gmatprep. choice b is OA. what we learn is that
in some comparisons, the subject/second element of comparison is cut off and implied. if we know this pattern, we can easily accept our OA.
