knewton sc vr 2

The test results came back more quickly than the radiologist had expected them to, revealing the presence of benign tumors; fortunately, benign tumors, which are harmless, are non-progressive growths that do not metastasize and which can be excised before becoming malignant.

A benign tumors, which are harmless, are non-progressive growths that do not metastasize and which
B benign tumors are harmless non-progressive growths that do not metastasize and that
C benign tumors are harmless non-progressive growths that do not metastasize and which
D these harmless non-progressive growths do not metastasize, and benign tumors that
E these non-progressive growths, harmless growths that do not metastasize, are benign tumors that

Hi!
IMO B

The main issues here are parallelism, wordiness and use of 'which'/'that'

1. Parallelism
(A) 'which are harmless' - this is additional information, let us skip it, and check for parallelism.
"...that... and which..." this structure is not parallel
(C) "...that... and which..." this structure is not parallel

2. wordiness
(E) "non-progressive growths, harmless growths" this construction is wordy
It should be simply "non-progressive harmless growths"
This answer is also illogical.

3. 'which'/'that'
'That' and 'which' are in GMAT not interchangeable.
The clause introduced by 'which' should immediately follow the noun or idea it modifies. [1]
It refers to answers A and C.
(D) Neither 'that' nor 'which' should be used here, simply without pronoun

Hope it helps!
Thanks,
Maciej

A - looks like it has parallelism which .........which ....keep as a contender.
B - looks good is parallel. Keep as a contender.
C - That .......which. Non parallel, do not keep choice.
D - Awkward construction - benign tumors that do not ..........
E - Redundant use of growths, and this choice is wordy

Coming to A and B.

Look carefully, A is faulty parallelism. The first 'which' comes in a non essential clause and the second in an essential clause, thus the parallelism does not accord equal importance to the parallel sections of the sentence, hence discard A.

B - can not be eliminated

Hence pick B

according to mgmat sc strat guide, parallel relative clauses need to have the same relative pronoun

B) benign tumors are harmless non-progressive growths that do not metastasize and that -> isn't the second "that" refers to the phenomenon "harmless non-progressive growths that do not metastasize" and not to the "harmless non-progressive growths"? This makes it sound awkward.

What's the OA?
