First of all, I saw a small typo in this
slide, it should be 'malignancy is not'. In
the test that you took, it would be 'malignancy is not' only, just an is missing
here. Now, let's solve this question. The
main difference I see is in the usage of
'because' and 'in that'. Since, it is talking
about an intrinsic property and not a
direct cause-effect relationship, 'in that'
is always better.
Therefore, options A and B can be
eliminated. Option D is passive in 'not
being self limited in its growth', this
can be eliminated. C and E are close
choices. Let's compare them vertically.
Had this 'is' not been there, this would
become a very easy choice, we added it;
is here, 'is not self-limited' okay, 'not having
is every time' or 'having it once' is alright. 'capable of invading into
adjacent tissues' and the main difference
is in this part, 'and may be capable of'
and this says, 'and spreading to distant
tissues it may be capable of'. This is the
main difference, this makes the sentence
a bit wordy and, more importantly, awkward,
and therefore, between C and E, very close
choices, C is a better choice.
