Sentence correction

[RonPurewal]

you don't even need that ^^ to eliminate D, though. if you just COMPARE the choices, you'll notice that choice D is clearly inferior to the correct answer in at least 2 ways:

1/
• "not yet having been incorporated" (objectively worse / less efficient / unnecessarily wordy)
• "not yet incorporated" (objectively better)

2/
• "models that are used..." (objectively worse / less efficient / unnecessarily wordy)
• "models used..." (objectively better)

either of these is already a sufficient basis for eliminating D and keeping the more efficient version.

Team,

Please confirm.

Is 'they' really ambiguous in options B and E. If I think logically, it makes sense.

Also, please if you can help me in explaining the error(s) in option E.

Warm Regards

Hi Rajat, I think that in the Option E the "aspects" is missing a bonafide verb.

In answer E, the main verb is "is"; try cutting out the modifiers to see this for yourself. There are other problems with this sentence.
