E) scramjets, or supersonic combustion ramjets, can attain high speeds by reducing

after comma we need the subject to make the things clear. So A b and C are out

Comparing D and E

D the scramjets have the ability is ackward amd verbose

E is straight

I was confused about whether "by" in E is sufficient, or if we need another "by" before "letting". I guess what it boils down to is that both reducing and letting are being modified by "by", thus another "by" is superfluous.

This reasoning was not why I eliminated B/D.. B is wrong because the structure makes no sense.. "that high speeds can be attained.. is a result of their reducing.. and letting", it just sounds awkward and wordy. It also distorts the intended meaning of the author.

D is gone because "have the ability of" does not look good.. "can attain" sounds much better. Also, as it stands right now, the meaning of the sentence is ambiguous. It implies that these jets only have the ability to attain high speeds when they reduce X and let Y... That's not the correct intent of the author. They always have the ability to attain high speeds, and that's BECAUSE they reduce X and let Y. The relationship is not conditional.

E is correct because "can attain" removes any ambiguity and is concise, "by" implies that "jets can attain high speeds because of THIS specific process", and therefore we know that the relationship is not conditional; the author simply wants to state a fact.

Again, my only gripe with E was that I was unsure if "by" should also be put before "letting", and this made me waste a whole minute on the problem, which was stupid considering the other options were riddled with errors.

The very first word 'WHEREAS' indicates that a comparison is coming our way.
'Ramjet' follows 'whereas', therefore the there should be a jet name after the comma to show comparison. Whereas high speeds follow 'comma' which is wrong construction.

After reading the sentence we know that there is a comparison between the high speeds of ramjet and other jet.

Choices A, B, and C are out based on this logic.

The other construction is 'Ramjets can....' and 'scramjets or supersonic combustion ramjets can......'.
'by reducing....and letting....' are parallel. 'AND' introduces a list and that list must be parallel and must make sense in the context of the sentence.

Thus E .

"E" is the correct choice - Scramjets parallels a ramjet shows an effective contrast.
