Why should 'instead' be followed by a noun phrase? After all, 'instead' is not a preposition; 'instead of' only is a prepositional phrase and must be followed by a noun or a noun phrase. Instead simply means 'in that place'

'Rather' is used when we wish to show some discrimination or preference favoring one over another. When such preference is absent, it is ok to use 'instead', IMO. In the given case no preference for use of high-pressure fluids is shown over steam. It is just that hydraulic machines use a particular process compared to the other type of machines.

But/rather/ but rather all demands parrallel structures. Instead is a complex preposition so it can forego parallel rules

I was looking at the semicolon used to connect two completely correct sentences. Are they complete sentences on their own? chetan2u help. Each seems complete
And that would rule out A B

Yes this is right. Both parts have subject and verb. Hence we can use semicolon

I think just because they are complete sentences doesn't mean you HAVE to use a semicolon. But if you do use a semicolon, there can't be a connector, so E is definitely out.

I'm curious about the claim that "but rather" and "but instead" can be correct according to MGMAT. It'd be nice to get a final ruling.

a) water, but rather
b) water, but instead
c) water; instead
d) water; rather
e) water; but

According to some gmat rules, "rather than" can take on either a clause or noun,
while "instead of" goes with only a noun.
In the question above, the portion after the underlined part is clearly a clause; in that case,
the correct response should be
[Reveal] Spoiler:
D
right?


a posting in this forum teaches me a similar problem. now to post the knowlege again.

rather work as a preposition. we need two words of the same kind which go with rather. I rather you. I eat rather than play

instead work as a preposition and as a adverb. as an adverb, instead dose not need two words of the same form

but is used to show a contrast which dose not make sense inhere. instead is better. a,b and e are out. this is meaning error.
in d, rather has no two words of the same form. it is wrong grammatically.

this is hard because the meaning error is hard and the grammatical error is subtle .

e) water; but


OFFICIAL EXPLANATION


Correct Answer: C

This sentence is connecting two independent clauses and so needs a conjunctive connector or semicolon to link the two. Answer (E) can be eliminated for redundantly using both a semicolon and the conjunction "but". Additionally, the meaning of the contrasting conjunction "but" is incorrect here; the contrast this sentence draws between hydraulic machines and steam-powered machines is more appropriately illustrated with the adverb "instead". Answers (A) and (B) can be eliminated for using "but." Answer (D) can be eliminated for using the ambiguous adverb "rather", which may be modifying the adjective "high-pressure" or the verb "are transmitted". Additionally, "rather" expresses a preference for one choice over another; the idiomatic "instead" is a better fit, leaving (C) as the correct answer.

C -for me. Most succinct in meaning and clause construction

Machines powered by hydraulics are not driven by the steam produced by boiling water, but rather, high-pressure fluids are transmitted throughout the machine to various motors and hydraulic cylinders.

a) water, but rather - there should be a 'by' 'but rather by' - cause we are connecting two processes
b) water, but instead - but instead; are two words with two tonal indications- but indicating contrast and instead, indicating an alternative - very slight difference, but it exists
c) water; instead - seems valid. Following semi colon, we have the complete independent clause (appropriately after semicolon and 'instead'). Sentence would read as "water; INSTEAD, high-pressure fluids are transmitted throughout the machine to various motors and hydraulic cylinders.)
d) water; rather - incorrect tone
e) water; but - incorrect word, there is no contrast, as such

Hope it is C! :)

I eliminated A & B because of the idiom "Not X, but Y" where in this example we have "not DRIVEN, but RATHER" where the part after "but" would need to immediately have a verb like driven afterwards to be correct.

was my reason for eliminating A/B correct? Thanks :D
