Like the power generating appartus

[sanjaylakhani]

Like the power-generating apparatus of a
conventional car, that of a hybrid car
depends on a combustible fuel to generate
power.

A. that of a hybrid car depends on
B. hybrid cars depend on
C. hybrid cars’ power-generating apparati are
dependent on
D. that of a hybrid car’s is dependent on
E. that of hybrid cars depend onincome as business revenue.

Can anyone pls explain as to why C is wrong? is it beacuse of plural- apparati- that violates parallelism

first, please take the extra 1.5 seconds to type out complete words such as "please" or "on". this will make things easier for both our readers and our moderators; thank you.
there is absolutely no reason to abbreviate a two-letter word.
ever.

correct; since the first half of the comparison (the power-generating apparatus of a conventional car) is singular, the parallelism is solid if the second half is singular as well. it doesn't make strict logical sense to compare one apparatus to more than one apparatus.
this may be the first time i've ever seen the word 'apparati' in print. crazy stuff.

--

note also that 'are dependent on' is needlessly wordy; it should just say 'depend on'. this is the sort of thing that may not seem like a big deal when you look at it, but these things are a very big deal indeed to the gmat writers.

Pls also comment n use of LIKE-

like is the proper comparison word here, because the comparison is between nouns (noun phrases, to be exact), not clauses.
were you looking for more than that?

[dubinskysoares]

well i agree with the explanation you have provided,although i seem to recollect a rule that states -use 'like' to compare nouns,noun phrases...

Could you please elaborate slightly on the use and the necessity of the word "that here"!

Hi,

"that" in this sentence is referring to the "power-generating apparatus" of a hybrid car. It is required because you are comparing the power generating apparatus of a conventional car to the power-generating apparatus of a hybrid car.

If you do not use "that", you will end up comparing the power generating apparatus or a conventional car to a hybrid car. This is logically incorrect.

Hope this helps
