A isnot correct.I think mod1 + subject + modifier2 , verb is fine. Bcz of parallelism error

D and B are correct interms of parallelism

A) Carefully conceived by NASA to stimulate microgravity, a device called an acoustic levitator, which can suspend tiny balls of liquid, using two speakers that project sound waves in opposite directions, and counteracting the force of gravity - usage of which is redundant

B) Carefully conceived by NASA to stimulate microgravity, having the ability to suspend tiny balls of liquid using two speakers projecting sound waves in opposite directions, and counteracting the force of gravity, a device called an acoustic levitator - Usage of "...,and counteracting..."---Having that ability leads to a counteracting effect, the usage of comma there offsets the clause and i felt, there are too many fragments of dependent clauses

C) A device carefully conceived by NASA for stimulating microgravity, called an acoustic levitator, which suspends tiny balls of liquid to use two speakers projecting sound waves in opposite directions and to counteract the force of gravity, - "...suspends tiny balls of liquid to use speakers..." - changes the meaning


D) A device carefully conceived by NASA to stimulate microgravity, called an acoustic levitator, can suspend tiny balls of liquid, using two speakers projecting sound waves in opposite directions and counteracting the force of gravity, i couldnt find any error in this

E) A device that was carefully conceived by NASA for stimulating microgravity and that can suspend tiny balls of liquid, using two speakers projecting sound waves in opposite directions - not very sure, but i feel using the two bits of info -
"that was carefully conceived" and "that can suspend" - being used with "and" in between doesnt seem right. Further, the clause "using two .." alters the meaning -- Device was conceived using two speakers -- device was conceived for a purpose(to suspend )

Was down to A or D. Crossed off A because the counteracting was just awkward - I think it was trying to do parallelism but failed.

B, C, E changed meanings

I personally had the same reasoning in my mind while solving this question.
So I ll also go for D.

I will go for D. It is parallel and the meaning is not altered.

A) Carefully conceived by NASA to stimulate microgravity, a device called an acoustic levitator, which can suspend tiny balls of liquid, using two speakers that project sound waves in opposite directions, and counteracting the force of gravity,(correct)

B) Carefully conceived by NASA to stimulate microgravity, having the ability to suspend tiny balls of liquid using two speakers projecting sound waves in opposite directions, and counteracting the force of gravity, a device called an acoustic levitator(parallelism and modifier error)

C) A device carefully conceived by NASA for stimulating microgravity, called an acoustic levitator, which suspends tiny balls of liquid to use two speakers projecting sound waves in opposite directions and to counteract the force of gravity,(meaning and modifier error)

D) A device carefully conceived by NASA to stimulate microgravity, called an acoustic levitator, can suspend tiny balls of liquid, using two speakers projecting sound waves in opposite directions and counteracting the force of gravity, (a device.. can spend..is now commercially available) Wrong

E) A device that was carefully conceived by NASA for stimulating microgravity and that can suspend tiny balls of liquid, using two speakers projecting sound waves in opposite directions (for stimulating)Wrong

Carefully conceived by NASA to stimulate microgravity, a device called an acoustic levitator, which can suspend tiny balls of liquid, using two speakers that project sound waves in opposite directions and counteracting the force of gravity, is now commercially available for use in industries and researches involving anti-gravity effects.

A) Carefully conceived by NASA to stimulate microgravity, a device called an acoustic levitator, which can suspend tiny balls of liquid, using two speakers that project sound waves in opposite directions, and counteracting the force of gravity,--- Looks the best bet as I see it. 'counteracting' is parallel to 'using'


B) Carefully conceived by NASA to stimulate microgravity, having the ability to suspend tiny balls of liquid using two speakers projecting sound waves in opposite directions, and counteracting the force of gravity, a device called an acoustic levitator --- having the ability' is poor diction compared to 'can'

C) A device carefully conceived by NASA for stimulating microgravity called an acoustic levitator, which suspends tiny balls of liquid to use two speakers projecting sound waves in opposite directions and to counteract the force of gravity,---- 'which suspends' is materially different from 'can suspend'.

D) A device carefully conceived by NASA to stimulate microgravity, called an acoustic levitator, can suspend tiny balls of liquid, using two speakers projecting sound waves in opposite directions and counteracting the force of gravity, -- read with the non underlined part, this a comma splice (run-on).

E) A device that was carefully conceived by NASA for stimulating microgravity and that can suspend tiny balls of liquid, using two speakers projecting sound waves in opposite directions--- incomplete, doesn't mention the levitator nor the counteracting.


In A, 'which' is not redundant. If you don't use 'which, the sentence will suffer from double verbing when read together with the nonunderlined part.

In Option A, which is the independent clause?

How can we have a sentence without an independent clause ?

Please read the entire sentence with the non-underlined part and the predicate will pop up. The choices per se are supposed to be substantive phrases that act as the singular subjects followed by the verb 'is'.
