Hello,
Could you please explain to me what a comma splice (run-on) is? I do not understand how D is wrong here. I thought a was wrong because there was a comma before "and counteracting".

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,

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

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,

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,

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

Hi, in A, is the "using....& counteracting" phrase modifying the relative clause started by WHICH?

Is that grammatically allowed? Modifier, INDEPENDENT CLAUSE, relative clause, participle modifying relative clause, REST OF INDEPENDENT CLAUSE.

Hi,

Perhaps if you can make it clear why that construction is A is not grammatically allowed, it will be helpful.

If the modification of participles of the previous relative clause is wrong (or at least that is what I understood from your observation), can you pl. elucidate what would be the correct version? '

I am just trying to enlighten what grammar the topic has slipped from.

Thanks for your prompt and angle.
