255. Dr. Tonegawa won the Nobel Prize for discovering how the body can constantly change its genes to fashion a seeming unlimited number of antibodies, each specifically targeted at an invading microbe or foreign substance.
(A) seeming unlimited number of antibodies, each specifically targeted at
(B) seeming unlimited number of antibodies, each targeted specifically to
(C) seeming unlimited number of antibodies, all specifically targeted at
(D) seemingly unlimited number of antibodies, all of them targeted specifically to
(E) seemingly unlimited number of antibodies, each targeted specifically at
Why A is wrong?

Dr. Tonegawa won the Nobel Prize for discovering how the body can constantly change its genes to fashion a seeming unlimited number of antibodies, each specifically targeted at an invading microbe or foreign substance.

(B) seeming unlimited number of antibodies, each targeted specifically to
(C) seeming unlimited number of antibodies, all specifically targeted at
(D) seemingly unlimited number of antibodies, all of them targeted specifically to
(E) seemingly unlimited number of antibodies, each targeted specifically at

I always get wrong when there is a construction like [adverb/adjective] [adverb/adjective] [noun]

Please some one help me to identify correctly in these type of constructions.
As per the meaning of sentence how the body can constantly change its genes to a antibodies . So it should be a adjective to modify the antibodies .Asusual i ended up wrongly with these constructions

E is correct. adjectives only modify nouns while adverbs can modify verbs, phrases, and other adverbs.

in this case, seemingly (an adverb) is modifying "unlimited number of antibodies"

"seeming" is an adjective and therefore wrong so we can eliminate A, B, and C. between D and E, "targeted.. at" is preferred over "targeted.. to"

egmat, VeritasKarishma : can you please provide a proper explaination why we have to choose seemeingly . as per my understanding unlimited number of antibodies , is it acting as prepositional noun ?

KarishmaB - Can you pls review my 2nd reason listed below and confirm if it's the right one.

Option D is wrong for 2 reasons -

1. Idiom error - Targeted at is needed
2. All of them changes the meaning. All of the antibodies target at an invading microbe vs each of the antibodies specifically target at an invading microbe.
For eg - let us say an microbe enters the body so one specific antibody will target at the microbe instead of all the antibodies, and that's why option D is wrong as we want to convey that only specific antibody will function based on invading microbe.
