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.
答案是(E) seemingly unlimited number of antibodies, each targeted specifically at
逗號後面的 each targeted specifically at 是用來補充說明前面的 antibodies嗎?

恩恩...是阿
其實主要子句為
" Dr. Tonegawa won the Nobel Prize for discovering how the body can constantly change its genes to fashion a seemingly unlimited number of antibodies "
後面的
" each targeted specifically at an invading microbe or foreign substance. "為修飾antidodies的部份
正確應該為
; each antibody is targeted specifically at an invading microbe or foreign substance by people.
分號 省略; antibody已知省略; is 變being 也省略; 後面的by people 是已知事實(抗體是被人用)也省略
