A different variety of giant tortoise can be found on every island in the Galapagos, each with its own style of oversized dome and comically scrawny neck.

(A) each with its own style of oversized dome and comically scrawny neck

(B) each with their own styles of oversized domes and comically scrawny necks

(C) each having their own style of oversized dome and comically scrawny neck

(D) all having their own styles of oversized domes and comically scrawny necks

(E) all with their own style of oversized dome and comically scrawny neck

the answer is A, my question is, "a variety of " usually should be followed by plural nouns? Eat a variety of foods, a variety of acti vities... here it is followed by single noun tortoise..

could any NN help to explain how "variety" is used?thanks.

the answer is A,but I am also confused by this "variety".......

dd,有没有人来切磋一下这个variety

机井出现过专门考这个考点的

consult the dictionary: tortoise [pl.] tortoises 或 tortoise

可是新东方的网络课堂说GMAT不考单复数辨认的亚，难道还要背一下这些单词，ft..

為什麼不是(E)?

独立主格为什么可以放在句末?

我记得语法书上说复数名词, each +...呀..
