在第五段的第二句:
Indeed, if you take baby tree swallows out of a nest for an hour feeding half the set and starving the other half, when the birds are replaced in the nest, the starved youngsters beg more loudly than the fed birds, and the parent birds feed the active beggars more than those who beg less vigorously.
其中 if you take baby tree swallows out of a nest for an hour feeding half the set and starving the other half
feeding half the set and starving the other half是因為前面有take (baby tree swallows) out (of a nest)這個動詞了，所以才改成動名詞型式嗎?
另外half the set是指half of the baby tree swallows?
其中set是否是以下意思(https://reurl.cc/28841a)? 謝謝。
set (noun): a group of similar things that belong together in some way
