求助：a group of xxx动词单复数问题

4Hs

A South American bird that forages for winged termites and other small insects while swinging upside down form the foliage of tall trees, the graveteiro belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and that are represented in virtually every kind of habitat.

A graveteiro belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and that are
B graveteiro belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and is
C graveteiro belongs to the ovenbird family, a group of New World tropical birds that include more than 230 species and is
D graveteiro, which belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and that are
E graveteiro, which belongs to the ovenbird family, a group of New World tropical birds that includes more than 230 species and is



我选了c，我认为that就近修饰birds所以用复数，后面的is我觉得是修饰graveteiro的。

但是答案是b，解释说这里includes和include都行，但是要和后面平行，所以用的单数。

我的问题是：

1. 想知道到底 a group of xxx后面单数还是复数？

2. 如果is是修饰graveteiro的，是不是and前面要加逗号，使其与插入语分开？

在线等答案！谢谢各位大大！

探讨下你的第二个问题。我觉得and不需要加逗号，因为加了逗号is就和belongs平行了，变成南美州那个鸟被represented，这是明显不对的。这里is后面的内容应该修饰a group，而且and后面是省略了that，所以可以确定不用加逗号。

谢谢你的回答哦~
是的啦~
所以我问如果is是修饰那个gxxxxx的，是不是应该在and前加逗号，正因为这里没有加逗号，所以判断为和includes平行，所以选b不选c嘛~~~

B选项中的is 和includes平行吗？ 如果加上that变成that is 还对吗
