Gmatprep上几道题目请教NN

1. The investigation of many psychologist and anthropologists support the generalization (of there being little that is a significant difference) in the underlying mental processes manifested by people from different cultures.

A. of there being little that is a significant difference
B. of there being little that is significantly different
C. of little that is significantly different
D. that there is little that is significantly different
E. that there is little of significant differences

其他几个选项都错在哪里，D似乎很罗嗦，不简洁

２. Five fledgling sea eagles left their nests in western Scotland this summer, (bringing) to 34 the number of wild birds successfully raised since transplants from Norway began in 1975.

这题应该用bringing, 但我不知道如改为and they brought是否也对?

谢谢

第一题同位语从句，E的little of改变了句子的意思；

第二题，逻辑意思不对，是Five fledgling sea eagles left their nests in western Scotland this summer这个事件造成了后面的变化，they（Five fledgling sea eagles）本身不能bring to 34

1）of there being的用法awkward
2）little修饰对象是不可数名词，a difference/differences可数，矛盾
3）同位语从句，感觉C/E of的用法意思有点不同的
