1. For some birds the sense of smell appears to play a role in navigation, since pigeons with surgically removed olfactory nerves( were found to have increased difficulties) in homing.
b. have been found to have increased difficulty
e. have been found to have increasing difficulties
选B，E为什么不行？

2．The school board ruling mandating that physically handicapped students（ be placed in regular classroom settings whenever possible also assured all children who have a reading problem） of special aid.
d. be placed in regular classroom settings whenever possible also assured children with reading problems.
答案是D ，A不行吗？also assured all children who have a reading problem是什么成分，修饰谁？
多谢

E中的increasing和difficulties都不对。以前问过，你查一下。

whenever possible also assured all children who have a reading problem在此作状语，如果改为复数reading problems我认为也是对的，只是还是没有D简洁。

应该是The school borrd ruling (mandating that...whenever possible) also assured children...
whenever possible是前一个成分中的，而assure是整句的谓语。

peggymm，你是对的
