His studies at the University of Chicago were concentrated on mathematics,astronomy,and philosophy,which earned him a bachelor of science degree in 1910.
答
（His studies at the University of Chicago主语）（ were concentrated on mathematics, astronomy, and philosophy系表结构）, （which earned him a bachelor of science degree in 1910定语从句,修饰主语）这里没主语从句,而是词组作主语.
