2.was it on october 1,1949______the people Republic of China was founded?
a.in which b.on that c.that d.when

Answer 1

第一个选d,其实是i think which is of grear help to our daily life ,which在这是状语提前，第二个选c,是强调句，原来的语序应该是it was on october1,1949that the people Republic of China was founded.that前面不需要介词了，判断一个句子是不是强调句很简单就是看that 后的句子成分是否齐全也就是它是不是一个句子，在这that后的句子意思是中华人民共和国成立了，显然成分齐全，所以是强调句。强调句的句型是it be(am,is was等)that。所以当然选c

Answer 2

目的状语
