Question

1,An (immense,great) amount of money has been put into building the dam to control the river.
2.Doctors (contribute,attribute) the fall in the number of death from heart disease to improvements in diet.
3.The ad says the (minimum,optimum) requirements for the job are a Bachelor degree and two years’ experience.You don’t stand a chance without working experience

Answer 1

immense前面都用AN了,猜也知道是immense了.
attribute 归功于,contribute是做贡献,原意是医生把心脏病减少归功于饮食习惯的改善.
minimum 最小的,最低的.原意是广告说这工作的最低要求（minimum requirements）是学士学位和2年经验.optimum好象是最优的意思
