Proponents of artificial intelligence say they will be able to make computers that can understand English and other human languages, recognize objects, and reason as an expert does—computers that will be used to diagnose equipment breakdowns, deciding whether to authorize a loan, or other purposes such as these. (A) as an expert does—computers that will be used to diagnose equipment breakdowns, deciding whether to authorize a loan, or other purposes such as these
A的错误在于没有对computers的三种可能用途做并列表述。deciding应该改为“decide“。而”other purposes" 前应该加上“for”。 所以对A的改正应该是“computers that will be used to diagnose..., decide.., and for other purpose such as these."
