Proponents of artificial intelligence… Explanation
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
Computers that will be used to diagnose, deciding, or other purposes. This list isn’t parallel.
(B) as an expert does, which may be used for purposes such as diagnosing equipment breakdowns or deciding whether to authorize a loan
The “which” should be next to computers. Try removing it. …as an expert does may be used for purposes such as diagnosing equipment breakdowns
(C) like an expert—computers that will be used for such purposes as diagnosing equipment breakdowns or deciding whether to authorize a loan
(D) like an expert, the use of which would be for purposes like the diagnosis of equipment breakdowns or the decision whether or not a loan should be authorized
Similar “which” issue to B. It’s the computer not the expert. Use “such” for example (don’t use “like”). The list is also a mess.
(E) like an expert, to be used to diagnose equipment breakdowns, deciding whether to authorize a loan or not, or the like
to be used to diagnose, deciding, or the like. This list isn’t parallel.
