Sally wishes that she __ something different in college. had studied has studied was studied

## Step 1The sentence "Sally wishes that she __ something different in college" is a conditional sentence expressing a hypothetical situation in the past. In English, such sentences often use the past perfect tense in the if-clause (if part) and the conditional perfect tense in the main clause (wish part).## Step 2The correct form to fill in the blank is "had studied". This is because the past perfect tense is used in the if-clause, and the conditional perfect tense is used in the main clause.## Step 3The other options "has studied" and "was studied" are incorrect. "Has studied" is the present perfect tense, which is used to describe actions that happened at an unspecified time before now. "Was studied" is the passive past tense, which is used when the subject of the sentence is the recipient of the action, not the doer.
