Answer 1

Answer:

What would you have done if Ms. Adams __returns___ the package unopened?

Answer 2

What would you have done if Ms. Adams had returned the package unopened?

This is the correct statement.

The given sentence is in simple past perfect.

Past Perfect tense:

• The pluperfect (short form of plusquamperfect) and is commonly referred to as past perfect in English, is a verb tense that refers to an activity that took place earlier than the given point in the past.
• English examples are "we had arrived" and "they had written."
• Since the pluperfect combines the past tense with the perfect aspect, it is now more commonly referred to as the past perfect in English grammar (for example, "had written").
• The same phrase is occasionally applied to the grammatical structures of other languages.
• The past perfect progressive (or past perfect continuous) form in English is "had been writing."

Hence, the correct answer to be used in the blank is had returned.
