What things had you () until you joined the military?

• A. Never learned
• B. Never learn
• C. Never learning
• D. Not learned

Answer: (A)

This question tests the past perfect tense with a negative adverb to describe something that hadn’t happened before a past moment. The natural form is had you never learned, which uses the past participle learned after the auxiliary had in an inverted question like this. The meaning is clear: before you joined the military, you had not learned these things at all.

The other options don’t fit because they don’t use the correct tense or form. Never learn shows the base form, not the past participle needed for the past perfect. Never learning uses the -ing form, which doesn’t pair with had to form the past perfect. Not learned would require a different word order (had you not learned) to be natural, whereas the given phrasing with never learned matches standard usage.
