Answer 1

He sold caps, didn't he?

• The question tags turn a sentence into a question. A sentence with a question tag inquires or asks something.
• Question tags are often used to validate the given information, whether it is true or not.
• The most common question tags used are - Don' they , aren't they , will they ? won't they ? and so on.
• For example - The dish is delicious, isnt' it ?
• Thus, the correct sentence is - He sold caps, didn't he?

Answer 2

Answer:

• 'He sold caps' is an example of Simple Past Tense, verb's past form 'sold' confirms it. So its question tag is : 'Didn't he?'. It is asking a question, therefore it is a question tag.

• The rewrite sentence is : He sold caps, didn't he?

• Positive Sentence takes negative tail and here they are 'he sold caps' ( positive sentence ) and 'didn't he?' ( negative tail ). 'Not' after 'did' confesses that didn't is negative. 'Tail' and 'tag' both are same and it is used in Conversations.
