Answer 2

‘They sang a beautiful song, didn't they’ is an interrogative sentence.

Explanation:

• In this statement the given sentence is to be converted to an interrogative sentence. Interrogative sentence is one in which a question is asked to a person.  

• Hence the affirmative sentence is converted to an interrogative sentence by using 'didn't they'. This is because the sentence is in past tense.  

• Otherwise words like 'dont they' can be used to denote the present tense. The ‘rest of the sentence’ remains the same.
