Combine these two sentences into one sentence with a single subject and a compound verb. jarvis likes jazz. he often attends jazz concerts.

The combined sentence would be Jarvis likes jazz and often attends to jazz concerts.

Explanation:

The subject in both parts is Jarvis, therefore, is not strictly necessary to use a subject more than once. if we combine the information the pronoun He becomes unnecessary. The verbs are likes and attends the second verb can use a proposition to become a compound verb and connect everything in a single sentence.
