Finally, someone developed the machines with paper rolls that could play the music of several instruments. We call them player pianos.
What is wrong with the first sentence?
A. It needs a subject.
B. It is a run-on sentence.

Answer 1

Answer: B

Explanation: I’m pretty confident in my answer but inform me if I’m wrong. Good luck!

Answer 2

Answer: B. It is a run-on sentence.

Explanation:

There should be a period or a coma after we, since the sentence changes to “all scene music boxes” which is a different subject and therefore it is a run on for the first sentence.
