Question

if necessary, add or remove commas from the sentence.
context: i have only one science tutor.
my science tutor sidney crosby wrote a catchy song about the solar system.

Explanation:

The context confirms there is only one science tutor, so the name "Sidney Crosby" is a restrictive essential clause that does not require commas—removing it would leave the sentence unclear about which tutor is referred to, but since there is only one, the name identifies the specific tutor without needing non-restrictive commas.

Answer:

My science tutor Sidney Crosby wrote a catchy song about the solar system.
