Is this sentence correct? If not, can you please help me come up with another that expresses the same thing?

Thank you for using the Jiskha Homework Help Forum, BUT where is the sentence?

Sra

Oh, sorry, forgot to copy paste... thanks for making me aware:) The sentence is

"This often serves as an argument for why reading is important to people."

Looks OK.

You could simplify it by saying:

This often serves as an argument for the importance of reading.

To determine whether a sentence is correct or incorrect, you can consider the grammar, syntax, and meaning of the sentence. Could you please provide the sentence you'd like me to check?
