no, it should be lime-green

You are correct. The sentence should be written as "The lime-green walls have not been painted" with a hyphen between "lime" and "green" to form a compound adjective.

The sentence "O The lime, green walls have not been painted." is incorrectly punctuated.

The incorrectly punctuated sentence is: O The door is hanging by its rusty iron hinge, and it may fall at any moment.

To identify the incorrectly punctuated sentence, you can review each option and look for any punctuation errors. In this case, the comma used before "and" is incorrect. The comma creates a comma splice, as it separates two independent clauses without a coordinating conjunction or appropriate punctuation. To correct the punctuation, you could either replace the comma with a period to create two separate sentences or add a coordinating conjunction after the comma, such as "but" or "so."

OI had a busy, industrious day at work today. (Missing comma after "industrious")

This sentence is correctly punctuated.
