Question

(12) Because the cave had no exposure to air, water, or living things its paintings and drawings remained intact.

1. What change, if any, should be made in sentence 12?
Remove the comma after the word air.
Change the word its to it's.
Insert a hyphen between living things.
Add a comma after the word things.

Answer 1

You would want a semi colon or a coma after living things. If you read it out loud theres a natural pause so I would place it there. It would flow easier and because its combining two ideas in one simple sentence I would choose C, add the coma
