Read the sentence. pet canaries need large cages, wooden perches, some fresh water, and keep out of cold. which phrase should be revised for a more parallel sentence?

Keep out of cold

because, blocking out the rest would make it say "pet canaries need keep out of cold" which is not a proper sentence

it should say "to be kept out of cold", or something along the lines of that, so when the rest is blocked out, it says "pet canaries need to be kept out of cold"
