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?
large cages
wooden perches
some fresh water
keep out of cold

Answer D: keep out of cold.

 The phrase "keep out of cold" should be revised because it does not follow the same pattern used before in the sentence, which describes the needs of pet canaries: large cages, wooden perches, some fresh water. To add another item in this sentence, and sequence, it is necessary to use the same grammatical pattern. Revised, it can be: "...and being kept out of cold."
