Answer:
The phrase "keep out of cold" should be revised for a more parallel sentence.
Explanation:
The sentence "Pet canaries need large cages, wooden perches, some fresh water, and keep out of cold." is not parallel, because of the examples: large cages, wooden perches, some fresh water, and keep out of cold. The first three examples are parallel because they describe the things canaries need, and the last example is something they do not need. So, to make this sentence parallel, the last example needs to be "and kept warm" because "kept warm" will be something canaries need.
