So I spent my Friday evening blanching corn , cutting it off the cob , and spooning it into freezer bags . I used this funky device which I recently got from my grandfather 's apartment when he had to downsize to move into a nursing home . ( He 'll be 99 on Monday . Happy birthday , Grandpa ! )
According to the above context, answer the following question.
Why are they freezing corn ?


None of the above choices .
