Benjy is 5 years old. he can put a dish into the microwave and press the "2" button to cook for 2 minutes. one day, he sees his mother wipe the front of the microwave with a damp paper towel before she presses a number button. after that, benjy rubs the front of the microwave with a napkin before he presses the number button. why? group of answer choices

To clean the exterior and keypad of the microwave.

Explanation:

It is proper to clean the exterior of the microwave including the keyboard. Although this isn't required to be done daily, Benjy saw his mum do it at the time she decided to clean it (maybe it was stained too) and being a child he picks up the act too.

It is advisable to clean not only the interior of your microwave but the exterior top including the keypad. Cleaning the keypad prevents dirt and dust from staying in them and causing the keypads to get stuck.

I hope this helps
