There are few things worse for a new parent than listening to a baby scream in hunger while a bottle of formula slowly warms up in a bowl of hot water. So why not just pop the bottle in the microwave and zap it in 20 seconds? Because microwaves heat fluids unevenly, and a hot pocket in the formula could seriously injure the baby. Which of the following is presupposed in the argument against heating formula in the microwave?
A.
Babies generally refuse to eat formula that has been heated in a microwave.
B.
Microwave radiation might break down some of the proteins in formula that are vital to a baby's health.
C.
Different microwaves use different amounts of power, and consequently some models could heat a bottle to scalding temperature faster than others.
D.
Parents cannot be expected to consistently even out the temperature of a microwaved bottle by shaking it vigorously before giving it to the baby.
E.
Once formula has been heated, any leftover formula should be discarded, because otherwise the formula could spoil between feedings and make the baby sick.
