Task: Question Answering
Input (English): Passage: Feeding a small baby is an important task . Small babies or infants need special food that is just for them . They drink only mother 's milk or baby formula .  Here is how I feed a baby . First I place the mother 's milk in a bottle , or I mix the dry formula and water being careful to measure the correct amounts of both in the baby bottle stirring until the powder is completely dissolved . Then I place the bottle in a pan of water on the stove and warm it until it feels just slightly warm .  Not too hot and not too cold .  When the milk is ready , I hold the baby with one arm and hold the baby 's bottle with the other hand and let the baby drink .  When the baby is finished drinking help her burp . I put a cloth on my shoulder and hold the baby against my shoulder , and gently pat her back until she burps . When she burps she usually spits up a little milk which is caught by the cloth .  Now the baby will usually want to sleep . Question: What should the baby not swallow? Option1: Milk. Option2: air
Output (English): air
