Question

why do onions make you cry?
onions add a lot of flavor to the meals we cook, but for some of us, cutting them is a real tear - jerker. our eyes start to burn and tears stream down our faces. when we slice into onions, they fight back!
but where do onions get their bite?
inside an onion, there are itty bitty bags of juice. when the onion is cut, the bags rupture and their juices mix, forming an acid. some of this acid turns into a gas that floats up into the air. that gas drifts into our eyes, where we immediately feel the burn—mega owie ouch! our eyes try to wash that wicked stuff away by turning on the water works, and tears start flowing. by the way, the juice also clings to your hands, so don’t rub your eyes or you’ll just make things worse. (yes, i learned that the hard way.)
but onion juice isn’t all bad. did you know that it’s strong enough to kill germs?
question 2
why can onions make us cry?
a. because onion juices mix to form an acid that turns into gas and burns our eyes
b. because onions carry germs called e. coli that cause poisoning and burns our eyes
c. because onion juices mix to make bubbles that float up and burn our eyes
d. because onions carry germs called salmonella that burns our eyes

Explanation:

The text on the left explains that when an onion is cut, the juice - filled bags rupture, the juices mix to form an acid, some of which turns into gas. This gas drifts into the eyes, causing a burn and tears. Option A matches this description. Option B is incorrect as E. coli is not related to the onion - crying mechanism described. Option C about bubbles is not in line with the text. Option D about salmonella is also not relevant to the described process.

Answer:

A. Because onion juices mix to form an acid that turns into gas and burns our eyes
