Question

taye is on a cruise with his family when he begins experiencing nausea, stomach cramps, and diarrhea. he sees the ships doctor, who tells taye that he has been exposed to norovirus. taye is also confined to his quarters until the ships doctor confirms that he no longer has norovirus. which statement best explains this precaution? there is no telling which food taye ate to give him the norovirus. norovirus doesnt only spread on food but also from person to person. tayes symptoms would be distressing for other passengers to see. the doctor suspects that taye had the norovirus before boarding.

Explanation:

Norovirus is highly contagious. It can spread through contaminated food (but not only through food) and also through person - to - person contact (e.g., by touching surfaces contaminated with the virus and then touching the mouth, nose, or eyes). Confining Taye to his quarters is a measure to prevent the spread of the virus to other passengers.
The first option about not knowing which food caused the virus does not explain the confinement (as confinement is about preventing spread, not about identifying the source). The third option about symptoms being distressing is not the main reason (the main reason is preventing spread). The fourth option about the doctor suspecting Taye had the virus before boarding is not relevant to the current confinement (which is about the current state of having the virus and preventing spread).

Answer:

Norovirus doesn't only spread on food but also from person to person.
