Answer:
c. the one about sam
Step-by-step explanation:
i would say c is definitely not an answer because his shortfall of sleep is caused by an addiction to video games, therefore he is not experiencing stress and there is no contxt evidence that could say he plays games because of stress. answer a isnt the answer either becuase this is just cause and effect only about her sleeping schedule. lemme reword that tho, she sleeps very late in mornings so this is what causes her to not be able to sleep the next night. no evidence to prove she is stressed. sam however has an important test, it is human nature to worry about it and this is why he is .not sleeping well.
