Hey You!
So, only courses and languages (such as French and Algebra 201) would be capitalised for highschool subjects. Math, algebra, geology, etc., will NOT be capitalised unless a course.
I believe the answer should be B.
D. How does the lack of sleep hurt someone's health?
C. Dealing with loss and personal growth
This option is most accurate because firstly, the excerpt mentions that the author experienced loss. This is apparent from the line in the excerpt "After suffering emotional and material losses...".
Answer: Nothing anymore, but you need to take a minute to think and say "when did I have a moment I look back on and still smile about" you know? Think about family, friends, music, animals, etc. :)
