In 1-2 sentences, explain how to use an apostrophe to show possession for singular and plural nouns and to form contractions. please help

thank you

for me, balancing all your work/homework is the hardest part in high school and the exams.

the guest is my guess

i believe the answer is: b. mr. head had a long, tube-like face with a rounded open jaw and a short depressed nose.

this is because in the un-revised sentence it said that mr. heads face was long and tube-like, and he had a rounded open jaw. this is not a very grammatically correct because of how it seems to drag on with the and, replaced with, with, makes it sound more fluent in the description.
