An essay argues that the school day should start later. Read the main ideas of its three body paragraphs:
Para 1: Teenagers' natural sleep cycles make it hard for them to wake up early.
Para 2: Starting school later would mean after-school sports would end later in the evening.
Para 3: A later start time is linked to better academic performance and attendance.
Which paragraph's main idea is least effective in supporting the essay's overall argument?
A.Paragraph 1, because it focuses on biology instead of school.
B.Paragraph 3, because academic performance is not the most important factor.
C.Paragraph 2, because it presents a potential problem or counterargument, not a benefit.
D.All paragraphs are equally effective and well-organized.
Challenging
A student plans to argue that dogs are better pets than cats. They've structured their main ideas as follows:
I. Dogs are very loyal.
II. Dogs can be trained to do many tricks.
III. Dogs are friendly and playful.
What is the most significant weakness in this organization, and how could it be improved?
A.The ideas are too different; they should all be about loyalty.
B.The argument is one-sided; it should include a main idea about why cats are good pets.
C.The ideas are too similar; they should be grouped into one paragraph about a dog's positive personality.
D.The structure is weak because it only lists positive traits of dogs instead of directly comparing them to cats on specific points.
