Based on information in Text 1, which sentence states the author's primary claim?
A. The main reason schools should adjust start times is to save money on transportation.
B. Students in elementary school also benefit from changing school start times because they have more
energy in the morning.
C. An increasing body of research supports the idea that starting school later in the day has significant
benefits for teenagers.
D. Teenagers miss fewer classes when they begin school later in the day.
Explanation: a primary claim is sort of like the “main idea”, or the idea that an author is going to prove. A, B and C are longer sentences, and would be ones that were used to prove or further explain the main idea.
