Practice one SAT question at a time
Questions come from the Bluebook question bank.
While researching a topic, a student has taken the following notes:
- Crown shyness is a phenomenon in which the tops (crowns) of neighboring trees grow close together but don’t overlap.
- To explain how this happens, Australian forester M.R. Jacobs proposes the mutual abrasion theory.
- According to Jacobs’s theory, when trees brush against one another, branches break off.
- Malaysian scholar Francis S.P. Ng posits the mutual shade avoidance theory.
- According to Ng’s theory, when tree branches detect shade from nearby trees’ branches, they stop growing.
The student wants to compare the causes of crown shyness proposed in the two theories. Which choice most effectively uses relevant information from the notes to accomplish this goal?
