Expression of Ideas practice question
While researching a topic, a student has taken the following notes:
- A study found that adults who take a daily walk report better sleep.
- The study relied on participants' own reports of sleep.
- Participants chose whether to walk.
- The researchers suggest a trial with sleep measured by monitors and walking assigned at random.
The student wants to present the finding while conveying that it is not yet proof. Which choice most effectively uses relevant information from the notes to accomplish this goal?
- A. Daily walkers reported better sleep, but with sleep self-reported and walking self-chosen, the researchers themselves call for a trial that measures sleep with monitors and assigns walking at random.Correct
- B. A daily walk improves sleep.
- C. The study relied on self-reported sleep.
- D. The researchers suggest a further trial.
