Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - A 2021 study at a university examined the effect of walking on creativity. - 300 adults took part. - Half took a 20-minute walk before a creativity test; the other half sat quietly for 20 minutes. - On average, the walkers produced 60% more ideas on the test. - The results were published in a peer-reviewed journal.

The student wants to present the main result of the study. Which choice most effectively uses relevant information from the notes to accomplish this goal?

  1. A. In a 2021 study, adults who took a 20-minute walk before a creativity test produced, on average, 60% more ideas than those who sat quietly.Correct
  2. B. The 2021 study involved 300 adults and was published in a peer-reviewed journal.
  3. C. Half of the 300 participants took a 20-minute walk before the test.
  4. D. A peer-reviewed journal has reported that walking is good for creativity.

Answer: A. In a 2021 study, adults who took a 20-minute walk before a creativity test produced, on average, 60% more ideas than those who sat quietly.

The result is the difference the study found. Choice A states it with the comparison and the number that make it meaningful.

Why the other answers are wrong

B. The 2021 study involved 300 adults and was published in a peer-reviewed journal.
Sample size and publication are details about the study, not its finding.
C. Half of the 300 participants took a 20-minute walk before the test.
This describes the method, not what the study found.
D. A peer-reviewed journal has reported that walking is good for creativity.
This is vague — it drops the 60% figure and the comparison that make up the actual result.
