Expression of Ideas practice question

While researching a topic, a student has taken the following notes: - A study asked 500 adults to keep a diary of their screen time and mood for a month. - Days with more screen time were reported as lower-mood days. - Both screen time and mood were self-reported. - The researchers note that low mood may lead to more screen use rather than the reverse.

The student wants to present the study's finding while acknowledging a limitation the researchers raised. Which choice most effectively uses relevant information from the notes to accomplish this goal?

  1. A. Days with more screen time were reported as lower-mood days, though the researchers note that low mood may drive screen use rather than the other way round.Correct
  2. B. The study asked 500 adults to keep a diary for a month.
  3. C. Screen time lowers mood, according to a month-long diary study of 500 adults.
  4. D. Because everything was self-reported, the study found nothing reliable.

Answer: A. Days with more screen time were reported as lower-mood days, though the researchers note that low mood may drive screen use rather than the other way round.

Finding plus the researchers' own caveat about direction — choice A.

Why the other answers are wrong

B. The study asked 500 adults to keep a diary for a month.
Method only.
C. Screen time lowers mood, according to a month-long diary study of 500 adults.
The finding stated as a cause, with no limitation.
D. Because everything was self-reported, the study found nothing reliable.
The researchers raised the direction problem, not a claim that the study found nothing.
