Passage

After the school introduced a quiet reading period, library visits increased and teachers reported fewer classroom interruptions in the afternoon.

Question

What can reasonably be inferred?

Answer

The quiet reading period may have improved students' focus later in the day.

Solution

1. The passage links the new reading period with more library visits and fewer interruptions.
2. These facts support a cautious inference about improved focus.
3. 'May have' preserves the uncertainty because the passage does not prove causation.
