Question:

Read the passage and answer the question. A team of neuroscientists in 2023 asked a simple question: does a short nap after studying actually help you remember? They gave sixty volunteers a list of forty unfamiliar word pairs to memorise in the morning. Half the group then took a ninety-minute nap in a quiet laboratory room while their brain activity was monitored; the other half stayed awake watching a documentary. That evening, everyone was tested on the word pairs. The nappers recalled on average nine more pairs than the non-nappers, and the improvement was largest in those whose naps contained the most slow-wave sleep. The researchers concluded that the sleeping brain replays new information and files it into long-term storage, a process that cannot happen as effectively while we are awake and taking in new distractions. The 2023 experiment described in the passage found that

volunteers who napped after learning recalled more word pairs than those who stayed awake

watching a documentary improved memory more than taking a nap

slow-wave sleep had no measurable effect on recall scores

the volunteers remembered the word pairs equally well whether or not they slept

Correct Answer: volunteers who napped after learning recalled more word pairs than those who stayed awake

The passage reports that the nappers recalled on average nine more word pairs than the non-nappers, with the biggest gains linked to slow-wave sleep.
