Teenagers tend to fall asleep later and wake later than younger children, a pattern that scientists link to changes in the body's internal clock during adolescence. In some countries, schools have moved the start of the day by an hour. Early reports describe fewer students arriving late and fewer who fall asleep in class. However, a later finish can clash with sports practice and with parents' working hours, so not every community finds it easy to change. Some experts suggest a smaller step: keep the start time but avoid scheduling exams in the first period.

Answer and explanation

Correct answer: B. Early reports suggest benefits, but communities may find the change hard to start

  1. Step 1: The passage gives early positive reports and practical obstacles. Step 2. Only the option 'Early reports suggest benefits, but communities may find the change hard to start' keeps both. Answer: Early reports suggest benefits, but the change may be hard. Why not the others: The others claim more than the passage says.
