Question

read - aloud of passages
in passage 1, the author uses evidence about academic research to show that:
(1 point)

• year - round school always improves student performance.
• academic results are mixed and not guaranteed.
• students prefer short breaks to long ones.
• families benefit financially from shorter breaks.

Explanation:

To solve this, we analyze each option:

• "Year - round school always improves student performance" uses "always", which is too absolute. Academic research on year - round schooling usually doesn't support such a universal claim.
• "Academic results are mixed and not guaranteed" is consistent with typical research on educational models (like year - round schooling). Different studies show varying results, so outcomes aren't guaranteed.
• "Students prefer short breaks to long ones" – the question is about what the author shows with academic research on year - round school (relating to performance/results), not student preferences for break lengths.
• "Families benefit financially from shorter breaks" – the focus of the question is on academic research related to student performance (implied by the context of year - round school and academic results), not family finances.

Answer:

B. Academic results are mixed and not guaranteed.
