Final answer:
The rough draft of the student's conclusion discusses the benefits of year-round schooling on student achievement. Adding a sentence that highlights the advantage of having more time to master new concepts would improve the conclusion the most.
Step-by-step explanation:
The rough draft of the student's conclusion is about year-round schooling and its benefits on student achievement. The student argues that year-round schooling reduces the need to cram information into a nine-month period, eliminates long breaks to minimize learning loss, and helps students retain more knowledge. The conclusion also mentions that other countries have implemented year-round school schedules and students in these schools consistently score higher on certain assessments compared to students in traditional schools.
If added after sentence 3, the sentence 'Because students would not need to spend so much time reviewing previously covered material, they would then have more time to master new concepts.' would most improve the conclusion. It supports the idea that year-round schooling allows students to spend less time reviewing old material and more time mastering new concepts, which ultimately improves their learning.
