Question

read the excerpt from an argument in favor of having classes start later.
as children get older, they go to bed later. ____, their classes begin earlier. ____, they are increasingly sleep deprived.
which transitional words or phrases should be used to clarify the relationships between the ideas?
○ but; however
○ yet; as a result
○ however; in addition
○ for example; therefore

Explanation:

1. First blank: The first sentence states kids go to bed later, the next says classes start earlier—this is a contrasting relationship. "Yet" correctly signals this contrast.
2. Second blank: The earlier classes + later bedtimes lead to sleep deprivation—this is a cause-and-effect relationship. "As a result" correctly signals this consequence.
3. Eliminating other options:

• "But; However" uses two contrast words, which does not fit the second cause-effect link.
• "However; In addition" uses a contrast word and an additive word, which does not fit the second cause-effect link.
• "For example; Therefore" uses an example word, which does not fit the first contrasting link.

Answer:

Yet; As a result
