Question

Which word is correct
Since
Because
Additionally
Therefore

Answer 1

The most appropriate word to fill in the blank in this context is "therefore."

The completed sentence would read: "Research shows that teenagers require at least eight to nine hours of sleep each night; therefore, schools should consider implementing later start times so teens can get the sleep that they need."

This choice effectively shows a cause-and-effect relationship between the need for more sleep and the suggestion of later school start times.
