D) contains a spelling error.
Answer:
D) Testing has shown that teenage boys between the ages of 15-18 sleep longer than teenage girls in the same age group.
Explanation:
The best way to revise this sentence is given in option D.
Option A lacks all necessary details, simply stating that males sleep longer than females. The research/testing, children's age, and the hours are not mentioned.
Option B feels like the second best, but a very important piece of information is missing - the specific age. Teenagers are children aged 13-19, and the difference between 13- and 19-year-olds is huge.
Option C also lacks information about the subjects' age.
Option D is also not ideal but feels the most complete. It doesn't mention how much longer exactly the boys sleep, but that detail isn't as important as the specific age is.
