The sentence that needs more explanation in order to support the claim is "Also, studies show that boys become more flexible and nimble when they play with girls on the team."

The sentence that needs more of an explanation in order to support the claim is "Also, studies show that boys become more flexible and nimble when they play with girls on the team." This sentence makes a claim about the benefits of boys playing with girls on the same sports team, but it doesn't provide any further information or evidence to support this claim. In order for this sentence to be more convincing, it would need to explain the specific studies that show the increase in flexibility and nimbleness among boys when they play with girls. Providing details about the methodology, sample size, and results of these studies would strengthen the argument and provide more evidence for the claim that girls and boys should be able to play on the same sports team.
