Question

Quizplus · Accepted Answer

The fact that the brains of children with the diagnosis of autism spectrum disorder do not appear to develop normally during adolescence suggests that the disorder has a biological basis. This finding supports the idea that autism is a biological disorder. Choice A is also a possible answer because the fact that the concordance rate for the disorder is the same for identical and fraternal twins suggests that genetic factors play a significant role in the development of the disorder, which is a biological factor. However, choice D is a better answer because it specifically points to abnormal brain development, which is a key feature of the disorder. Choices B and C are not the best choices because they do not provide strong evidence that supports the idea that autism spectrum disorder is a biological disorder.
