Question

Quizplus · Accepted Answer

Phenylketonuria can lead to mental retardation if not managed properly, but if Benji avoids consuming phenylalanine, he can have normal intelligence. The age of Benji's mother is not provided in the question and is therefore not relevant to this scenario. It is also not accurate to suggest that phenylketonuria would not surface until middle age.
