Answer to Question 1

Answer: C

Answer to Question 2

Answer: Autism is characterized by poor social skills, poor communicative abilities, and impaired imagination. Several genes strongly contribute as causes for autism. Dietary factors can contribute to autism (PKU), and prenatal toxins can induce autism (thalidomide). Treatments are largely preventive in that pregnant women can avoid taking thalidomide or contracting rubella. There are no current biological therapies for autism, although it has been suggested that administration of the hormone oxytocin, which promotes pair bonding, may be of use with autistic children.
