Q46. Autism is a brain development disorder that impairs social interaction and communication and causes restricted and repetitive behavior, all starting before a child is three years old. The genetics of autism are complex, and it is generally unclear which genes are responsible. Autism affects many parts of the brain, but how this occurs is also poorly understood. It is strongly associated with agents that cause birth defects. Other proposed causes, such as childhood vaccines, are controversial, and the vaccine hypothesis lacks convincing scientific evidence. The number of people known to have autism has increased dramatically since the 1980s. Parents usually notice signs in the first two years of their child's life. Early cognitive behavioral intervention can help children gain self-care, social, and communication skills, but there is no cure. While fewer people with autism live independently after reaching adulthood, some become successful. An autistic culture has developed, with some members seeking a cure and others believing that autism is a condition rather than a disorder.It can be understood from the passage that autism:English — Passages — Question 46 of 56A. is caused by a childhood vaccine that affects the development of the brainB. is accepted as a condition rather than a disorder by all specialistsC. was a more prevalent disorder in the past than it is todayD. is characterized by abnormalities of behavior patternsPractice more English MCQs for entrance exam preparation on Examora.io.← Previous Question Next Question →
