Why the other options are wrong:

• evidence that virtual reality causes autism.: Autism characterizes the children receiving support; virtual reality is not said to cause it.
• a physical training programme for autistic children.: Breathing and relaxation support coping with fears rather than a programme of physical training.
• virtual reality to treat malaria.: Malaria is not discussed; the facility addresses anxiety and phobias.

Correct Answer: anxiety.

Why this is correct: Jeremy Parr states that about half of children on the autism spectrum have anxiety. Anxiety is the condition attached to that proportion in the report.

Why the other options are wrong:

• intolerance.: Intolerance is not the condition Parr identifies for about half of the children. He names anxiety.
• joy.: Joy is not the condition linked to the half-of-children figure. The statement concerns anxiety.
• indifference.: Indifference is not the condition Parr names; the reported condition is anxiety.

Correct Answer: cope with tough situations.

Why this is correct: The report says the safe, controlled environment helps children learn to cope with tough situations, supported by a psychologist.

Why the other options are wrong:

• avoid all medication permanently.: The report does not claim children can stop all medication permanently.
• cope with any problem without help.: A psychologist supports the children, and the report does not claim they can solve every problem without help.
• increase their physical strength.: The aim is coping with feared situations, not increasing physical strength.

Correct Answer: virtual situation.

Why this is correct: The psychologist can increase the intensity of the situation as children overcome their fears. The pigeon example shows the virtual scene becoming more challenging.

Why the other options are wrong:

• medication.: The adjustable intensity concerns a virtual situation, not medication.
• laser.: No laser intensity is adjusted in the described facility.
• physical exercise.: The feared scene becomes more challenging; the report does not describe intensifying physical exercise.

Correct Answer: funding

Why this is correct: Carol Povey asks for funding if results continue to be positive, so more people can access the treatment.

Why the other options are wrong:

• medicine: Her request is for funding to improve access, not medicine.
• more sample results: Positive results are the condition for the request, not the resource to make available.
• clinical trials: Trials appear earlier, but the quoted request is for funding to broaden access.
