Question ID:PT41 S3 Q17 Passage:Reporter:  A team of scientists has recently devised a new test that for the first time accurately diagnoses autism in children as young as 18 months old. When used to evaluate 16,000 children at their 18-month checkup, the test correctly diagnosed all 10 children later confirmed to be autistic, though it also wrongly identified 2 children as autistic. Autistic children can therefore now benefit much earlier in life than before from the treatments already available.  Stem:Which one of the following is an assumption on which the reporter's argument depends? Correct Answer Choice:BChoice A:No test intended for diagnosing autism at such an early age existed before the new test was devised. Choice B:A diagnostic test that sometimes falsely gives a positive diagnosis can still provide a reasonable basis for treatment decisions. Choice C:The new test can be used to evaluate all children, regardless of the level of development of their verbal skills. Choice D:Those children incorrectly identified as autistic will not be adversely affected by treatments aimed at helping autistic children. Choice E:There was no reliable evidence that autism could affect children so young until the advent of the new test.
