QUESTION TYPE: Necessary Assumption
CONCLUSION: Autistic children can benefit from treatment earlier in life.
REASONING: A new test exists, which for the first time can accurately diagnose autism in children as young as 18 months old.
___________
- No accurate test would have been a necessary assumption, but it’s quite possible (inaccurate) tests existed.
- CORRECT. Yes. If this weren’t true, the conclusion is worthless, because the test does give false positives.
- Not necessary, the test only claims to diagnose children 18 months old.
- This may sound cruel, but the conclusion wasn’t concerned with the non-autistic, falsely identified children. They could be scarred for life and the conclusion about autistic children could still be correct.
- There could have been reliable evidence, yet still no accurate means of diagnosis.
