Answer choices

  1. Wrong Flaw2% picked this

    relies on a sample that is likely to be unrepresentative of the population with which

    This describes the famous Sampling flaw, but this argument didn't move from thinking, "If it's true in these cases, then it's true in all cases." Both the evidence and the conclusion are talking about the same two populations: parents / educational psychologists

  2. Out of Scope: what children enjoy2% picked this

    takes for granted that parents do not enjoy the same sort of children's television shows

    The argument takes for granted that parents do not rate the educational value of children's television shows the same way that educational psychologists rate them

  3. Too Strong6% picked this

    takes for granted that the educational value of a television show should be the only consideration for a parent trying to decide whether

    Too Strong: the only Out of Scope: whether kid should watch The author didn't commit to any extreme assumption like "Educational value is THE ONLY thing to consider when deciding on shows for your kid". This argument isn't even about deciding on shows for your kid. It's only about whether parents can / can't trust their assessments of educational value.

  4. Correct75% picked this

    fails to rule out the possibility that parents' ratings of the shows based on their own enjoyment coincide closely with the educational psychologists'

    Why this is right

    Would it weaken the argument if ... parents' ratings coincide closely with educational psychologists' ? Definitely! The conclusion is implying, "if the psychologists are right, then the parents are wrong", but if both groups agree on the educational rating of shows, then that conclusion would be stupid.

    Skill tested: Flaw · how this choice captures the argument's function is the move to repeat next time.

  5. Too Strong: the only16% picked this

    takes for granted that educational psychologists are the only people who can judge the educational value of children's television shows with

    It's too strong to say the author assumes that educational psychologists are the only ones who can accurately judge educational value. This is a common Assumption trap on the test --- if it was the Only One Mentioned, then it's the Only One But it's also too strong to even say the author assumes that educational psychologists are one example of people who can accurately judge. The conclusion is a conditional that says, "If they psychologists' ratings are correct". The author has never endorsed the idea that the psychologists' ratings are, in fact, correct.
