Stimulus

In a study of the relationship between aggression and television viewing in nursery school children, many interesting interactions among family styles, aggression, and television viewing were found. High aggression occurred in both high-viewing and low- viewing children and this seemed to be related to parental lifestyle. High-achieving, competitive, middle-class parents, whose children in an organized, child-centered way, which included larger amounts of television viewing.

Answer choices

  1. Out of Scope: TV causes aggression6% picked this

    Low levels of television viewing often lead to high levels of

    The second sentence tries to make it seem like aggression does not correlate well with amount of TV viewing, but instead correlates well with parenting lifestyle. So this answer is pinning aggression on something different from the causal difference-maker the passage identified (TV viewing vs. parenting lifestyle).

  2. Correct82% picked this

    The level of aggression of a child cannot be predicted from levels of

    Why this is right

    This reinforces the causal difference-maker by saying, "since we know that parenting lifestyle seems to be predictive of aggression, level of aggression cannot be predicted by simply looking at [something else]." If we knew that someone's LSAT score was related to their chance of being admitted to Harvard, then we could say that "the chance that someone will be admitted to Harvard cannot be predicted from looking at their GPA alone".

  3. Unsupported Causality8% picked this

    If high-achieving, competitive, parents were more child-centered, their children would be

    This isn't too bad; it's just less provable than (B). It feels like it's acknowledging the causal difference-maker by saying, "If they did less of the thing that causes more aggression and more of the thing that causes less aggression, their kids would be less aggressive." The problem is that it borrows a subset of characteristics correlated with more aggression (it leaves out middle-class) and prescribes a subset of characteristics correlated with less aggression (it leaves out organized). Since we don't have any clear idea which part of high-achieving / competitive / middle-class is causally responsible for more aggression (if any) and since we don't know which part of organized / child-centered is causally responsible for less aggression (if any), it's pretty speculative for us to say what effect specific changes would have. Maybe as long as the parents are still competitive, their kids will be aggressive, whether the parents get more child-centered or not. Maybe as long as the parents are still disorganized, their kids will be aggressive, whether the parents get more child-centered or not.

  4. Too Strong: only when3% picked this

    High levels of television viewing can explain high levels of aggression among children only when the

    This messy data won't allow for us to conclude tightly drawn takeaways, like Parents child-centered ? high TV can't explain high aggression It's definitely possible that some child-centered parents could end up with high aggression kids because of the kids' high levels of TV viewing.

  5. Contradicted1% picked this

    Parental lifestyle is less important than the amount of television viewing in determining the

    The 2nd sentence seems to be establishing the opposite of this answer. High aggression is found in both high and low TV viewing (suggesting there's not a strong causal influence there), whereas aggression seemed to be related to parental lifestyle.
