Stimulus

The labeling of otherwise high-calorie foods as "sugar-free," based on the replacement of all sugar by artificial sweeteners, should be prohibited by law. Such a prohibition is indicated because many consumers who need to lose weight will interpret the label "sugar-free" as synonymous with "low in calories" and harm themselves by building are well aware of this tendency on the part of consumers.

The question
11.

Which one of the following, if true, provides the strongest basis for challenging the conclusion

Answer choices

  1. Unclear Impact11% picked this

    Food manufacturers would respond to a ban on the label “sugar-free” by reducing the calories in sugar-free products by enough to be able to

    We want to say that this ban would be a bad idea, and this answer presents a consequence of enacting the ban. Is it a negative consequence? Hard to tell -- it doesn't sound inherently bad for manufacturers to reduce the calories in their products..

  2. Correct63% picked this

    Individuals who are diabetic need to be able to identify products that contain no sugar by reference to product labels that expressly state

    Why this is right

    This presents a strong reason against banning the "sugar-free" label, as it overlooks how essential this labeling is for other dietary needs. It offers an important consequence that banning would negatively impact people who rely on this information for health reasons, thereby challenging the conclusion. When authors conclude we "should" do something, they assume the upsides outweigh the downsides, and this is presenting a big ol' downside of banning sugar-free labels.

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

  3. No Impact / Too Weak4% picked this

    Consumers are sometimes slow to notice changes in product labels unless those changes are

    It's very unlikely this would be correct, given its puny strength. It says "there's was at least one case in which a product label change wasn't well advertised and consumers were slow to notice it". We can't argue, "We shouldn't ban these labels, because there's a chance that some consumers wouldn't even notice that we removed the label." That's not a compelling downside.

  4. No Impact3% picked this

    Consumers who have chosen a particular weight-loss diet tend to persist with this diet if they have been warned not

    This doesn't have anything to do with upsides or downsides of having this sugar-free label. This fact about dieters applies the same to either scenario.

  5. Irrelevant Comparison19% picked this

    Exactly what appears on a product label is less important to consumer behavior than is the relative visual prominence of the different pieces

    Discussing the importance of the label's layout or prominence relative to other information doesn't directly challenge the necessity or impact of having the "sugar-free" label in itself. This point is tangential to the prohibition debate. We're trying to decide whether or not "sugar-free" should be one of the pieces of information on the product. We can worry about graphic design layout later.
