Answer choices

  1. No Impact3% picked this

    There are other products on the market that are advertised as providing fiber as

    The existence of other fiber supplement products does not address whether the advertised claim about the 44 percent fiber content is misleading. This option doesn't influence whether the actual fiber content per pill compares to the recommended daily intake.

  2. No Impact3% picked this

    Nutritionists base their recommendation on medical findings that dietary fiber protects against some

    This choice is about why nutritionists recommend fiber, which doesn't directly relate to whether the advertisement misleads by focusing on the percentage of fiber. Understanding the health benefits of dietary fiber is useful, but doesn't show if the advertising claim misleads.

  3. No Impact0% picked this

    It is possible to become addicted to some kinds of advertised pills, such as sleeping

    While addiction to certain pills is a concern, it does not relate to the claim about 44 percent fiber being misleading. This choice discusses addiction potential generally, not the fiber content or nutrient claims.

  4. No Impact9% picked this

    The label of the advertised product recommends taking 3 pills

    Recommendation for dosage (taking 3 pills every day) is still not addressing whether the actual fiber content suffices to meet recommendations. Without knowing how much fiber is in each pill, this information doesn't show the claim is misleading.

  5. Correct84% picked this

    The recommended daily intake of fiber is 20 to 30 grams, and the pill

    Why this is right

    If the pill contains only one-third of a gram of fiber, this means three pills are necessary to get just one gram of fiber. Since the recommended daily intake is 20 to 30 grams, even taking multiple pills daily barely meets the recommendation. This contrasts misleadingly with the attention given to the "44 percent fiber" claim. By showing that the actual fiber per pill is far from enough to meet the daily recommendation, we see how the advertisement misleads by drawing focus solely to the percentage rather than the total grams provided by the dosage. The pill is "high in fiber" from a percentage standpoint (44%, wow!) but low in fiber from an absolute standpoint (you'd need 60-90 pills a day to hit your fiber goals).
