IMO option E
Conclusion - Banning fast food advertisements will do little to curb childhood obesity.
Authors proposal/ suggestion - The responsibility (what to eat/ eating habits) should fall on parents and not on the government.
NOTE: This is not the main conclusion of the argument.
Question -> Identify the weakner from the option choices.
To weaken, we need to find an option choice that suggests doubts the author's conclusion/ reasoning.
(A) Families are increasingly relying on the fast-food industry for financial reasons and will continue to frequent these establishments on their own terms, regardless of their children’s preferences.
This options choice says that banning advertisments has no effect and families will continue to consume fast foods. This is supporting the author's point of view about the BAN. Incorrect(B) Studies indicate that, generally speaking, adults tend to be more influenced by advertising than children.
Irrelevant, degree of comparison between Child and the Adults does not provide any information/ link about the effetiveness of the advertisements on the Child's eating habits. Incorrect(C) If children learn that adults are trying to limit their fast-food intake, they will want to consume fast food even more.
A tricky option choice. It talks about the author's proposal and not about the advertisements. This choice suggests that Banning advertisements will not lead to decrease in fast food intake and hence Strengthening the argument. A bad side effect of the ban. Incorrect(D) Those opposed to fast-food marketing geared toward children are welcome to buy airtime for their cause, too.
Irrelevant, does not link how airtime for a different cause would undermine author's opinion. Incorrect(E) Watching an advertisement has been shown to increase one’s desires for a product, particularly when the product is a food item.
Correct Watching an advertisement increases the desire, influencing the child to use/ purchase the product. By eliminating/ banning these advertisements, the influence is removed. Thereby, potentially impacting the childs obesity in a good way because now the child is not influenced to eat fast food.
