Nutritionist: Multivitamins are potent storehouses of antioxidants, substances that fight the oxidation process, which breaks down the body. Nonetheless, according to longitudinal studies—studies that follow subjects over the course of many years—those who take multivitamins every day have a decreased longevity. Clearly, if people want to live longer they should avoid antioxidants.

Which of the following is an assumption the argument relies on?

The use of antioxidants does not vary across different age groups.

The less often one takes multivitamins, the more one’s longevity increases.

The antioxidants found in vitamins do not differ from antioxidants found in other sources, such as food.

Antioxidants can confer health benefits that do not relate to longevity.

Antioxidants destroy free radicals, which are toxic to the body.
