A study of twenty overweight men revealed that each man experienced significant weight loss after adding SlimDown, an artificial food supplement, to his daily diet. For three months, each man consumed one SlimDown portion every morning after exercising, and then followed his normal diet for the rest of the day. Clearly, anyone who consumes one portion of SlimDown every day for at least three months will lose weight and will look and feel his or her best.

Which one of the following is an assumption on which the argument depends?

Try to prephrase an answer.

Countinue

The evidence is based on men who took the product and exercised every day; the conclusion is about people who only took the product. For that conclusion to be valid, the author must be assuming that in the study it was the product, and not the exercise, that made the men lose weight. Having that as your prephrase will help you evaluate the answer choices.
