Consumer Advocate: The new soft drink, Mango Paradise, contains at least 2.5% of Ephedra, a chemical supplement that stimulates the activity of the nervous system but may also result in serious cardiac problems. Therefore, this drink is harmful to consumer health and should be banned from distribution in our state.

Which of the following is an assumption made by the consumer advocate?
(A) The new soft drink will soon be introduced into mass production.
(B) Consumers are unlikely to enjoy the taste of Mango Paradise because of the high amount of Ephedra contained in the drink.
(C) Any drink that contains at least 2.5% of Ephedra is harmful to consumer health.
(D) The Consumer Advocate is not affiliated with the producer of Mango Paradise.
(E) Most consumers who drink Mango Paradise will eventually experience serious cardiac problems.

Why is E incorrect? what makes C a better answer than E?

Thanks in advance.

The sentence doesnt talk about the number of ppl who might suffer from cardiac arrest

Yep, as far as E is concerned, nothing in the argument gives us any idea of the number or proportion of people who might be affected.

The first sentence tells us one thing about the drink: it "contains at least 2.5% of Ephedra." The author then concludes "therefore" this drink is harmful. The author must be assuming that the only given piece of info is the problem - the threshold ("at least 2.5%") is the problem.
