Heavier = More?

Which one of the following most accurately expresses the conclusion drawn in the consumer advocate's argument?

Consumer advocate: Even if one can of fruit or vegetables weighs more than another, the heavier can does not necessarily contain more food. Canned fruits and vegetables are typically packed in water, which can make up more than half the weight of the can's contents. And nothing stops unscrupulous canning companies from including more water per can than others.

Answer: The heavier of two cans of fruit or vegetables does not necessarily contain more food than the lighter of the two cans contains.

The heavier one could just contain more water. This is our main point from the first sentence.

Decipher the Human Genetic Code?

Which one of the following most accurately expresses the conclusion of the ethicist's argument?

Ethicist: Robert Gillette as argued that because a thorough knowledge of genetics would enable us to cure the over 3,000 inherited disorders that affect humanity, deciphering the human genetic code will certainly benefit humanity despite its enormous cost. Gillette's argument is not persuasive, however, because he fails to consider that such knowledge might ultimately harm human beings more than it would benefit them.

Answer: Gillette's argument is unconvincing because it ignores certain possible consequences of genetic research.
