Final answer:
The conclusion 'So all desserts are low fat' is false due to a logical fallacy; the correct conclusion from the premises provided should be that some desserts may be low fat, but not all. Therefore, the given statement is FALSE. Therefore, the correct option is B.
Step-by-step explanation:
The statement presented in Argument 2 is a logical syllogism, which involves a sequence of statements that logically follow from one another. In this case, the argument presented is flawed. This is because the first premise states that all desserts are sweet foods, and the second premise claims that some sweet foods are low fat. However, the conclusion 'So all desserts are low fat' incorrectly assumes that all members of the first group (desserts) have the characteristic of the subgroup mentioned in the second premise (low-fat sweet foods).
Correct reasoning from these premises would allow us to conclude that some desserts may be low fat, but not necessarily all. This type of logical error is known as a faulty generalization or a hasty generalization.
