Question

Is the sentence "Brianna dunked the delicious donut into the whipped cream dip; this dessert was her absolute favorite."

Option 1: True
Option 2: False

Answer 1

The argument that all desserts are low fat because some sweet foods are low fat is invalid, as exemplified by the counterexample of a buttercream cake, which is a sweet dessert that is not low in fat.

Step-by-step explanation:

The sentence "Brianna dunked the delicious donut into the whipped cream dip; this dessert was her absolute favorite." suggests a specific dessert preference, but does not logically argue the nutritional content of desserts. When reviewing the argument provided:

1. All desserts are sweet foods.
2. Some sweet foods are low fat.
3. So all desserts are low fat.

The conclusion that all desserts are low fat is invalid. This is demonstrated by the counterexample of a buttercream cake, which is a dessert known to be sweet yet it is not low in fat. Thus, the argument fails because it concludes that all members of a subset (desserts) have a characteristic (low fat) based only on some members of a broader set (sweet foods) having that characteristic, which is a logical fallacy.
