All insects have six legs. An object has the same property. Which statement is correct?
Answer and explanation
Correct answer: D. We cannot tell whether it is one of the insects
- Step 1: The first statement says that all insects have the property, not that only insects have it. Step 2. Other things may share the property, so no conclusion about the group follows. Answer: We cannot tell whether it is one of the insects. Why not the others: It must be one of the insects is what you get if you reverse the statement. It cannot be one of the insects is what you get if you deny without evidence. It is the largest of the insects is what you get if you invent extra facts.
