Final answer:
A specific counterexample to the definition is bats, which are warm-blooded mammals that are not humans. Another counterexample is the platypus, which is a mammal but not warm-blooded. Thus, the definition is both unnecessarily specific and insufficiently broad.
Step-by-step explanation:
Counterexample to the Definition
The definition states that a human is warm-blooded. However, there is a specific, actual counterexample to this definition. Bats are warm-blooded mammals but are not humans. This example shows that the definition is unnecessarily specific because it excludes other warm-blooded animals like bats.
Another counterexample that shows the definition is insufficiently broad is the platypus. The platypus is a mammal but is not warm-blooded. Therefore, it does not meet the condition of being a human according to the definition. This example demonstrates that the definition does not encompass all possible cases.
Counterexample Conclusion:
The definition is both unnecessarily specific and insufficiently broad.
