Answer:
The final sentence of the excerpt is a part of a strong argument that is referred to as a counterclaim.
Explanation:
A counterclaim simply means an opposing argument. A counterclaim is used by an individual to reject something that was said earlier.
A counterclaim is used when one doesn't support a particular thing and then says something that is different.

In conclusion, the above analysis illustrates a counterclaim.
