Answer:
It is ineffective because it does not provide a logical reason for opposing the counterclaim.
Explanation:
In the given claim, counterclaim, and rebuttal, the main issue discussed is that of allowing children to play video games. The claim made is that children become violent from playing violent games.
The counterclaim, on the other claim, presents that they are allowed to play any game they want "under adult supervision". The rebuttal then presents the idea that allowing children only gives them unnecessary authority.
The rebuttal presented is ineffective as it failed to provide any logical reasoning for opposing the counterclaim.
Thus, the correct answer is the third option.
