Passage Summary: Since we turned wolves into dogs by picking the calmest ones to breed, the author thinks we can do the exact same thing with every other animal in existence.

Conclusion: Every animal species can, in theory, be bred to become domesticated.

Reasoning: Domesticated species like dogs were created by selectively breeding the tamest individuals of a wild species, such as wolves, over many generations.

Analysis: The argument makes a sweeping generalization based on a single successful example. To weaken this, look for an answer that suggests the 'wolf-to-dog' model isn't universal. Perhaps some species simply do not have any 'tame' individuals to begin with, or their biological makeup is fundamentally resistant to the changes required for domesticity. The jump from 'it worked for wolves' to 'it works for everything' is a massive logical gap that is ripe for attack.
