Passage Summary: Critics say calculators make kids bad at math, but they're wrong because people have been complaining about new technology since the invention of the alphabet.

Conclusion: The claim that calculators will damage students' understanding of mathematical principles is false.

Reasoning: Similar accusations have been made about every new information technology in history, such as ancient Greek concerns that writing would destroy memory.

Analysis: This argument falls into the trap of assuming that because people were wrong about a similar issue in the past, they must be wrong about this specific issue now. Just because the Greeks were overreacting about the 'dangers' of writing doesn't mean modern critics are overreacting about calculators. The author is dismissing a specific concern based on a historical pattern rather than addressing the actual merits of the critics' claims. Look for an answer that points out this failure to address the specific case at hand.
