Evaluate Speaker's Argument and Evidence Practice Test

In a hallway interview for the school news, a student says: “We should require everyone to wear school uniforms. If we don’t, fashion competition will get worse, then students will spend all their time shopping, then grades will drop, and soon nobody will care about learning at all. Uniforms are the only way to stop this chain reaction.”

What logical fallacy best describes the student’s reasoning?

In a short campaign speech, Diego says: “Vote for me for class president because I’ll improve school spirit. My opponent can’t be trusted—he got detention in sixth grade. Also, I have great ideas like more pep rallies and a spirit-week theme day. Since he got detention, his plans must be bad, and mine must be better.”

Which statement best evaluates Diego’s reasoning?
