Kris: Years ago, the chemical industry claimed that technological progress cannot occur without pollution. Today, in the name of technological progress, the cellular phone industry manufactures and promotes a product that causes environmental pollution in the form of ringing phones and loud conversations in public places. Clearly, the cellular industry must be regulated, just as the chemical industry is now regulated.

Terry: That's absurd. Chemical pollution can cause physical harm, but the worst harm that cellular phones can cause is annoyance.

D. questioning the strength of the analogy on which Kris's argument is based
E. rejecting Kris's interpretation of the term 'technological progress'
Answer: "D"
