Roger: Reading a lot as a child causes nearsightedness— difficulty seeing things at a distance.

Louise disputes Roger’s claim by

A．demonstrating that an absurd conclusion would follow if Roger’s claim were accepted.

B．arguing that what Roger claims to be a cause of a given phenomenon is actually its effect.

C．using an analogy to expose a flaw in Roger’s reasoning.

D．pointing out that Roger’s claim is self-contradictory.

E．(E) attempting to demonstrate that Roger uses the term "nearsightedness" in an ambiguous way.
