Hi ivan.99!

To summarize Susan's response to Yuriko, she suggests an alternate cause, different from the one given by Yuriko.

Yuriko suggests that it was the legislation/campaign to educate parents that accounts for the 30% increase in vaccinations. Susan responds by indicating that most of the vaccinations opened right after the city opened neighborhood health clinics--so she is suggesting this is an alternate cause that instead accounts for the increase in vaccinations. Indeed, not only did most vaccinations occur right after these clinics opened, this was also "before the vaccination campaign really got going." This is why answer choice (B) is correct. By providing an alternate cause, she weakens the force of evidence that Yuriko uses in support of her conclusion.

Answer choice (E) states that Susan "presents evidence to suggest that vaccination campaigns are usually ineffective." Susan doesn't make a claim about vaccination campaigns in general, or "usually." Rather, her claim is limited to the specific city that Yuriko is discussing alone. She doesn't generalize beyond that.
