I don't understand how answer A cast doubt on Passage B or bolsters the argument in passage a? The human population is not discussed in either passage. How is it relevant?

Hi saranash1.

Answer (A) does not refer specifically to human population, but rather populations of species generally. Author A talked about the threat to various species beginning in line 10. Author B largely dismissed this information, stating that for the most part, "none of the species highlighted..can be considered threatened in North America." Choice (A) supports Author (A) by stating that even if the threat to species is a localized problem now, such population reduction is often a precursor to widespread endangerment. This answer undermines Author (B), because its information shows that the kind of localized population issues he dismisses is often a precursor to the widespread endangerment he implies would be a problem.

Thanks,

Ron
