Public health officials recently claimed that a new vaccination campaign led directly to a 20 percent decrease in seasonal influenza cases this winter. However, data from regional health clinics indicate that the reduction in flu cases occurred almost entirely in counties where strict sanitation protocols were introduced simultaneously. While vaccinations certainly provide individual protection against virus strains, the dramatic overall drop in transmission was primarily driven by improved hygiene practices rather than the vaccine rollout itself.
Which of the following best describes the roles played by the two boldfaced portions in the argument above?
- AThe first is the main conclusion of the argument; the second is a finding presented to support that conclusion.
- BThe first is a claim made by public health officials; the second is a counterexample intended to refute that claim.
- The first is evidence cited to challenge a rival claim; the second is the main conclusion that the argument advocates.Cevap
- DThe first is background information supporting the vaccination campaign; the second is a premise used to support a rival position.
- EThe first is an unstated assumption required by the argument; the second is a secondary finding derived from clinic data.
Cevap
The first boldfaced portion is evidence cited to challenge a rival claim, and the second is the main conclusion that the argument advocates.
The correct answer accurately reflects the structural flow: the first boldfaced sentence provides empirical evidence (regional clinic data) that challenges the initial claim made by public health officials, while the second boldfaced sentence asserts the main judgment/conclusion that the author seeks to establish.
