Text 1: Public-health researcher Park argues that needle-exchange programs reduce HIV transmission among people who inject drugs. Decades of evidence from cities that have implemented exchanges show falling infection rates without measurable increases in drug use.
Text 2: Public-health researcher Singh agrees with Park's evidence on HIV but argues that needle exchanges are a partial solution. Without accompanying access to treatment, housing, and mental health care, she contends, exchanges can only manage one risk among many. The evidence supports needle exchanges; it does not support treating them as sufficient policy.
Both authors would most likely agree that
- Acheck_circle

- B
needle exchanges have no measurable health effects.
- C
needle exchanges are sufficient by themselves to address all related public-health problems.
- D
needle exchanges encourage drug use.
Explanation
Both accept the HIV-reduction evidence; they differ on whether exchanges are sufficient. A is shared. B, C, and D contradict at least one author.
