Given a passage with a question and an answer to that question, classify if the answer actually answers the question into 'yes' or 'no'. Output 'yes' if the answer answers the question and output 'no' if the answer does not answer the question.

Input: Consider Input: Question: Does mechanical ventilation with lower tidal volumes influence the prescription of opioids or sedatives?
Answer: Concerns regarding sedation requirements with use of lower V(T) are unfounded and should not preclude its use in patients with ALI/ARDS.

Output: no

Input: Consider Input: Question: Are antihelminthic benzimidazoles novel HIF activators that prevent oxidative neuronal death via binding to tubulin?
Answer: These studies demonstrate that tubulin-binding drugs can activate a component of the hypoxic adaptive response, specifically the stabilization of HIF-1 and its downstream targets. Tubulin-binding drugs, including antihelminthic benzimidazoles, also abrogate oxidative neuronal death in primary neurons. Given their safety in humans and known ability to penetrate into the central nervous system, antihelminthic benzimidazoles may be considered viable candidates for treating diseases associated with oxidative neuronal death, including stroke.

Output: yes

Input: Consider Input: Question: Is -blocker therapy associated with adverse outcomes in patients with pulmonary arterial hypertension : a propensity score analysis?
Answer: There was no statistically significant difference in long-term mortality between propensity score-matched pairs of PAH patients with and without -blocker use. These findings need further validation in prospective clinical trials.
Output: no
