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.

Example Input: Question: Does clinical evaluation of pazopanib eye drop versus ranibizumab intravitreal injections in subjects with neovascular age-related macular degeneration?
Answer: Pazopanib was well tolerated. Daily pazopanib eye drops in neovascular AMD subjects did not result in therapeutic benefit beyond that obtained with ranibizumab alone.
Example Output: yes

Example Input: Question: Does acute ethanol always affect delay discounting in rats selected to prefer or avoid ethanol?
Answer: Our data indicate that in these lines of animals, alcohol preference or avoidance has no impact on delay discounting following acute ethanol exposure. It is possible that other genetic models or lines may be differentially affected by alcohol and exhibit qualitatively and quantitatively different responses in delay discounting tasks.
Example Output: no

Example Input: Question: Are asthma , allergy , and airway hyperresponsiveness linked to the beta ( 2 ) -adrenoceptor gene?
Answer: These results indicate that asthma, allergy, and methacholine airway hyperresponsiveness are not linked to a dominant beta(2)-adrenoceptor gene with strong effect in these eight families with an inherited pattern of asthma.
Example Output:
no
