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 peroxiredoxin 1 promote pancreatic cancer cell invasion by modulating p38 MAPK activity?
Answer: Prdx1 associates with the formation of membrane protrusions through modulation of the activity of p38 MAPK, which in turn promotes PDAC cell invasion.

Output: yes


Input: Consider 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.

Output: no


Input: Consider Input: Question: Do central adenosine A1 and A2A receptors mediate the antinociceptive effects of neuropeptide S in the mouse formalin test?
Answer: The above findings suggest that: (i) NPS evokes central antinociceptive effects by activating both A1 and A2A receptors during phase 1, but (ii) only the adenosine A2A receptor during phase 2 of the formalin test.


Output: yes
