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: Do divergent growth strategies between red algae and kelps influence biomechanical properties?
Answer: We propose that divergent patterns in the distribution of material properties along blades may have different consequences for the performance of kelps and red algae. The positioning of younger tissues at the blade base for kelps may enable these species to attain larger body sizes in wave-swept habitats.
Example Output: yes

Example Input: Question: Do elevated S100B levels correlate with the severity of encephalopathy during sepsis?
Answer: In severe sepsis, an increase in S100B does not allow the physicians to distinguish patients with severe impairment of consciousness from those with milder derangements or to prognosticate neurological recovery.
Example Output: no

Example Input: Question: Does gene transfer of calcitonin gene-related peptide suppress development of allograft vasculopathy?
Answer: The expression of CGRP effectively suppressed the development of allograft vasculopathy and encroachment by lymphocytes and inflammatory cells. This reduced the levels of VCAM-1 to inhibit apoptosis induced by iNOS; thus, the tissue of the allografted vessel was protected and rejection was averted.
Example Output:
yes
