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 iCAM-1 deficiency suppress host allosensitization and rejection of MHC-disparate corneal transplants?
Answer: Prolonged survival seen in MHC-mismatched grafts in ICAM-1-/- mice, along with a suppressed DTH response to donor alloantigens after transplantation, suggest that ICAM-1 is associated with recipient sensitization to MHC alloantigens.
Example Output: yes

Example Input: Question: Does oral contraceptive use by teenage women affect peak bone mass : a longitudinal study?
Answer: Oral contraceptive pill use by healthy, white, teenage females does not affect acquisition of peak bone mass.
Example Output: no

Example Input: Question: Is short-interval intracortical inhibition affected by varying visual feedback in an isometric task in biceps brachii muscle?
Answer: SICI was not altered by performing the same task with differing visual feedback. However, SICI decreased with increasing submaximal torque providing further evidence that SICI is one mechanism of modulating cortical excitability and plays a role in force gradation.
Example Output:
no
