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: Are arterial stiffness and central arterial wave reflection associated with serum uric acid , total bilirubin , and neutrophil-to-lymphocyte ratio in patients with coronary artery disease?
Answer: N/L ratio and serum UA and TB levels might be used to risk-stratify patients with respect to arterial stiffness in CAD patients, especially in the presence of ACS.
Example Output: yes

Example Input: Question: Does external laryngeal manipulation improve the intubation success rate by novice intubators in a manikin study?
Answer: In this pediatric manikin study, ELM performed by novice intubators improved laryngeal view, but lengthened the duration of intubation and did not improve intubation success rate.
Example Output:
no
