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.

Ex Input:
Question: Is visceral pleural invasion a significant prognostic factor in patients with a part-solid lung cancer?
Answer: VPI may not contribute to the prognosis of patients with part-solid nodules. Thus, upgrading of the TNM stage on the basis of VPI should be carefully considered in these patients.

Ex Output:
no


Ex Input:
Question: Do integrin-associated complexes form hierarchically with variable stoichiometry in nascent adhesions?
Answer: These observations suggest a working model for NA assembly whereby transient α-actinin-integrin complexes help nucleate NAs within the lamellipodium. Subsequently, integrin complexes containing kindlin, but not talin, emerge. Once NAs have formed, myosin II activity promotes talin association with the integrin-kindlin complex in a stoichiometry consistent with each talin molecule linking two integrin-kindlin complexes.

Ex Output:
yes


Ex Input:
Question: Is coxa profunda a useful radiographic parameter for diagnosing pincer-type femoroacetabular impingement?
Answer: Coxa profunda should be considered a normal radiographic finding, at least in females. Coxa profunda is a nonspecific radiographic finding, seen in a variety of hip disorders and asymptomatic hips. The presence of coxa profunda is neither necessary nor sufficient to support a diagnosis of pincer-type femoroacetabular impingement.

Ex Output:

no
