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: 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: Do armband activity monitor data correlate with reported pain scores in patients receiving vertebroplasty?
Answer: Activity monitors can be used to objectively record changes in activity following vertebroplasty procedures. Patient-reported pain or disability scores do not correlate with activity monitor-measured activity or sleep metrics.

Ex Output:
no


Ex Input:
Question: Does bilateral L1 and L2 dorsal root ganglion block for discogenic low-back pain?
Answer: We conclude that blocks of this nociceptive pathway in humans using bilateral DRG blocks has no therapeutic value.

Ex Output:

yes
