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 dual tasking during postural stepping responses increase falls but not freezing in people with Parkinson 's disease?
Answer: For people with PD and FoG, forward falls may not always be caused by FoG, particularly under attention-distracting conditions.
Example Output: yes

Example 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 -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.
Example Output: yes

Example Input: Question: Is two hour mean GH superior to basal GH for the follow-up of acromegalic patients treated with Octreotide LAR?
Answer: There was no benefit to perform GH curves with the present protocol. It may be due to our established outpatient follow up protocol. The use of more complex protocols and the cost of multiple GH assays should be acknowledged, and probably reserved for patients with basal GH levels between 1 and 5 microg/L with discordant GH and IGF-I.
Example Output:
no
