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 Q]: Question: Does a shoe insole delivering subsensory vibratory noise improve balance and gait in healthy elderly people?
Answer: This study provides proof of concept that the application of the principle of stochastic resonance to the foot sole sensory system using a new low-voltage piezoelectric technology can improve measures of balance and gait that are associated with falls. Effective vibratory noise amplitudes range from 70% to 85% of the sensory threshold and can be set once daily.
[EX A]: yes

[EX Q]: Question: Do why social workers implement decisions to remove children at risk from home?
Answer: Further study is required to examine the generalizability of these findings to other countries, to understand better the reasons for the non-implementation, and to follow-up on the consequences of the non-implementation.
[EX A]: no

[EX Q]: Question: Are microcirculatory perfusion and vascular reactivity altered in post cardiac arrest patients , irrespective of target temperature management to 33 °C vs 36 °C?
Answer: In this relatively small sample size study microcirculatory blood flow and vascular reactivity did not differ nor change between TTM33 and TTM36.
[EX A]:
yes
