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 extended pattern prostate biopsy minimize the volume-grade bias in prostate cancer detection?
Answer: Although more high grade cancers are detected with extended pattern biopsy, there is no differential upgrading with respect to prostate volume. Based on these observations extended prostate sampling in trials of agents that decrease prostate volume would have minimal impact on volume-grade associations.
[EX A]: no

[EX Q]: Question: Does slower infusion of metoclopramide decrease the rate of akathisia?
Answer: Slower infusion of metoclopramide reduces the incidence of akathisia.
[EX A]: yes

[EX Q]: Question: Do amyloid and APOE 4 interact to influence short-term decline in preclinical Alzheimer disease?
Answer: Clinically normal individuals who are APOE 4+ and have high A showed the highest cognitive decline. These results suggest that A and APOE 4 are not redundant contributors of decline in aging but rather interact to promote decline during the short follow-up period examined in this study. Longer follow-up periods will be essential to fully elucidate the influence of Alzheimer disease risk factors on cognitive decline in aging.
[EX A]:
yes
