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: Do differential behavior patterns in cynomolgus monkey Macaca fascicularis in home cage in response to human gaze?
Answer: These results indicate that, even in their home cage, monkeys display a heightened level of awareness when gazed upon by a human observer, suggesting that human gaze may elicit emotional reactions. Further, under the human gaze, distinct behavioral subpatterns were apparent within the monkey cohort in our study, indicative of subgroups within the cohort.
[EX A]: yes

[EX Q]: Question: Does increased endometrial thickness on the day of human chorionic gonadotropin injection adversely affect pregnancy or implantation rates following in vitro fertilization-embryo transfer?
Answer: No adverse effects of a thickened endometrium were demonstrated on implantation, pregnancy, or abortion rates in the first IVF-ET cycle. These findings fail to corroborate with those of Weissman et al. and support those of Yakin et al.
[EX A]: no

[EX Q]: Question: Are common variants in 8q24 associated with risk for prostate cancer and tumor aggressiveness in men of European ancestry?
Answer: Although this study does not directly confirm associations of the three specific SNPs (cited above), it corroborates reported signals of association in 8q24 reaffirming that genetic variation on 8q24 influences susceptibility to PC in men of European ancestry. Although our study did not confirm the allelic association of rs1447295, meta-analysis of this SNP provided support to previous reported associations. Further, this study implicates the 8q24 region with aggressive forms of PC.
[EX A]:
yes
