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: Is childhood maltreatment associated with depression but not with hypochondriasis in later life?
Answer: The findings suggest a robust association of childhood maltreatment with depression but not with hypochondriasis. This result does not support etiological models of hypochondriasis which rely on childhood maltreatment as a risk factor for the development of this disorder.
[EX A]: yes

[EX Q]: Question: Does pTEN loss in biopsy tissue predict poor clinical outcomes in prostate cancer?
Answer: PTEN loss at the time of biopsy seems to predict time to development of metastasis, prostate cancer-specific mortality and, for the first time, castration-resistant prostate cancer and response to androgen deprivation therapy after radical prostatectomy. If confirmed by larger studies, this would support the use of PTEN loss as an early marker of aggressive prostate cancer.
[EX A]: yes

[EX Q]: Question: Do mKL1/2 and ELK4 co-regulate distinct serum response factor ( SRF ) transcription programs in macrophages?
Answer: I conclude that SRF utilizes MKL1/2 to fulfill steady state cellular functions, including cytoskeletal organization, and utilizes ELK4 to facilitate acute responses to external infection. Together, these findings indicate that SRF, along with its two cofactors, are important players in both cellular homeostasis and stress responses in macrophages.
[EX A]:
yes
