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.

Input: Consider Input: Question: Do fat mass and obesity-associated gene polymorphisms affect metabolic response to hormone therapy in healthy postmenopausal women?
Answer: The presence of fat mass and obesity-associated gene risk variants in healthy early postmenopausal women does not adversely affect their response to hormone therapy.

Output: no


Input: Consider Input: Question: Does bone mineral density vary as a function of the rate of joint space narrowing in the hip?
Answer: Patients with a rapid rate of JSN of the asymptomatic hip after unilateral THR are characterized by elevated local and remote BMD. The local elevation in BMD implies that increased local bone density may contribute to or serve as a marker for increased risk of development of OA (assuming that JSN can be used as a predictive marker). The presence of elevated BMD in the spine suggests that there are systemic as well as local aspects of OA pathogenesis, at least in patients with one THR and rapid JSN in the contralateral hip.

Output: yes


Input: Consider Input: Question: Is [ A single positive prostatic biopsy out of six systematic biopsies correlated with the intracapsular nature of the tumor on an individual level ]?
Answer: A single positive prostatic biopsy out of six systematic biopsies is a useful predictive factor of local extension, but, in the individual patient, does not guarantee favourable histopathological characteristics of the tumour, nor a favourable course of the disease.


Output: no
