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 Input:
Question: Is hypothalamic damage associated with inflammatory markers and worse cognitive performance in obese subjects?
Answer: DTI detects obesity-associated hypothalamic damage associated with inflammatory markers and worse cognitive performance. This study highlights the potential utility of (1) as a surrogate marker of obesity-associated hypothalamic damage.

Ex Output:
yes

Ex Input:
Question: Does prolonged hemorrhagic shock impair regeneration of plasma coagulant masses in the rabbit?
Answer: Dilutional coagulopathy corrects spontaneously within hours. Normovolemic shock prolongs dilutional coagulopathy not by impairment of factor regeneration but because of further (internal) dilution due to plasma expansion. Rapid correction of dilutional coagulopathy is likely to necessitate cryoprecipitate administration.

Ex Output:
no

Ex Input:
Question: Does hepatitis B virus vaccination booster provide additional protection in adolescents : a cross-sectional school-based study?
Answer: HBV booster strategy at 15years of age was the main contributor to the unique age-related phenomenon of anti-HBs seropositivity rate and titer. No increase in HBsAg seropositivity rates within different age groups was observed. Vaccination with plasma-derived HBV vaccines in infancy provided higher anti-HBs seropositivity at 15-18 years of age. Overall booster response rate was 92.5% and indicated that intact immunogenicity persisted at least 15years after primary HBV vaccination in infancy. Booster vaccination of HBV did not confer additional protection against HBsAg carriage in our study.

Ex Output:
no
