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: Is mRNA expression of RRM1 , ERCC1 and ERCC2 associated with chemosensitivity to cisplatin , carboplatin and gemcitabine in human lung cancer cell lines?
Answer: These in vitro results suggest that further studies are needed to evaluate the expression of the RRM1, ERCC1 and ERCC2 genes as predictive biomarkers for sensitivity to platinum agents and gemcitabine.

Output: no

Input: Consider Input: Question: Is the G-308A variant of the Tumor Necrosis Factor-alpha ( TNF-alpha ) gene associated with obesity , insulin resistance and body fat distribution?
Answer: Our study did not detect any significant association of the G-308A TNFalpha polymorphism with obesity or with its clinical and metabolic abnormalities in this population. Our data suggests that, in our population, the G-308A TNFalpha polymorphism is unlikely to play a major role in the pathogenesis of these conditions.

Output: no

Input: Consider Input: Question: Does c-reactive protein estimation improve accuracy in the diagnosis of acute appendicitis in pediatric patients?
Answer: The sensitivity and PPV of WBC were better than CRP alone, or in combination with WBC. We conclude that CRP does not aid in the diagnosis of appendicitis. Simple appendicitis was seen in spite of normal WBC and CRP.
Output: no
