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: Does in vivo gene transfer of endothelial nitric oxide synthase to carotid arteries from hypercholesterolemic rabbits enhance endothelium-dependent relaxations?
Answer: Adenovirus-mediated gene transfer of eNOS to carotid arteries of cholesterol-fed animals improves endothelium-dependent relaxation when an optimal viral titer is administered.

Output: yes


Input: Consider Input: Question: Are standard equations accurate in assessing resting energy expenditure in patients with amyotrophic lateral sclerosis?
Answer: We found that standard equations used to calculate energy expenditure were not valid for patients with ALS. Moreover, the majority of our patients were either overfed or underfed. As underfeeding can cause diaphragm impairment, and overfeeding can increase ventilatory load, indirect calorimetry should be considered in ALS patients to determine optimal caloric requirement.

Output: no


Input: Consider Input: Question: Does information-enhancement and goal setting techniques for increasing adaptive motivation and decreasing urge to drink alcohol?
Answer: The results show that sense of control can be experimentally induced. This finding has important clinical implications.


Output: yes
