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.

Example Input: Question: Does pEEP ventilation cause humorally mediated cardiac output depression in pigs?
Answer: As humorally mediated negative inotropism during PEEP ventilation has earlier been demonstrated in dogs, the results suggest that this mechanism might be species-dependent.
Example Output: no

Example Input: Question: Are screening tests enough to detect hemineglect?
Answer: Hemineglect may not be recognized with single screening tests commonly used. The use of a standard battery is recommended to improve diagnostic sensitivity in individuals with various subtypes of hemineglect.
Example Output: no

Example Input: Question: Do paraoxonase 1 deficiency and hyperhomocysteinemia alter the expression of mouse kidney proteins involved in renal disease?
Answer: Our findings suggest that excess Hcy is toxic because it deregulates the expression of proteins involved in diverse cellular processes-from lipid, protein, carbohydrate, and energy metabolisms to detoxification and antioxidant defenses-that are essential for normal kidney homeostasis. Dysregulation of these processes can account for the involvement of HHcy and reduced Pon1 in kidney disease. Our findings also show that Pon1 plays an important role in maintaining normal kidney homeostasis.
Example Output:
yes
