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: Does bacillus anthracis S-layer protein BslA bound to extracellular matrix by interacting with laminin?
Answer: These data demonstrated that laminin is a ligand for BslA.

Ex Output:
yes


Ex Input:
Question: Do athletes Condition Inspired Air More Effectively than Nonathletes during Hyperpnea?
Answer: This study shows no evidence of improved capacity to condition inspired air in endurance athletes, which could have suggested an increased bronchial blood flow or another adaptive mechanism. The absence of an adaptive mechanism could therefore contribute to airway damage observed in athletes in allowing colder but mainly dryer air to penetrate deeper in the lung.

Ex Output:
no


Ex Input:
Question: Does miR-20a-5p repress multi-drug resistance in osteosarcoma by targeting the KIF26B gene?
Answer: In addition to providing mechanistic insights, our study revealed that miR-20a-5p and KIF26B contribute to OS chemoresistance and determined the roles of these genes in this process, which may be critical for characterizing drug responsiveness and overcoming chemoresistance in OS patients.

Ex Output:

yes
