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: Do manual Lymphatic Drainage and Active Exercise Effects on Lymphatic Function Translate Into Morbidities in Women Who Underwent Breast Cancer Surgery?
Answer: MLD and active exercise effects are equivalent with regard to morbidity. Minor changes in lymphatic function associated with either MLD or active exercises were not related to patients' symptoms or signs.
Example Output: no

Example 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.
Example Output: yes

Example Input: Question: Is assortative mating among Lake Malawi cichlid fish populations simply predictable from male nuptial colour?
Answer: We suggest that non-visual cues, such as olfactory signals, may play an important role in mate choice and behavioural isolation in these and perhaps other African cichlid fish. Future speciation models aimed at explaining African cichlid radiations may therefore consider incorporating such mating cues in mate choice scenarios.
Example Output:
no
