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 diffusion-tensor imaging implicate prefrontal axonal injury in executive function impairment following very mild traumatic brain injury?
Answer: Impaired executive function following mTBI is associated with axonal injury involving the DLPFC.

Output: yes


Input: Consider Input: Question: Is a high body mass index in esophageal cancer patients associated with adverse outcomes following esophagectomy?
Answer: A high BMI is not associated with increased overall morbidity following esophagectomy; moreover, it is associated with decreased incidence of chylothorax. The better overall survival in patients with high BMI compared with those with low BMI might be due to a relatively low pathological stage. A high BMI should therefore not be a relative contraindication for esophagectomy.

Output: no


Input: Consider Input: Question: Is subclinical onychomycosis associated with tinea pedis?
Answer: Dermatophyte fungi may be isolated from normal-appearing toenails. The presence of dermatophytes in this situation is strongly associated with the presence of tinea pedis. Subclinical dermatophyte in the nail plate may serve as a reservoir for ongoing local infection.


Output: yes
