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: Is arthrogenic muscle inhibition present in the limb contralateral to a simulated knee joint effusion?
Answer: Knee joint effusion results in ipsilateral but not contralateral impairment of quadriceps function. Rehabilitation protocols after knee joint injury should focus on ipsilateral neuromuscular and mechanical alterations that occur as the result of joint damage.
Example Output: no

Example Input: Question: Is reorganization of Azospirillum brasilense cell membrane mediated by lipid composition adjustment to maintain optimal fluidity during water deficit?
Answer: Azospirillum brasilense is able to perceive osmotic changes by changing the membrane fluidity. This effect is offset by changes in the composition of membrane phospholipid and FA, contributing to the homeostasis of membrane fluidity under water deficit.
Example Output: yes

Example Input: Question: Does transcription Factor KLF5 bound a Cyclin E1 Polymorphic Intronic Enhancer to Confer Increased Bladder Cancer Risk?
Answer: A polymorphic KLF5 binding site near the CCNE1 gene explains genetic risk identified through GWAS. Mol Cancer Res; 14(11); 1078-86. ©️2016 AACR.
Example Output:
yes
