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: 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.

Output: yes

Input: Consider Input: Question: Are proliferation of colo-357 pancreatic carcinoma cells and survival of patients with pancreatic carcinoma altered by insulin glargine?
Answer: Regular human insulin and insulin glargine may be used to treat diabetes in patients with pancreatic cancer.

Output: no

Input: Consider Input: Question: Does predrilling improve the pullout strength of external fixator pins : a biomechanical study?
Answer: Single-cortex pin placement, osteoporotic bone, and more distal pin location decreased pin pullout strength. We did not observe a significant mechanical advantage of predrilling for modern external fixator pins. The near cortex of a pin inserted into 2 cortices without predrilling did not exhibit substantial stripping effect.
Output: no
