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: Are c3 and C4 strongly related to adipose tissue variables and cardiovascular risk factors?
Answer: A strong relation between C3, C4 and C3a-desArg levels, adipose tissue and risk factors of CVD was established. The data support that the adipose tissue produces complement components and generates initiators of inflammation, such as C3a and C5a, able to trigger a cyto/chemokine response, in proportion to the amount of adipose tissue. This corroborates the concept that complement contributes to the low-grade inflammation associated with obesity.
Example Output: yes

Example Input: Question: Does histologic evaluation of in vivo femtosecond laser-generated capsulotomies reveal a potential cause for radial capsular tears?
Answer: Femtosecond laser can perform a capsulotomy with high reliability. In comparison to a highly experienced cataract surgeon, the achieved results in size are similar. In terms of circularity, the femtosecond laser was superior the manual procedure. Better refractive outcomes based on a 360°-degree optic overlap seem to be possible, especially for less experienced surgeons.
Example Output: yes

Example Input: Question: Do self-report symptoms differ between younger and older dizzy patients?
Answer: The clinician should be aware of differences in self-report dizziness symptoms in older patients. Older patients who do not have vertigo may be told that their symptoms are normal for their age, when, in fact, they may have an undiagnosed vestibular system impairment.
Example Output:
yes
