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 clinical presentation and disease course of inflammatory bowel disease differ by race in a large tertiary care hospital?
Answer: We identified significant differences in disease characteristics and extraintestinal manifestations between AA and Ca IBD patients in a large tertiary care population. These results have implications for future genotype-phenotype studies.

Output: yes

Input: Consider Input: Question: Does post-exercise heart-rate recovery correlate to resting heart-rate variability in healthy men?
Answer: HRR from the 1st to 5th min post-exercise negatively correlated with parasympathetic modulation in resting orthostatic, but showed no correlation in supine position. At the 3rd and 5th min, a positive correlation with combined sympathetic-parasympathetic modulation in both positions was observed.

Output: yes

Input: Consider Input: Question: Is eD bedside point-of-care lactate in patients with suspected sepsis associated with reduced time to iv fluids and mortality?
Answer: Implementation of bedside POC lactate measurement in adult ED patients with suspected sepsis reduces time to test results and time to administration of IV fluids but not antibiotics. A significant reduction in mortality and ICU admissions was also demonstrated, which is likely due, at least in part, to POC testing.
Output: yes
