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 histamine released in acute thermal injury in human skin in vivo : a microdialysis study?
Answer: Histamine is not released in human skin during the acute phase of a thermal injury.
Example Output: no

Example Input: Question: Is tobacco smoking associated with decreased semen quality?
Answer: Results demonstrated a decline in semen quality in a dose dependent tobacco smoking manner.
Example Output: yes

Example Input: Question: Does 2D cine DENSE with low encoding frequencies accurately quantify cardiac mechanics with improved image characteristics?
Answer: For 2D cine DENSE with through-plane dephasing, the encoding frequency can be lowered to 0.04cycles/mm without compromising the quantification of twist or strain. The amount of wrapping can be reduced with this lower value to greatly simplify the input to unwrapping algorithms. The strain and twist results from studies using different encoding frequencies can be directly compared.
Example Output:
yes
