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: Does metoclopramide influence the frequency of propofol-induced spontaneous movements?
Answer: Metoclopramide does not affect the frequency of propofol-induced movements, but propofol and fentanyl doses influence the frequency of movements during propofol induction.
Example Output: no

Example Input: Question: Does overexpression of long noncoding RNA HOTAIR predict a poor prognosis in patients with cervical cancer?
Answer: our data indicate that high expression of HOTAIR is involved in cervical cancer progression and could be a potential target for diagnosis and gene therapy.
Example Output: yes

Example Input: Question: Does minimal extrathyroid extension affect the relapse-free survival of patients with papillary thyroid carcinoma measuring 4 cm or less over the age of 45 years?
Answer: These findings suggest that tumors with minimal extension should be classified to have the same T grade as those without such extension, and upstaging of such tumors is therefore not appropriate.
Example Output:
no
