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 examination assist in the detection of systemic relapse of testicular germ cell tumour?
Answer: We suggest that, for patients following a planned programme of appointments and investigations, physical examination rarely contributes to the detection of systemic relapse in the follow-up of testicular germ cell tumours. It may therefore be possible to reconfigure follow-up to focus on investigations and telephone contact. We estimate that this change might be appropriate for 40% of attendances and might be welcomed by patients, many of whom find follow-up burdensome. If such a change were considered, patient education would be essential to ensure continuing compliance with the follow-up protocol.

Output: no


Input: Consider Input: Question: Does a cytotoxic phenotype predict clinical outcome in anaplastic large cell lymphomas?
Answer: In primary biopsies of patients with ALCL, the presence of a cytotoxic phenotype is not related to clinical outcome of the disease.

Output: no


Input: Consider Input: Question: Is a major imprinted gene involved in hydatidiform mole located in 2q31.2-qter or 5q34-qter?
Answer: If the molar phenotype is caused by paternal excess of one gene, only, it is unlikely that this gene is located telomeric to genome position 179Mb on chromosome 2. And similarly, if the phenotype complete mole is caused by the presence of exclusively paternally imprinted alleles of one gene, this gene is not located telomeric to genome position 165Mb on chromosome 5.


Output: no
