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.

Ex Input:
Question: Is stemness Derived from Thyroid Cancer Cells?
Answer: Our findings support our earlier hypothesis that stemness in thyroid cancer is derived via EMT rather than from resident thyroid stem cells. In mice with a thyroid-specific knock-in of oncogenic Braf (LSL-Braf((V600E))/TPO-Cre), the neoplastic changes were dependent on thyroid cell differentiation and the onset of stemness must have been derived from differentiated thyroid epithelial cells. Furthermore, celastrol suppressed TGF-1 induced EMT in thyroid cancer cells and may have therapeutic potential.

Ex Output:
yes

Ex Input:
Question: Does incidental parathyroidectomy during thyroid surgery cause transient symptomatic hypocalcemia?
Answer: Unintended parathyroidectomy, although not uncommon, is not associated with symptomatic postoperative hypocalcemia. Modified radical neck dissection may increase the risk of incidental parathyroidectomy. Most of the glands removed were intrathyroidal, so changes in surgical technique are unlikely to markedly reduce this risk.

Ex Output:
no

Ex Input:
Question: Is loss to follow-up of cervical smears without endocervical columnar cells disturbing?
Answer: Repeating ECC- smears has a low follow-up rate but also lacks evidence-based necessity. However, for the other 6-month recommended Pap smears, one in five women had still not responded within one year, so improvement is necessary.

Ex Output:
no
