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: Do expanded effector memory T-lymphocytes in DBA/2 mice inhibit the growth of SL2 tumours?
Answer: SL2 tumours induce expansion of effector memory lymphocytes in DBA/2 mice. However, expanded effector memory lymphocytes do not inhibit the growth of tumours.

Output: no


Input: Consider Input: Question: Does treatment of subclinical hypothyroidism affect bone mass as determined by dual-energy X-ray absorptiometry , peripheral quantitative computed tomography and quantitative bone ultrasound in Spanish women?
Answer: Our results indicate that adequate metabolic control through replacement treatment with L-T4 in pre- and postmenopausal women does not affect bone mass.

Output: no


Input: Consider Input: Question: Is skin pentosidine in very early hip/knee osteoarthritis ( CHECK ) a strong independent predictor of radiographic progression over 5 years follow-up?
Answer: Pentosidine adds to prediction of radiographic progression and burden of osteophyte formation and uCTXII to radiographic progression and burden of JSN, but overall skin pentosidine did not perform better that uCTXII in predicting radiographic progression or burden. Burden of damage over 5 years is mainly determined by radiographic joint damage at baseline.


Output: no
