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 in vivo imaging of antileukemic drug asparaginase reveal a rapid macrophage mediated clearance from the bone marrow?
Answer: We show that asparaginase is rapidly cleared from the serum by liver, spleen and bone marrow-resident phagocytic cells. As a consequence of this efficient uptake and protease mediated degradation, particularly bone marrow resident macrophages may provide a protective niche to leukemic cells.

Output: yes

Input: Consider Input: Question: Is high salt intake associated with a higher risk of cardiovascular events : a 7.2-year evaluation of a cohort of hypertensive patients?
Answer: In a cohort of hypertensive patients, high salt intake independently predicts the occurrence of CV events, particularly of stroke.

Output: yes

Input: Consider Input: Question: Is tumor invasion depth a useful pathologic assessment for predicting outcomes in cervical squamous cell carcinoma after neoadjuvant radiotherapy?
Answer: The TID or TIDC measured at the cervical internal surface is a useful and easily applied pathologic prognostic factor for distant metastasis and survival outcomes in patients with cervical squamous cell carcinoma treated with neoadjuvant RT or CCRT.
Output: yes
