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 an absent pulse sensitive for the early detection of peripheral arterial disease?
Answer: Pulse palpation is not sensitive for the detection of PAD compared to ABI. More than two thirds of the patients within our cohort with PAD of either the left or right leg had a detectable pulse.

Ex Output:
no


Ex Input:
Question: Does star-shaped tetraspermine enhance cellular uptake and cytotoxicity of T-oligo in prostate cancer cells?
Answer: SSTS significantly enhanced therapeutic benefits associated with the use of T-oligo and can be developed as a delivery vehicle for its in-vivo therapeutic applications.

Ex Output:
yes


Ex Input:
Question: Does thrombomodulin influence the Survival of Patients with Non-Metastatic Colorectal Cancer through Epithelial-To-Mesenchymal Transition ( EMT )?
Answer: Our study demonstrates that patients with non-metastatic CRC display low TM expression in their tumors and exhibit reduced DFS and OS. The enhanced expression of mesenchymal markers and COX-2 may be involved in the mechanisms that underlie recurrence in patients with cancer displaying low TM expression.

Ex Output:

yes
