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: Does cSTMP induce apoptosis and mitochondrial dysfunction in human myeloma RPMI8226 cells via CHOP-dependent endoplasmic reticulum stress?
Answer: Our results indicated that CSTMP could induce apoptosis and mitochondrial dysfunction in RPMI8226 cells via CHOP-dependent ER stress.

Ex Output:
yes

Ex Input:
Question: Is daily physical activity in patients with chronic obstructive pulmonary disease mainly associated with dynamic hyperinflation?
Answer: Daily physical activity of patients with COPD is mainly associated with dynamic hyperinflation, regardless of severity classification.

Ex Output:
yes

Ex Input:
Question: Does inhibition of urothelial P2X3 receptors prevent desensitization of purinergic detrusor contractions in the rat bladder?
Answer: In the rat bladder, medial and basal urothelial cells express P2X3R, and specific inhibition of the receptor leads to a more hyporeflexive bladder condition. This pathway may involve P2X3R driving a paracrine amplification of ATP released from umbrella cells to increase afferent transmission in the sub-urothelial sensory plexus and desensitization of P2X1-mediated purinergic detrusor contractions.

Ex Output:
yes
