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 mYC a metastasis gene for non-small-cell lung cancer?
Answer: Potential markers for detection of metastasis were identified and validated for diagnosis of human biopsies. These markers may represent targets for future therapeutic intervention as they include genes such as Gata4 that are exclusively expressed during lung development.

Ex Output:
yes


Ex Input:
Question: Does phosphoinositide 3-kinase-δ regulate fungus-induced allergic lung inflammation through endoplasmic reticulum stress?
Answer: These findings suggest that PI3K-δ regulates Af-induced steroid-resistant eosinophilic allergic lung inflammation through ER stress.

Ex Output:
yes


Ex Input:
Question: Is retinol-binding protein-4 strongly associated with insulin sensitivity in normal pregnancies?
Answer: The increased fat mass and insulin resistance during normal pregnancy was best explained by measures of fat mass. However, the increase in RBP4 from early to late pregnancy, associated with a decline in insulin sensitivity, potentially indicates interactions with glucose metabolism.

Ex Output:

no
