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:

Ex Input:
Question: Does dll1 haploinsufficiency in adult mice lead to a complex phenotype affecting metabolic and immunological processes?
Answer: In conclusion, slight alterations in one player of Notch signaling alter the entire organism, emphasizing the fine-tuning character of this pathway in a high number of processes.

Ex Output:
yes

Ex Input:
Question: Does neutralization of vascular endothelial growth factor slow progression of retinal nonperfusion in patients with diabetic macular edema?
Answer: Just as high VEGF levels contribute to progression of retinal nonperfusion in retinal vein occlusion, the same is true in patients with DME, suggesting that regardless of the underlying disease process, high levels of VEGF can cause closure of retinal vessels. However, our data also suggest that VEGF-induced worsening of retinal perfusion in DME is superimposed on another cause of more gradually worsening perfusion, possibly glucotoxicity. Thus, monthly injections of ranibizumab can slow, but not completely prevent, retinal capillary closure in patients with DME.

Ex Output:
yes
