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: Do manual Lymphatic Drainage and Active Exercise Effects on Lymphatic Function Translate Into Morbidities in Women Who Underwent Breast Cancer Surgery?
Answer: MLD and active exercise effects are equivalent with regard to morbidity. Minor changes in lymphatic function associated with either MLD or active exercises were not related to patients' symptoms or signs.

Ex Output:
no


Ex Input:
Question: Does early primary repair of tetralogy of Fallot lead to increased postoperative resource utilization?
Answer: Extracardiac anomalies, prematurity, low birth weight, and nonelective surgical intervention are predictors of increased morbidity and increased hospital resource utilization and impose a significant cost burden to the care of these patients. Early primary repair of tetralogy of Fallot can be safely performed without any increase in morbidity or increased hospital resource utilization.

Ex Output:
no


Ex Input:
Question: Do variations in LOXL1 associated with exfoliation glaucoma affect amine oxidase activity?
Answer: The R141L and G153D variations in the NH(2)-terminal region of LOXL1 do not affect the amine oxidase activity of LOXL1. This is consistent with recent genetic findings on the reversal of risk alleles of R141L and G153D in different ethnic backgrounds. Our results suggest that other unknown genetic factors or molecular mechanisms may be more relevant to the development of XFG.

no
