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 human umbilical cord-derived mesenchymal stem cells protect against experimental colitis via CD5 ( + ) B regulatory cells?
Answer: HUC-MSCs protected against experimental colitis by boosting the numbers of CD5(+) B cells and IL-10-producing CD5(+) Bregs, and correcting Treg/Th17/Th1 imbalances.

Ex Output:
yes


Ex Input:
Question: Do divergent growth strategies between red algae and kelps influence biomechanical properties?
Answer: We propose that divergent patterns in the distribution of material properties along blades may have different consequences for the performance of kelps and red algae. The positioning of younger tissues at the blade base for kelps may enable these species to attain larger body sizes in wave-swept habitats.

Ex Output:
yes


Ex Input:
Question: Does glucose uptake increase relative to oxygen consumption during short-term hibernation?
Answer: In this model of short-term hibernation, glucose and lactate uptake increase relative to oxygen consumption during sustained ischemia, and temporally coincide with the recovery of bioenergetics. The findings are consistent with the notion that glycolytically derived ATP is important for the maintainance of energy supply during sustained ischemia.

Ex Output:

yes
