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 apoptosis inhibitor-5 overexpression associated with tumor progression and poor prognosis in patients with cervical cancer?
Answer: API5 expression is associated with pERK1/2 in a subset of cervical cancer patients and its expression predicts poor overall survival, supporting that API5 may be a promising novel target for therapeutic interventions.

Ex Output:
yes

Ex Input:
Question: Does long-term treadmill exercise attenuate tau pathology in P301S tau transgenic mice?
Answer: Our results suggest that forced treadmill exercise differently affects the brain and spinal cord of aged P301S tau mice, with greater benefits observed in the spinal cord versus the brain. Our work adds to the growing body of evidence that exercise is beneficial in tauopathy, however these benefits may be more limited at later stages of disease.

Ex Output:
yes

Ex Input:
Question: Does an environmental route of exposure affect the formation of nanoparticle coronas in blood plasma?
Answer: This work shows how a self-assembling protein, class II hydrophobin HFBII, with interesting biocompatible coating properties, strongly adsorbs on polystyrene NPs. HFBII is also shown to reduce aggregation of the NPs in human plasma which can increase their bioavailability with potential use in biomedical applications. The results here are also of significance for understanding possible interactions of NPs with living organisms. Hydrophobins are secreted in large quantities into the environment by fungi and this work shows how the biological environment of NPs determines the surface and colloidal properties of the particles by forming a protein corona, and that the history of the particle environment, here simulated with hydrophobin exposure, affects both plasma protein corona formation and dispersion behavior. This work thus simulates how alternative exposure routes affect nanoparticle properties, important in understanding the biological fate of NPs.

Ex Output:
yes
