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.

Example Input: Question: Does asfotase Alfa Treatment improve Survival for Perinatal and Infantile Hypophosphatasia?
Answer: Asfotase alfa mineralizes the HPP skeleton, including the ribs, and improves respiratory function and survival in life-threatening perinatal and infantile HPP.
Example Output: yes

Example Input: Question: Are higher rates of viral suppression with nonnucleoside reverse transcriptase inhibitors compared to single protease inhibitors explained by better adherence?
Answer: A higher proportion of individuals using NNRTI-based regimens had viral suppression when compared to those taking single-PI-containing regimens, and this association was not confounded by higher levels of adherence. These results suggest that improved viral suppression on NNRTI regimens compared to single-PI regimens is more closely associated with regimen potency than higher levels of adherence.
Example Output: no

Example Input: Question: Do mRI biomarkers identify the differential response of glioblastoma multiforme to anti-angiogenic therapy?
Answer: MRI parameters following therapy vary based on class of AATx. Validation of clinically relevant MRI parameters for individual AATx agents is necessary before incorporation into routine practice.
Example Output:
yes
