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 Q]: Question: Is laser in situ keratomileusis surgery safe for military personnel?
Answer: There is a high risk of potential traumatic flap problems after LASIK and it is not recommended in army service.
[EX A]: no

[EX Q]: Question: Does greater body mass independently predict less radiographic progression on X-ray and MRI over 1-2 years?
Answer: Greater BMI is associated with a lower risk of progression on X-ray and MRI over 2 years. Subjects with greater BMI also demonstrate less bone oedema at baseline. Greater BMI may indicate a less aggressive RA phenotype and aid in risk stratification.
[EX A]: yes

[EX Q]: Question: Does cilostazol protect endothelial cells against lipopolysaccharide-induced apoptosis through ERK1/2- and P38 MAPK-dependent pathways?
Answer: Cilostazol protects HUVECs against LPS-induced apoptosis by suppressing mitochondria-dependent apoptotic signaling. Activation of ERK1/2 and p38 MAPKs, and subsequent stimulation of CREB phosphorylation and Bcl-2 expression, may be responsible for the cellular signaling mechanism of cilostazol-mediated protection.
[EX A]:
yes
