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: Does developmental changes in spatial distribution of in vivo fluorescence and epidermal UV absorbance over Quercus petraea leave?
Answer: The spatial pattern of epidermal UV-screen over the area of oak leaves is related to leaf anatomy during development. In vivo spectroscopy and fluorescence imaging of the leaf surface showed the distribution of pigments within the leaf and hence can provide a tool to monitor optically the leaf development in nature.
[EX A]: yes

[EX Q]: Question: Are all cues created equal : the case for facilitating the acquisition of typical weighting strategies in children with hearing loss?
Answer: Spectral degradation affects children more than adults, but that degradation cannot explain the greater diminishment in children's weighting of FRT. It is suggested that auditory training could strengthen the weighting of spectral cues for implant recipients.
[EX A]: no

[EX Q]: Question: Does critical appraisal of : The endotracheal tube air leak test predict extubation outcome in critically ill pediatric patients . Pediatr Crit Care Med 2008 ; 9:490-496?
Answer: Pediatric patients who are otherwise candidates for extubation but do not have an endotracheal airleak may successfully be extubated.
[EX A]:
