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 haploinsufficiency the key mechanism of pathogenesis in a heterozygous Elovl4 knockout mouse model of STGD3 disease?
Answer: The detailed characterization of this animal model provides the first in vivo evidence that Elovl4 haploinsufficiency is not the underlying key disease mechanism in STGD3. The results are consistent with a dominant negative mechanism for the deletion mutation. The Elovl4 knockout mouse is one of three complementary animal models that will help elucidate the disease mechanism.
[EX A]: no

[EX Q]: Question: Does short-term enteral glutamine enhance protein accretion in burned children : a stable isotope study?
Answer: Rapid protein accretion does not occur with short-term enteral glutamine supplementation. Several days of glutamine supplementation may be required to restore plasma glutamine levels and stimulate protein synthesis.
[EX A]: no

[EX Q]: Question: Do smokers exhibit biased neural processing of smoking and affective images?
Answer: Results suggest that cognitive biases may extend across classes of stimuli among smokers. This raises important questions about the fundamental meaning of cognitive biases, and suggests the need to consider generalized cognitive biases in theories of drug use behavior and interventions based on cognitive bias modification.
