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: Do workers of a drywood termite work?
Answer: Thus, in contrast to general perception where termite workers are considered equivalent to workers in Hymenoptera, the 'large immatures' of C. secundus did not behave as workers that help in raising younger siblings. This apparently is not necessary as the colony lives inside its food. These results, which are likely to be typical for wood-dwelling termites, open the possibility that large complex group living can evolve without altruistic helping and that costly altruistic helping by workers in termites evolved only as a second step.
[EX A]: no

[EX Q]: Question: Does overexpression of long noncoding RNA HOTAIR predict a poor prognosis in patients with cervical cancer?
Answer: our data indicate that high expression of HOTAIR is involved in cervical cancer progression and could be a potential target for diagnosis and gene therapy.
[EX A]: yes

[EX Q]: Question: Does microRNA-29b regulate migration in oral squamous cell carcinoma and its clinical significance?
Answer: MiR-29b acts as an oncomir, promoting cell migration through CX3CL1 suppression, and could be a potential therapeutic target for preventing OSCC progression.
[EX A]:
yes
