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 Input:
Question: Does a cytotoxic phenotype predict clinical outcome in anaplastic large cell lymphomas?
Answer: In primary biopsies of patients with ALCL, the presence of a cytotoxic phenotype is not related to clinical outcome of the disease.

Ex Output:
no

Ex Input:
Question: Are intrafollicular interleukin-8 , interleukin-12 , and adrenomedullin the promising prognostic markers of oocyte and embryo quality in women with endometriosis?
Answer: The levels of IL-8, IL-12, and adrenomedullin may be good indicators of embryo and oocyte quality in endometriosis patients undergoing IVF. Further studies are necessary to ascertain the potential of these markers for oocyte and embryo developmental competence which may help improve the chances of a successful IVF in endometriosis patients.

Ex Output:
yes

Ex Input:
Question: Are conventional pattern-reversal VEPs equivalent to summed multifocal VEPs?
Answer: Full-field cVEPs cannot be simply related to the sum of mfVEPs when each are recorded under their typical conditions. The stimulation rate has the largest influence on the differences between the two response types. The findings suggest that contributions from extrastriate sources are greater with the cVEP paradigm or the slowed mfVEP sequence than with the standard mfVEP paradigm.

Ex Output:
no
