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.

Question: Does expression of the pair-rule gene homologs runt , Pax3/7 , even-skipped-1 and even-skipped-2 during larval and juvenile development of the polychaete annelid Capitella teleta support a role in segmentation?
Answer: C. teleta eve, Pax3/7 and runt homologs all have distinct expression patterns and share expression domains with homologs from other bilaterians. None of the pair-rule orthologs examined in C. teleta exhibit segmental or pair-rule stripes of expression in the ectoderm or mesoderm, consistent with an independent origin of segmentation between annelids and arthropods.
no

Question: Does acute ethanol always affect delay discounting in rats selected to prefer or avoid ethanol?
Answer: Our data indicate that in these lines of animals, alcohol preference or avoidance has no impact on delay discounting following acute ethanol exposure. It is possible that other genetic models or lines may be differentially affected by alcohol and exhibit qualitatively and quantitatively different responses in delay discounting tasks.
no

Question: Does low-dose sufentanil potentiate intrathecal morphine for perioperative analgesia after major colorectal surgery?
Answer: These results do not support the addition of 10 microg ITS to 0.4 mg ITM for colorectal surgery, as low dose sufentanil does not improve intraoperative and postoperative analgesia in this setting.
no
