TASK DEFINITION: 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.
PROBLEM: Question: Does resident participation affect surgical outcomes , despite introduction of new techniques?
Answer: In the context of this single surgical operation, resident participation does not substantially affect major complication rates. The common residency training paradigm provides clinical experience and supervision without necessarily impacting patient safety. Analysis of additional operations in different settings will be necessary.

SOLUTION: no

PROBLEM: Question: Does metoclopramide influence the frequency of propofol-induced spontaneous movements?
Answer: Metoclopramide does not affect the frequency of propofol-induced movements, but propofol and fentanyl doses influence the frequency of movements during propofol induction.

SOLUTION: no

PROBLEM: Question: Does a novel two-step genome editing strategy with CRISPR-Cas9 provide new insights into telomerase action and TERT gene expression?
Answer: We develop a two-step CRISPR-Cas9 genome editing strategy to introduce precise modifications at the endogenous TERT locus in human cell lines. This method provides a useful tool for studying telomerase biology, and suggests a general approach to edit loci with low targeting efficiency and to purify and visualize low abundance proteins.

SOLUTION:
yes
