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: Is orchidopexy without ligation of the processus vaginalis associated with an increased risk of inguinal hernia?
Answer: Our findings confirm that division without ligation of a patent processus vaginalis is usually followed by spontaneous peritoneal scarring and complete closure of the internal inguinal ring. Present technique is as effective as traditional orchidopexy and saves extra time spent for meticulous closure of the processus vaginalis or peritoneal tears.

Ex Output:
no


Ex Input:
Question: Is pKCε a negative regulator of PVAT-derived vessel formation?
Answer: PKCε negatively interferes with vessel progenitor differentiation via interaction with PAK-1.

Ex Output:
yes


Ex Input:
Question: Does breast tumor specific mutation in GATA3 affect physiological mechanisms regulating transcription factor turnover?
Answer: We propose that this specific, cancer-derived mutation in GATA3 deregulates physiologic protein turnover, stabilizes GATA3 binding across the genome and modulates the response of breast cancer cells to estrogen signaling.

Ex Output:

yes
