Given the task definition, example input & output, solve the new input case.
In this task, you are given a question and answer options for that question. Using this information, you have to classify each text into different topics: medicine, nursery, psychology, chemistry, pharmacology, biology.
Example: Question: A distension is defined as:
Options: <0> Soft tissue injury. <1> Forced movement of abrupt production. <2> Injury by stretching a muscle. <3> Injury of the joint capsule. <4> Interruption in the continuity of a bone.
Output: nursery
Distension means Bloating and swelling in the belly area. It does not have much to do with chemistry, psychology, pharmacology, biology and medicine. Hence, the correct topic is nursery.

New input case for you: Question: Within the congenital anomalies of the abdominal wall are the omphalocele and gastroschisis. Both entities are defects of the wall. What is the difference between them?
Options: <0> Omphalocele occurs at the umbilical level and gastroschisis at the epigastric level. <1> The defect, in the case of gastroschisis, is larger than the omphalocele. <2> In the omphalocele, a peritoneal sac covers the abdominal contents and not gastroschisis. <3> Omphalocele, unlike gastroschisis, is frequently associated with intestinal atresia. <4> Unlike the omphalocele, in gastroschisis the surgical treatment can be deferred.
Output:
medicine
