Example Input: Question: Indicate the correct answer regarding the pancreas: 
 Options:  <0> Your alpha cells secrete insulin. <1> Its F cells produce somatostatin, which accelerates the secretion of glucagon. <2> Your alpha cells secrete glucagon, which increases the concentration of blood glucose. <3> It is an exclusively endocrine gland. <4> Its delta cells secrete pancreatic polypeptide.
Example Output: nursery

Example Input: Question: Question linked to the image nº13 A 12-year-old boy who goes to primary care Pediatrics for fever, vomiting, abdominal pain and diarrhea. On cardiopulmonary auscultation, he presents with an ejection systolic murmur II / VI in a pulmonary focus with a fixed second unfolded noise, the remainder being the normal physical examination. For the evaluation of the murmur the pediatrician performs an ECG that is shown below. In relation to the interpretation of it, please indicate below the correct answer: 
 Options:  <0> It is a normal ECG. <1> He presents a first-degree atrioventricular block as the only alteration. <2> It presents a left extreme QRS axis. <3> It presents a QRS axis deviated to the right with an rsR' pattern. <4> There are clear signs of left ventricular hypertrophy.
Example Output: medicine

Example Input: Question: A coulometric evaluation: 
 Options:  <0> You do not need the current performance to be 100%. <1> It does not need an indicator system of the end point. <2> Always use a potentiostatic system. <3> It uses a titrant that is generated electrolytically. <4> You need a burette to add the titrant.
