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 Input: Question: By reaction of carbonyls with primary and secondary amine, the following are obtained: 
 Options:  <0> Iminas and oximes. <1> Iminas and enaminas. <2> Oxazones and hydrazones. <3> Semicarbazones and nitrones. <4> None of the above.
Example Output: chemistry

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 drug with a seemingly monocompartmental distribution pattern is administered in the form of i.v. perfusion. at a constant speed of 20 mg / h for 48 h. Once the perfusion is finished, three blood samples are taken, which, when analyzed, allow the calculation of the primary parameters of the model Kel = 0.0495 h-1, concentration at the end of the perfusion (C48h) = 5,553 μg / mL, Vd = 66 L. At what time would the steady state be reached ?: 
 Options:  <0> 14 h. <1> 28 h. <2> 42 h. <3> 56 h. <4> 70 h.
Example Output:
