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: Patients with liver cirrhosis may have ascites due to: 
 Options:  <0> Alteration of the coagulation factors. <1> Portal hypertension and serum hypoalbuminemia. <2> Decrease in hydrostatic pressure. <3> Irritation of the peritoneal membrane by bile salts. <4> Post-surgical and abdominal trauma.
Example Output: nursery

Example Input: Question: Patient with polyuria and polydipsia with a specific urine density greater than 1.040. From the following options indicate the most probable diagnosis: 
 Options:  <0> Alcohol intoxication <1> Suppression of ADH (vasopressin) by barbiturates. <2> Mellitus diabetes. <3> Lithium toxicity that causes diabetes insipidus. <4> Central deficit of ADH (vasopressin).
Example Output: pharmacology

Example Input: Question: The Arrhenius equation: 
 Options:  <0> It relates the speed of a chemical reaction with the so-called constant velocity and with the concentrations of the reactants raised to their stoichiometric coefficients. <1> It relates the constant of speed of a chemical reaction with the energy of activation of said reaction, so that if the energy, of activation is high the reaction is fast. <2> It is only fulfilled for unimolecular reactions. <3> It relates the speed constant to the temperature through the activation energy and the pre-exponential factor. <4> It allows to obtain the activation energy of an elementary reaction by only representing the decimal logarithm of the temperature versus the inverse of the reaction time.
Example Output:
