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.

Ex Input:
Question: Indicate the net charge of an amino acid with a neutral R group for a pH value below its pI: 
 Options:  <0> Negative net charge. <1> Positive net charge. <2> Without charge. <3> It is necessary to know the exact pH value to answer this question. <4> It is necessary to know the concentration of the amino acid to answer this question.

Ex Output:
chemistry


Ex Input:
Question: One of the following types of transport through membranes does NOT exist: 
 Options:  <0> Ion transport facilitated by ionophore (against electrochemical gradient). <1> Facilitated diffusion (in favor of electrochemical gradient) <2> Primary active transport (against electrochemical gradient). <3> Ionic channel (in favor of electrochemical gradient). <4> Simple diffusion (in favor of concentration gradient).

Ex Output:
pharmacology


Ex Input:
Question: In a patient with hepatic cirrhosis and ascites, which develops a pleural effusion with the following data in the pleural fluid: LDH 45 U / L (serum 220 U / L), protein ratio pleura / serum 0.3 and ratio LDH pleura / serum 0.2. What would be the right attitude? 
 Options:  <0> The study of the fluid with cell count, glucose, pH, ADA, cholesterol and culture should be expanded. <1> Blind pleural biopsy. <2> Diagnostic video-assisted thoracoscopy. <3> Empirical antibiotic therapy for suspected parapneumonic effusion. <4> Continue the treatment of your liver disease.
