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: A 70-year-old man presented with progressive dyspnea and a non-productive cough several years old. In chest X-ray, pleural plaques are seen in the mediastinal and diaphragmatic pleura. On CT, these plaques are confirmed, also appreciating the presence of reticulonodulillar involvement predominantly in lower fields. Among the following, what attitude would you recommend in the first place? 
 Options:  <0> Complete your smoking history. <1> Inquire about occupational exposure. <2> Request blood tests to rule out eosinophilia. <3> Do complete respiratory functional tests. <4> Propose a transbronchial biopsy.
Example Output: medicine

Example Input: Question: In suppression ion chromatography: 
 Options:  <0> A single column is used and the conductivity of the mobile phase is kept very low. <1> The eluent must be able to be removed selectively after separation and prior to the conductometric measurement. <2> The eluent incorporates a regenerating solution of strong acid flowing in the same direction as the mobile phase. <3> Weak exchangers are used from polystyrene polymers. <4> A mobile phase with ionic conductivity gradient is used.
Example Output: chemistry
