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: Juan is 60 years old, smokes 2 packs / day for years and has been talking about persistent cough for 6 months. Check that your left eyelid is more droopy and that the pupil of that eye is smaller. Juan says that the medial part of his left hand is numb and less powerful. Your doctor checks for palpebral ptosis and left miosis; check that you can close both eyelids with symmetry and that both pupils respond correctly to the light. He also checks that he does not sweat through the left side of the face, that he feels less the puncture on the inside surface of that hand and that he has less strength in the grip of that hand. Regarding the ocular symptomatology, where is the lesion located? 
 Options:  <0> The sympathetic fibers, at some level that would span from the hypothalamus to the Clark-intermediate column of the dorsal medulla. <1> The left common ocular motor nerve in the mesencephalon. <2> The nucleus of Edinger-Westphal, above the nucleus of the left ocular motor nerve. <3> The parasympathetic fibers, at some level that would extend from the EdingerWestphal nucleus to the constrictor muscle of the left pupil. <4> The tarsal muscle exclusively.
Example Output: medicine

Example Input: Question: A parameter of great importance in chromatography is the equivalent height of theoretical plate (H). The van Deemter equation describes the behavior of a filler column for gas-liquid chromatography, where H = A + (B / u) + Cu, so that: 
 Options:  <0> C is the parameter that is taken as a measure of the quality of the filling of the column. <1> A is the coefficient that collects the contribution of longitudinal diffusion. <2> B is the parameter that is related to the resistance to the transfer of matter that opposes the stationary phase. <3> u is the linear velocity of the mobile phase. <4> B is canceled in columns without filling.
Example Output: chemistry

Example Input: Question: Regal water dissolves gold because of its two components: 
 Options:  <0> Sulfuric acid acts as an oxidant and hydrochloric acid forms a soluble chlorinated complex of Au3 +. <1> Hydrochloric acid increases the oxidizing power of nitric acid. <2> Nitric acid acts as an oxidant and hydrochloric acid forms a soluble chlorine complex of Au3 +. <3> Hydrochloric acid acts as an oxidant and nitric acid forms a soluble complex of Au3 +. <4> Nitric acid acts as an oxidant and hydrochloric acid forms a soluble chlorinated complex of Au2 +.
