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.

Input: Consider Input: Question: The fear or belief of suffering an important disease, which arises in the subject from the erroneous interpretation of their bodily symptoms, is the nuclear characteristic of:
Options: <0> The conversion disorder. <1> Hypochondria. <2> Panic disorder <3> The Depression <4> Somatization

Output: psychology

Input: Consider 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.

Output: chemistry

Input: Consider Input: Question: A randomized phase III clinical trial compared the efficacy of a new analgesic (experimental) with a control treatment (tramadol) in patients with chronic pain. The working hypothesis was that experimental treatment reduces pain more than tramadol. The effect of the two treatments was determined at 48 hours by reducing the score marked by the patient on an analog - visual scale from 0 to 100 mm. The mean reduction in the tramadol group was -27 and in the experimental group of -31. The hypothesis was contrasted for the differences, with the corresponding statistical test and a value of p = 0.03 was obtained. Regarding the previous study, which of the following conclusions seems more correct?
Options: <0> The study demonstrated clinically relevant differences. <1> The differences in the analgesic effect between the two treatments studied were significant. <2> The benefit - risk of the experimental treatment was better than that of tramadol. <3> The experimental treatment was 20% better than tramadol. <4> We can recommend the widespread use of experimental treatment, because it is more effective than tramadol in the treatment of chronic pain.
