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 microelectrode is characterized by: 
 Options:  <0> Give answers in steady state. <1> Always need an inert electrolyte. <2> Always need a potentiostatic system. <3> Do not need a reference electrode. <4> Always need agitation.
Example Output: chemistry

Example Input: Question: The presence (x = 1) or absence (x = 0) of bacteriuria has been determined in a group of subjects. What kind of variable is it? 
 Options:  <0> Ordinal. <1> Numeric <2> Categorical <3> Continuous quantitative <4> Discrete quantitative.
Example Output: medicine

Example Input: Question: 30-year-old man without a history of interest. He came to the clinic because of the presence of small erythematous-violaceous lesions that appear elevated on palpation, in the pretibial region. The analytical study shows a blood count and coagulation study without alterations and in the biochemistry, creatinine and ions are also within the range of normality. The study of urinary sediment demonstrates hematuria, for which the patient had already been studied on other occasions, without obtaining a definitive diagnosis. Regarding the entity that you suspect in this case is FALSE that: 
 Options:  <0> In 20% to 50% of cases there is an elevation of the serum IgA concentration. <1> In the renal biopsy the mesangial deposits of IgA are characteristic. <2> The existence of proteinuria in the nephrotic range is frequent. <3> It is considered a benign entity since less than 1/3 of the patients progress to renal failure. <4> Skin biopsy allows the diagnosis to be established in up to half of the cases.
Example Output:
