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: The completion of the translation: 
 Options:  <0> It takes place in AUG codons. <1> It is produced by incorporation of an empty tRNA. <2> It occurs when the ribosome reaches the end of the mRNA. <3> It does not consume energy. <4> It is mediated by proteins with structure similar to tRNA.
Example Output: biology

Example Input: Question: Beta-adrenergic receptor blocking drugs: 
 Options:  <0> They cause hypotension in individuals with normal blood pressure. <1> They increase the atrio-ventricular conduction velocity. <2> They cause negative inotropism. <3> They provoke a positive chronotropic effect. <4> They increase the secretion of renin.
Example Output: pharmacology

Example Input: Question: In a meta-analysis of 15 studies, the incidence of myocardial infarction with the new drug Tromboclean is 10.8% compared to 8% with heparin. The relative risk is 1.35, with a 95% confidence interval of 1.15 to 1.50 and absence of significant heterogeneity between studies (p-value of heterogeneity = 0.95). Point out the CORRECT answer: 
 Options:  <0> The heterogeneity is not significant, which suggests that the results are inconclusive. <1> Trombo Clean presents a risk of myocardial infarction similar to that of heparin. <2> It can not be ruled out with a 95% confidence that Tromboclean reduces the risk of myocardial infarction by 50%. <3> Thromboclean increases the absolute risk of myocardial infarction between 15% and 50%. <4> Heparin presents a significantly lower risk of myocardial infarction than Tromboclean.
