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: Transpeptidation is the step in the biosynthesis of peptidoglycan in which:
Options: <0> The union of N-acetylmuramic acid with N-acetyl glucosamine occurs inside the bacterial cell. <1> The exit of the precursors from the cytoplasm to the outside takes place. <2> The binding of the precursor to the peptidoglycan occurs outside, by glycosidic bonds. <3> The binding, by means of interpeptide bridges, between peptidoglycan chains. <4> The autolisinas act forming pores in its structure.
Example Output: pharmacology

Example Input: Question: The chloride present in a solution can be determined volumetrically, by the Mohr method, using Ag (I) as a reagent. What indicator is used in this assessment ?:
Options: <0> K2Cr2O7. <1> Fe2 (SO4) 3. <2> K2CrO4. <3> KSCN <4> FeSO4.
Example Output: chemistry

Example Input: Question: The cyclotron ion resonance by Fourier transform is the basis of:
Options: <0> A mass ionization system useful for elementary analysis. <1> A system of atomization that is applied in atomic absorption for elements capable of generating hydrides. <2> A mass analyzer. <3> A system for introducing the sample in plasma emission spectrometry. <4> A detector system in mass spectrometry.
