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.

Ex Input:
Question: Which of the following situations would noticeably decrease the transcription of a gene? 
 Options:  <0> The presence of a repressor and an inducing molecule. <1> The binding of RNA polymerase to DNA. <2> The presence of a repressor and a correpressor molecule. <3> The presence of an activator and its signal molecule. <4> The presence of a mutated repressor that could not bind to DNA.

Ex Output:
pharmacology


Ex Input:
Question: The gas used to generate the ICP plasma (coupled induction plasma) is: 
 Options:  <0> Hydrogen for being diatomic, chemically inert and with a low ionization energy. <1> Oxygen because it is diatomic, highly reactive and with a high ionization energy. <2> Argon, being monatomic, chemically inert and with a high ionization energy. <3> Xenon, being monatomic, highly reactive and with a low ionization energy. <4> None of the above is correct, because the gas used is helium.

Ex Output:
chemistry


Ex Input:
