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: In what type of hearing loss is the phenomenon of recruitment or recruitment characteristic? 
 Options:  <0> Transmission hearing loss. <1> Mixed hearing loss. <2> Central hearing loss. <3> Retrocochlear hearing loss. <4> Cochlear hearing loss.
Example Output: medicine

Example Input: Question: Mitochondrial oxidative phosphorylation is regulated by: 
 Options:  <0> Mitochondrial steroid hormones. <1> Apoptosis <2> Thermogenin <3> The cytochrome c. <4> The cellular energy charge.
Example Output: chemistry

Example Input: Question: Plasma ICP is more suitable for rapid multielemental analysis than flame atomic absorption methods because: 
 Options:  <0> The linearity interval is not wide, which allows for very sensitive analyzes. <1> The ICP has several possibilities to introduce the sample using different types of nebulizers. <2> They use two photomultiplier tubes, one for the ultraviolet region and the other for the visible one. <3> It has load-coupled silicon solid-state detectors that allow simultaneous monitoring of a large number of lines, reducing analysis time, sample volume and improving detection limits. <4> It is not correct, because with the ICP plasma, multielemental analysis can not be done.
Example Output:
chemistry
