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.

Input: Consider Input: Question: One of the following types of transport through membranes does NOT exist: 
 Options:  <0> Ion transport facilitated by ionophore (against electrochemical gradient). <1> Facilitated diffusion (in favor of electrochemical gradient) <2> Primary active transport (against electrochemical gradient). <3> Ionic channel (in favor of electrochemical gradient). <4> Simple diffusion (in favor of concentration gradient).

Output: pharmacology


Input: Consider Input: Question: The reaction conditions for the preparation of 2-methyl-2-methoxypropan-1-ol from 2,2-dimethyloxirane are: 
 Options:  <0> Methanol in acid medium. <1> Lithium aluminum hydride in methanol. <2> Methylmagnesium bromide and subsequent hydrolysis. <3> Sodium methoxide in methanol. <4> Triphenylphosphine in methanol.

Output: chemistry


Input: Consider Input: Question: An increase in blood pressure between 80 and 150 mmHg increases diuresis because: 
 Options:  <0> The glomerular filtration increases exponentially. <1> Decreases the peritubular reabsorption of water. <2> The efferent arteriole contracts. <3> Proportionally increases renal blood flow. <4> The afferent arteriole contracts.


Output: biology
