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: Liquid chromatography using linked stationary phases can be divided into normal phase and reverse phase phases. In this context it can be said that:
Options: <0> The main separation mechanism in reverse phase is the distribution, while adsorption also plays a very important role in the normal phase. <1> In normal phase chromatography, a large number of non-polar stationary phases can be used. <2> The main separation mechanism in normal phase is the distribution, while the adsorption plays a very important role in the reverse phase. <3> In reverse phase chromatography, the stationary phase is polar and the non-polar eluents. <4> In reverse phase chromatography, a large number of polar stationary phases can be used.

Ex Output:
