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: Why is chlorophyll green ?: 
 Options:  <0> Absorbs all wavelengths of the visible spectrum. <1> Absorbs wavelengths only from the red and ultra-red parts of the spectrum (680nm, 700nm). <2> Absorbs wavelengths in the red and blue parts of the visible spectrum. <3> Absorbs wavelengths only from the blue part of the visible spectrum. <4> Absorbs in the near ultraviolet.

Ex Output:

Ex Input:
Question: A parameter of great importance in chromatography is the equivalent height of theoretical plate (H). The van Deemter equation describes the behavior of a filler column for gas-liquid chromatography, where H = A + (B / u) + Cu, so that: 
 Options:  <0> C is the parameter that is taken as a measure of the quality of the filling of the column. <1> A is the coefficient that collects the contribution of longitudinal diffusion. <2> B is the parameter that is related to the resistance to the transfer of matter that opposes the stationary phase. <3> u is the linear velocity of the mobile phase. <4> B is canceled in columns without filling.

Ex Output:
