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: In HPLC and under ideal conditions, the chromatographic peaks should have the shape of Gaussian peaks with perfect symmetry, although in reality, the peaks are not perfectly symmetrical and can present fronts and tails. The asymmetry factor: 
 Options:  <0> It is used to measure the relative retention of the two components of a sample so that in perfectly symmetrical compounds it is 0. <1> It is used to measure the degree of symmetry of a peak and is defined at the peak width corresponding to 10% of the peak height. <2> It is a parameter that is calculated by measuring the width at the half-height of the chromatographic peak. <3> It relates to each other two successive chromatographic peaks, so that an asymmetry factor 1 indicates a total resolution of them. <4> It is a parameter related to the symmetry of the peaks, defined at a height equal to 10% of the width thereof.

Output: chemistry

Output: chemistry


Input: Consider 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.
