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: The determined (or systematic) errors that can be committed in an analytical method: 
 Options:  <0> They cause the data to spread more or less symmetrically with respect to a mean value. <1> They have a definite value and an assignable cause, giving rise to a bias in the results of a series of measures. <2> They come reflected in the precision of a measurement. <3> They are never attributable to instrumental measuring devices. <4> They result in outliers, which differ greatly from the others in a set of duplicate measures data.
Example Output: pharmacology

Example Input: Question: Histone deacetylases (HDAC) promote: 
 Options:  <0> A less condensed chromatin. <1> A weaker link between histones and DNA in nucleosomes. <2> The acetylation of lysine residues in histones. <3> That the poly (A) tail of the histone messenger RNAs be more extensive. <4> The termination of the transcription and the genetic silencing.
Example Output: pharmacology

Example Input: Question: The square of Pearson's correlation coefficient is: 
 Options:  <0> The coefficient of variation. <1> The coefficient of determination. <2> The slope of the regression line. <3> The regression coefficient. <4> The covariance.
Example Output:
pharmacology
