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: With respect to the distribution coefficient of a solute between two partially miscible liquids: 
 Options:  <0> Because it is a quotient between solute concentrations in the two phases, it is independent of temperature. <1> It does not depend on the total amount of solute in both parts. <2> It is useful to determine the molar mass of the solute. <3> If one phase is water and the other an organic solvent, it is usually used in medical and environmental chemistry to know the distribution of drugs and contaminants between these two types of media. <4> It only has physical significance when the liquid phases are in contact through a semipermeable membrane.
Example Output: chemistry

Example Input: Question: The Research Diagnostic Criteria (ICD-10) for the crisis of anguish: 
 Options:  <0> They are identical to the DSM-IV, there is no variation. <1> They are identical to those of DSM-IV, except that ICD-10 includes dry mouth and requires that at least one of the symptoms present be palpitations, sweating, tremors or dry mouth. <2> They differ in their entirety from those of the DSM-IV. <3> The ICD-10 Diagnostic Criteria do not require the appearance of a minimum of crisis. <4> The ICD-10 Diagnostic Criteria do not require a period of duration.
Example Output: psychology
