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: Which of the following statements about the steady-state infusion of a drug is true? 
 Options:  <0> The concentration reached in steady state of equilibrium depends exclusively on the clearance. <1> The time necessary to reach the steady state of equilibrium depends on the volume of distribution. <2> The concentration reached in a steady state depends exclusively on the elimination half-life. <3> The concentration achieved in the steady state equilibrium depends on the clearance and the infusion rate. <4> The time required to reach the steady state of equilibrium depends on the clearance.

Output: pharmacology


Input: Consider Input: Question: Iron deficiency anemia is treated with oral or parenteral preparations: 
 Options:  <0> Only ferrous salts should be used orally. <1> Only ferric salts should be used orally. <2> Orally, the most appropriate form is the iron-dextran complex. <3> Orally, the treatment should last a maximum of fifteen days. <4> Only ferrous salts should be used parenterally.

Output: pharmacology


Input: Consider Input: Question: The magnitude of the steady state plasma concentration that is reached when a monocompartmental drug is administered in continuous perfusion is conditioned by: 
 Options:  <0> The time the perfusion is maintained. <1> The relationship between the rate of drug entry into the body (mg / h) and the elimination rate constant. <2> The relationship between the speed of entry to the body (mg / h) and the half-life of elimination of the drug. <3> The relationship between the speed of entry to the body (mg / h) and plasma clearance. <4> The administration of a rapid intravenous shock dose at the start of treatment.
