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 a hospitalization unit, 15% of elderly people with dementia enter the year, most of them in very advanced stages. Pain is a frequent symptom in this type of patients. Point out the correct answer in patients with very advanced dementia: 
 Options:  <0> Untreated pain may manifest by agitation. <1> The Analog Visual Scale is the most appropriate for the assessment of pain due to its simplicity. <2> One-dimensional subjective scales are those recommended by experts to assess pain. <3> There are no specifically available scales designed to assess pain. <4> The administration of opioids for pain control is discouraged.

Output: nursery


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
