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.

[EX Q]: Question: Jaundice (yellowing of the skin and mucous membranes due to increased levels of bilirubin) may be of cholestatic origin (pathway obstruction) or hepatocellular damage. Indicate the correct answer: 
 Options:  <0> In cholestatic jaundice we observed: persistent alanine aminotransferase (ALT) increase without elevation of gamma glutamyltransferase (GGT). <1> In hepatocellular jaundice there is a slight increase in GGT (<5 times the upper limit of reference) and a large increase in ALT (> 10 times the upper limit of reference). <2> In cholestatic jaundice, a decrease in direct bilirubin and prothrombin time is observed. <3> In hepatocellular jaundice, a decrease in alkaline phosphatase and activated partial thromboplastin time is observed. <4> In both jaundices we can observe a clear decrease in aspartate aminotransferase (AST).
[EX A]: pharmacology

[EX Q]: Question: The negative feedback regulation of thyroid hormone is as follows: 
 Options:  <0> High concentrations of circulating free T3 and T4 that elevate HRT. <1> High concentrations of circulating free T3 and T4 that raise TSH. <2> High concentrations of circulating free T3 and T4 that decrease TRH. <3> Decreased TRH that elevates TSH. <4> Decreased TSH that elevates HRT.
[EX A]: nursery

 Options:  <0> Smooth muscle fibers. <1> Bipolar neurons of the retina. <2> Skeletal striated muscle fibers. <3> Cardiac muscle fibers. <4> Ganglion neurons of the retina.
