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: Could a glass electrode be used as a reference electrode ?: 
 Options:  <0> Yes, if the glass electrode is a combined electrode. <1> Yes, if a mercury electrode is used as the indicator electrode. <2> No, since the glass electrode is a selective electrode. <3> No, because its foundation is not Nerstian. <4> Yes, if the determination is made in a buffered medium.
Example Output: chemistry

Example Input: Question: Graphite: 
 Options:  <0> It gives intercalation compounds with fluorine. <1> Reacts with sodium to give a covalent compound with C ̶ Na bond. <2> Reacts with sodium to give intercalation compounds that have the same distance between layers that pure graphite had. <3> Reacts with sodium to give intercalation compounds that are better electrical conductors than pure graphite. <4> It gives covalent compounds with bromine with C ̶ Br bond.
Example Output: chemistry
