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 Input:
Question: A 24-year-old boy who, after 3 days of high-risk sexual contact, has numerous pustular, small, very pruritic lesions that progress to minute erosions affecting the entire glans and inner face of the prepuce. Indicate which is, among the following, the most probable diagnostic orientation:
Options: <0> Genital candidiasis <1> Chancroid. <2> Secondary syphilis <3> Balanitis by Trichomonas. <4> Fungal infection by dermatophytes.

Ex Output:
medicine

Ex Input:
Question: If in an epidemiological study, the participating population has voluntariness as an inclusion criterion, the validity of the results are subject to a bias of:
Options: <0> Information. <1> Confusion. <2> Selection. <3> Interpretation. <4> Publication.

Ex Output:
nursery

Ex Input:
Question: A particle charged in solution moves when it is placed in an electric field. The speed acquired by the solute under the influence of the applied voltage is the product of the apparent mobility of the solute and the applied field. With regard to this mobility, it can be stated that:
Options: <0> A neutral particle of small size will have a smaller mobility than a neutral one of large size. <1> A macromolecular polymer will have greater mobility than the corresponding monomer. <2> A large particle with a small charge will have great mobility. <3> A small particle of great load will have great mobility. <4> A charged micelle will have less mobility than another micelle of the same size but neutral.

Ex Output:
chemistry
