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: The secretion of the sebaceous glands is:
Options: <0> Merocrine <1> Apocrine <2> Paracrine <3> Holocrine <4> Endocrine

Output: biology

Input: Consider Input: Question: J. C, 85 years old, has a history of osteoporosis. A potential complication is fragility fracture, highlighting that:
Options: <0> A significant proportion of vertebral fractures are asymptomatic. <1> The Colles fracture is rare in people older than 65 years. <2> Fractures of the proximal third of the pertrochanteric femur are the less frequent fractures of the hip. <3> Half of the elderly who have a fall suffer a hip fracture. <4> The treatment of a proximal fracture of the femur will always be the prosthetic replacement.

Output: nursery

Input: Consider Input: Question: The calibration curves used in chemical analysis:
Options: <0> They represent the response of an analytical method to unknown concentrations of analyte. <1> They use standard samples that contain the solvent used in the analytical method, but without analyte. <2> They use a standard solution that allows knowing the response of the analytical method to the interfering species that exist in the reagents. <3> They are constructed by preparing samples of known analyte concentration (standards) and determining the response of the analytical procedure to these standards. <4> They are constructed using samples of unknown analyte concentration and measuring the response of the analytical procedure to them.
Output: pharmacology
