TASK DEFINITION: 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.
PROBLEM: Question: A 72-year-old man with a pathological fracture in the left femur goes to the Emergency Department. After the surgical intervention, the diagnostic study was performed to find out the underlying pathology with the following findings: hemoglobin 9.5 g / dl, total protein 11 g / dl, (VN: 6-8 g / dl), serum albumin 2 g / dl, (VN 3.5-5.0 g / dl), beta 2 microglobulin 6 mg / l (VN 1.1-2.4 mg / l), serum creatinine 1.8 mg / dl (VN: 0 , 1-1.4 mg / dl). Indicate what would be the diagnostic tests necessary to confirm the most probable diagnosis: 
 Options:  <0> Radiological bone series and bone marrow aspiration. <1> Serum and urinary electrophoresis and renal function tests. <2> Bone marrow aspirate and serum calcium concentration. <3> Bone marrow aspiration and serum and urinary electrophoresis. <4> Biopsy of the pathological fracture and radiological bone series.

SOLUTION: medicine

PROBLEM: Question: In a three-point test crossover study, a negative interference indicates that: 
 Options:  <0> More double crossings have occurred than expected. <1> There have been fewer double crossings than expected. <2> The match coefficient is less than 1. <3> A simple crossover decreases the likelihood of a double crossover occurring. <4> There have been fewer simple cross-links than expected.

SOLUTION: biology

PROBLEM: Question: A pediatrician wants to study overweight in children of 14 years, according to the values ​​of the BMI (body mass index). To estimate the necessary sample size, it proposes a confidence level of 95% and a precision of 1 unit of BMI. What other parameters do you need to know to determine the sample size? 
 Options:  <0> The average BMI in the population. <1> The variance of the BMI. <2> The mean and standard deviation of the BMI. <3> The size of the population and the average BMI. <4> The standard deviation of the BMI and the population size.
