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: Indicate the correct answer regarding the forces that influence the filtration through the capillaries of the renal glomeruli (Glomerular Filtration) that takes place in the renal corpuscle: 
 Options:  <0> The hydrostatic pressure of the blood circulating in the glomerular capillaries favors filtration to the Bowman's capsule. <1> The colloid osmotic pressure due to the plasma proteins within the glomerular capillaries favors filtration towards the Bowman capsule. <2> The hydrostatic pressure of the liquid inside the Bowman's capsule favors filtration into Bowman's capsule. <3> The net gradient of the sum of these three pressures is 100 mm Hg in favor of filtration. <4> All the above are correct.
Example Output: nursery

Example Input: Question: To diagnose a situation of cardiorespiratory arrest, the correct sequence of assessment according to the recommendations of the Guide 2010 of the Spanish Council of Cardiopulmonary Resuscitation consists of: 
 Options:  <0> Check unconsciousness, check signs of life or presence of pulse, check if you breathe and open the airway. <1> Check unconsciousness, alert, open the airway and check if it breathes. <2> Check pulse, alert, open the airway, check unconsciousness, check if you breathe. <3> Open the airway, check unconsciousness, check for pulse or signs of life (cough, movement) and check if you breathe. <4> Open the airway, alert, check if you breathe, check presence of pulse or signs of life and check unconsciousness.
Example Output: nursery

Example Input: Question: In the determination of water hardness due to the presence of Ca2 + and Mg2 + ions, the titrant reagent is used: 
 Options:  <0> Methyl orange. <1> A standard solution of potassium chloride. <2> Black Eriochrome T. <3> A standard solution of ethylenediaminetetraacetic acid (EDTA). <4> A solution of AEDT previously standardized against a solution of potassium phthalate.
