Example Input: Question: For which disorder is the technique of fading stimulated frequently used? 
 Options:  <1> Enuresis <2> The selective mutism. <3> Childhood asthma <4> Posttraumatic stress disorder secondary to sexual abuse. <5> The encopresis.
Example Output: 2

Example Input: Question: From a microbial growth control point of view, it can be stated that: 
 Options:  <1> Pasteurization is a method of sterilization for liquid substances. <2> The overpressure is what kills the microorganisms when the autoclave is used. <3> Antiseptic agents are applied to living tissues. <4> The autoclave is the recommended method for sterilizing thermosensitive liquids. <5> The use of ultraviolet radiation is due to its high penetration power.
Example Output: 3

Example Input: Question: The equation of speed of a chemical reaction: 
 Options:  <1> It must be determined from kinetic measurements and can not be deduced directly from the stoichiometry of the reaction. <2> Allows the units of s-1 (s = second) to be assigned to the velocity constant. <3> It depends on the total reaction order that, in turn, is obtained from the stoichiometric coefficients of the products. <4> Report in detail about the reaction mechanism. <5> It depends on the experimental conditions of the process.
Example Output:
