In this task, you are given a multiple-choice question about healthcare. Answer the question based on your information and classify your answers into '1', '2', '3', and '4'.

Input: Consider 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.

Output: 3


Input: Consider Input: Question: GnRH (ganodorelin) is a hypothalamic decapeptide that is secreted in a pulsatile manner. Lately a series of analogues have been developed that: 
 Options:  <1> All of them inhibit prolonged secretion of LH and FSH. <2> All of them are GnRH receptor agonists. <3> Goserelin and buserelin are antagonists of the GnRH receptor. <4> The prolonged treatment gives rise to a typical symptomatology of an excess of gonadal steroids. <5> GnRH agonists are contraindicated in prostate and breast cancer.

Output: 1


Input: Consider Input: Question: The Nernst equation: 
 Options:  <1> It is true both for reversible and highly irreversible galvanic cells. <2> It allows to calculate the electromotive force of a galvanic cell with only knowing the Gibbs energy standard of the chemical reaction of the cell. <3> It depends solely on the activities of the species that participate in the chemical reaction of the cell. <4> It relates the electromotive force of the cell with the activities of the species that participate in the chemical reaction of the cell and with the standard potential of the reaction. <5> It is independent of the number of electrons transferred in the electrochemical reaction of the cell


Output: 4
