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'.

Ex Input:
Question: The Arrhenius equation: 
 Options:  <1> It relates the speed of a chemical reaction with the so-called constant velocity and with the concentrations of the reactants raised to their stoichiometric coefficients. <2> It relates the constant of speed of a chemical reaction with the energy of activation of said reaction, so that if the energy, of activation is high the reaction is fast. <3> It is only fulfilled for unimolecular reactions. <4> It relates the speed constant to the temperature through the activation energy and the pre-exponential factor. <5> It allows to obtain the activation energy of an elementary reaction by only representing the decimal logarithm of the temperature versus the inverse of the reaction time.

Ex Output:
4


Ex 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

Ex Output:
4
