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: If a sample of size 100 has a standard deviation of 10, its typical error is:
Options: <1> 10 <2> 100 <3> 0.1 <4> one. <5> There is not enough data to calculate it.

Ex Output:
4

Ex Input:
Question: The presence of foreign bodies such as small buttons, sunflower seeds, etc., in the respiratory tract in young children is a relatively frequent accident. Point out the signs that appear when these objects are lodged in the lower respiratory tract:
Options: <1> Episodes of cough, hoarseness and dyspnea. <2> Chronic cough, hypoventilation on auscultation, signs of infection. <3> Asphyxia, dyspnea, cyanosis, respiratory failure. <4> Fever, cough and dysphonia. <5> Tachypnea, increased respiratory effort.

Ex Output:
2

Ex Input:
Question: The deviation of Beer's law by the use of non-monochromatic radiation can lead to deviations from linearity when representing absorbance versus concentration due to:
Options: <1> Different molar absorptivities of the absorbent species. <2> Very similar molar absorptivities of the radiations of the polychromatic beam. <3> That the radiant power of the incident beam is modified. <4> That the use of a polychromatic beam always implies significant differences with respect to a monochromatic one. <5> That the relation of incident and transmitted powers is different.

Ex Output:
