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'.

Example Input: Question: The surgical treatment of COPD, or lung volume reduction surgery, is currently a therapeutic weapon more within the multidisciplinary treatment of it. Which of the following statements is correct? 
 Options:  <1> The indication for surgical treatment will be in those patients who have moderate / severe congestive heart failure at the same time. <2> The presence of a pulmonary artery systolic pressure lower than 45 is an absolute contraindication. <3> COPD with emphysematous predominance in lower and middle lobes associated with pleural pathology is associated with better results. <4> The presence of a diffuse distribution of emphysema with FEV1> 20% and DLCO <20% are indicators of good prognosis. <5> Pre-surgical rehabilitation along with the distribution of emphysema in the upper lobes and the ability to perform postoperative physical exercise makes the results of the surgery beneficial.
Example Output: 5

Example Input: Question: Which of the following statements is true with respect to the alkaloid morphine ?: 
 Options:  <1> It is an isoquinoline alkaloid extracted from straw of Papaver somniferum. <2> It is a benzylisoquinol alkaloid extracted from latex of Papaver somniferum. <3> It is a tracheal alkaloid extracted from leaves of Papaver somniferum. <4> It is a quinolizidine alkaloid extracted from capsules of Papaver somniferum. <5> It is a pyrrolidinic alkaloid extracted from roots of Papaver somniferum.
Example Output: 2

Example Input: Question: In the homogeneous nucleation: 
 Options:  <1> If the solid particles formed under solidification have a radius less than the critical radius, the energy of the system will be lower if its size increases. <2> If the solid particles formed under solidification have a radius smaller than the critical radius, the energy of the system will be lower if it is redissolved. <3> If the solid particles formed under solidification have a radius greater than the critical radius, the energy of the system will be lower if it is redissolved. <4> If the solid particles formed under solidification have a radius equal to the critical, the energy of the system will be lower if it is redissolved. <5> There is no relationship between the critical radius and the tendency to grow in size or redissolve.
Example Output:
2
