Example Input: Question: The reaction conditions for transforming nonanamide into octanamine and carbon dioxide are: 
 Options:  <1> H2, metallic catalyst. <2> Excess of CH3I, K2 CO3. <3> Cl2, NaOH, H2O. <4> LiAlH4, diethyl ether and then hydrolysis. <5> CH2N2, diethyl ether.
Example Output: 3

Example Input: Question: The INR (international normalized ratio) of a patient with chronic atrial fibrillation treated with Acenocoumarol is 4. This result indicates that: 
 Options:  <1> The appearance of ventricular arrhythmias should be controlled. <2> The patient is correctly anticoagulated. <3> Anticoagulation with heparin is more indicated. <4> There is a risk of thrombus formation. <5> Signs of bleeding should be assessed.
Example Output: 5

Example Input: Question: With regard to the alkaloids derived from ergoline: 
 Options:  <1> They can be obtained by fermentation of pure Claviceps purpurea cultures and derived from phenylalanine and isoprene obtained by the mevalonic acid route (MVA). <2> They can be obtained by fermentation of pure cultures of Claviceps purpurea and derived from tyrosine and isoprene obtained by the DOXP route. <3> They can be obtained by fermentation of pure cultures of Claviceps purpurea and derived from tryptophan and isoprene obtained by the route of mevalonic acid (MVA). <4> They can be obtained by rye infection with Claviceps purpurea spores and derived from tryptophan and isoprene obtained by the DOXP route. <5> They can be obtained by wheat infection with Claviceps purpurea spores and derived from tyrosine and isoprene obtained by the mevalonic acid (MVA) route.
