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: In the case of epileptic seizures, which of these data would allow us to state that it is hysterical crisis, and not epileptic seizures? 
 Options:  <1> The presence of apnea. <2> That the EEG record is normal. <3> They appear both when the individual is alone or accompanied. <4> Bites appear on the tongue or injuries due to falls. <5> Urinary incontinence appears.
Example Output: 2

Example Input: Question: 78-year-old man with poorly controlled rheumatoid arthritis (RA). A history of 2 admissions for heart failure and atrial fibrillation in the last 6 months. In current treatment with infliximab, prednisone, furosemide, enalapril, carvedilol and acenocoumarol. Enter again for biventricular heart failure clinic. The ECG showed atrial fibrillation at 102 bpm and advanced left bundle branch block. An echocardiogram shows biatrial dilation, thickening of the left ventricular wall with ejection fraction of 45% and restrictive pattern. The analytical highlights: Hb 10 gr / dL, creatinine 2.1 mg / dL (FG 20 mL / min), CRP 124 mg / L, rheumatoid factor 240 U / L, BNP 980 ng / L, proteinuria 4.8 g / 24h. What is the most likely diagnosis? 
 Options:  <1> Cardio-renal syndrome type 2. <2> Amyloidosis AA. <3> Myocarditis of giant cells. <4> Toxicity due to infliximab. <5> Membranous glomerulonephritis associated with RA.
Example Output: 2

Example Input: Question: To estimate the plasma clearance of a drug (CLIR) that presents a linear kinetic behavior and is excreted significantly in the urine, in a patient with renal failure (RI), it is necessary to know: 
 Options:  <1> Clearance of creatinine in the uremic patient (CLcrIR) and in individuals with normal renal function (CLcrFRN). <2> The renal clearance of the drug in patients with normal renal function (CLrFRN), CLcrIR and CLcrFRN. <3> The fraction of drug excreted in unaltered form in the urine (fr), the dose administered (D), CLrFRN, CLcrIR and CLcrFRN. <4> fr, CLcrIR and CLcrFRN and the plasma clearance of the drug in patients with normal renal function <5> fr, CLrFRN, CLcrIR, CLcrFRN and D.
