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'.

Input: Consider Input: Question: What dose should you administer orally every 12 hours of a drug whose plasma clearance is equal to 1 L / h if you want to reach an average concentration of 10mg / L equilibrium? Assume complete bioavailability (F = 1): 
 Options:  <1> 120 mg. <2> 12 mg. <3> 200 mg. <4> 10 mg. <5> With this information it is not possible to estimate the dose necessary to reach this equilibrium concentration.

Output: 1


Input: Consider Input: Question: In the synthesis of DNA, the quinolones act: 
 Options:  <1> Joining the double helix and thus blocking the progress of the replication fork. <2> Interlacing in the double helix and thus causing errors in the transcription. <3> On DNA gyrase. <4> As nucleotide analogs that are incorporated into DNA. <5> About DNA polymerases.

Output: 3


Input: Consider Input: Question: Being the standard deviation and the number of data, the standard error of the mean, Sm, of a data set is: √𝑠 
 Options:  <1> 𝑆𝑚 = 𝑁 . <2> 𝑆𝑚 = 𝑠 𝑁 . 𝑁 <3> 𝑆𝑚 = √𝑠 . √𝑠 <4> 𝑆𝑚 = √𝑁 . 𝑠 <5> 𝑆𝑚 = √𝑁 .


Output: 5
