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 Q]: Question: The Arrhenius equation: 
 Options:  <1> It relates the speed of a chemical reaction with the so-called constant velocity and with the concentrations of the reactants raised to their stoichiometric coefficients. <2> It relates the constant of speed of a chemical reaction with the energy of activation of said reaction, so that if the energy, of activation is high the reaction is fast. <3> It is only fulfilled for unimolecular reactions. <4> It relates the speed constant to the temperature through the activation energy and the pre-exponential factor. <5> It allows to obtain the activation energy of an elementary reaction by only representing the decimal logarithm of the temperature versus the inverse of the reaction time.
[EX A]: 4

[EX Q]: Question: A 75-year-old man who reported decreased visual acuity in his right eye of two weeks of evolution. In the fundus examination, soft drusen and serous detachment at the level of the macula are seen. What treatment is currently the most indicated for this disease? 
 Options:  <1> Focal photocoagulation with laser. <2> Photodynamic therapy. <3> Intravitreal injections of anti-angiogenic drugs. <4> Posterior vitrectomy. <5> Observation.
[EX A]: 3

[EX Q]: Question: When distinguishing alcoholic patients with Korsakoff Syndrome from patients with alcoholic dementia, we can take into account that: 
 Options:  <1> In patients with Korsakoff syndrome, the IQ measurement remains relatively intact, while this measure is impaired in the case of alcoholic dementia. <2> Patients with dementia do not have memory problems, while those with Korsakoff syndrome do. <3> In cases of dementia, amnesia appears as the first and most relevant symptom. <4> In the case of Korsakoff Syndrome there is no anterograde amnesia (ability to acquire new information). <5> In the case of dementia, the skills learned remain intact, whereas in Korsakoff Syndrome they are very deteriorated.
