On an exotic island you were bitten by a venomous snake.
Fortunately, in the nearest settlement there was a doctor. He examined the wound and gave four pills: two antidotes and two catalysts accelerating the effect of the antidote.
It is necessary to take medications in a strictly established order: immediately take one antidote and at the same time one catalyst. One without the other will not work. And before going to bed do all the same.
It would seem that you are saved. However, suddenly you find out that you put all the pills in a small vial where they all got mixed.
You cannot drink four pills at once. Taking two randomly selected pills is dangerous too.
What decision to take to be saved?
