Beggining the solution.

Collecting the data (piece of information);

Decide how is the system that will be solve the problem,

to do that we have to understand what kind of sets we have and are range of values;

and the answer is if have only one probably answer one that can't overlap the other.

This is the face of the range of values, and applying all the options.

The answer is before 1860 because have one part that doesn't overlap the others that are the time that is before the XIX century, but we have one problem say in the after 1830 we have the years that are in the XXI century, so for the comission they had the logic that one famous writer can't born in the XXI century, so Ok but this isn't exactly mathematical, can you imagine that we passes some half hours thinking why? So we notice that is very young for a writer, but this is the malice, and I am don't have all that malice, so I would notice the impossibility after submit my test and in home thinking about.
