Only for geniuses!

Social networks have been very useful today, have even managed to overthrow a dictatorship, as happened in Egypt in 2013, when several people called to demonstrate against the then President Mohamed Morsi, who had been ruling for more than 30 years. This same year, we have seen how the use of social networks, in the presidential elections in Mexico, made a big difference in favor of the winning candidate. Although you have to be careful and learn to differentiate what is true or false, because many times you share ideas or images without even corroborating the origin of them. In my case, I have seen how they allow society to bring information that was previously privileged, and, as in the case of this book, to bring ingenuity problems that allow us to keep our minds active and in good condition. This is already the second volume of the series that began exposing the problems that during the past years reached the level of "viral". Now we have selected from among them, those that have been labeled as "Only for Geniuses" and that appear from daily publications, even in the big news chains. I hope you enjoy solving each exercise as much as I did, and remember to go to the solution of each one until you have managed to find it, proving to be a genius!
