Two fathers and two sons went fishing one day. They were there the whole day and only caught 3 fish. One father said, that is enough for all of us, we will have one each. How can this be possible? 

There was the father, his son, and his son’s son. This equals 2 fathers and 2 sons: the grandfather, the father and the son.

It is great Paula J., Alícia and Raquel. Very good job for you. Congratulations. And thanks to Adrián and Carla for your effort.

Have a look to your score. The leader has changed: English score
