Why is the picture illustrating "a porta" showing a gate when we're taught that it means "door" and "o portão" means gate? I understand that there might be an overlap, that "porta" can mean both things, but shouldn't it make things clearer if the main picture would be a door? And the secondary pictures (that are shown in the look-at-3-pictures-and-choose-the-article practices) could be of gates and main entrances and such. Since we're taught "o portão at this early stage, I mean"
I know... A lot of the picture choices are weird anyway ;)
