For question one, you can see that Robby moves east,
then he moves east again, he picks up this can,
he moves east, he picks up this can and then he moves south.
So, after he's done all that, the two squares above him,
these will be empty, this one will have a can,
and so all the directions around him will be empty
except for his current site, which will have a can.
So the correct answer is "C".
And his score, well he's picked up two cans,
and he hasn't done anything to get negative points, so his score is 20.
