Since one of the facts listed was that there are 5 houses in a row, we can make a chart that has the numbers 1-5 on the top and the different categories on the left (color of the house, nationality, beverage, brand of cigar, and pet).
Now let's look at clues 9 and 14.
Clue 9 says that the Norwegian is in house #1, so we can fill in the nationality for house #1.
Clue 14 says that the Norwegian lives directly next to the Blue house, which means that house #2 must be Blue, so we can fill that in on our chart as well.
