5 ........................................ 2
6 ........................................ 8
7 ........................................ 7
8 ........................................ 15
9 ........................................ 23
10 ........................................ 33
11 ........................................ 38
12 ........................................207
13 ........................................ 58

18 ........................................ 36
19 ........................................ 17
