Note that this game is probably more efficiently done without splitting into sub-game-boards. According to our rule of thumb for splitting, the fewer the sub-game-boards and the more questions, the more we want to split. Here, we have four regular questions of which two give us additional premises. Looking at the split boards, we have at minimum four. On balance, it's probably better not to split.
Contrast with Game 3 from this set. There we have only two sub-game-boards yet we have six regular questions. Splitting is the right approach.
Note:
Question 3, answer (A) is shown as "T 1", which is a mistake. It should have been shown as "T 2". which is what is actually written on the test. Either way, (A) is still wrong.
