This question says that the hickory is planted on lot 2. Whenever a question gives you a new rule, you should draw it and then combine the new rule with the existing rules.
Rule 1 mentions the hickory. The hickory must go with the oak and exactly one other tree:
The vertical line by lot 2 shows that it’s full.
Next, consider the other rules. We know that lot three needs more trees than lot one. There are only four trees left. So we need to place three trees in lot three and one tree in lot one:
Next consider the other rules. They are:
- Maple and Walnut aren’t together.
- One of L/W goes in lot one.
- One of M/O goes in lot two.
The third one is affected by our setup. The oak is already in lot two, so the maple can’t go there. And the maple can’t go in lot one, because one of L/W must go there.
So the maple must go in lot three:
Whenever you make an extended deduction like this, you should check the answers, because this type of deduction usually solves the question instantly.
B is CORRECT. The maple must go in lot three. A, C and D could be true but don’t have to be. E must be false.
