Hey Nina,

If you read the posting on the diagram, you'll see that there are very few upfront inferences that one can make on this game. This means that most of the questions are conditional (they add a new condition, to help you make some inferences). This question, however, is unconditional, so it's a tough one. What you have to assume is that one of these will start you down a logical path. Just quickly draw out what happens and see if a rule gets broken.

(A) No rules broken, and we now have plenty of space to fit the rest of the reptiles. Unlikely to be problematic.

(B) No rules broken, and we still have up to 8 slots to put the remaining 6 reptiles. (If you don't understand what I mean, go download the diagram as provided in the Diagram posting).

(C) Same as (A).

(D) This is interesting, because we now only have 6 slots in which to put 6 reptiles.

(E) Same as (D).

In other words, (D) and (E) should jump out at you as being potentially problematic, because they force you to put a reptile in all of the remaining slots. So let's look at them more closely.

(D) The first slot ate up a male snake, so what do we have left to place? 3 snakes and 3 lizards. How could that be done?

OR

SLL

Either way, we break the rule that we can't have a snake and a lizard in the same house. This isn't possible, so it's the correct answer.

(E) The second slot ate up a lizard, so what do we have left to place? 2 lizards and 4 snakes. How could that be done?

We can do it without breaking the rule! Yay!

Hope that helps!
