A gecko, a lizard, a koala, a tapir, a giraffe, and a cow. He hasn’t labeled he test tubes containing the saliva f the animals. On the left is a table which four of the test tubes are one. On the right is a table which two of the test tubes are on. The lizards saliva is poisonous. The lizard and gecko test tubes are on the same table. The test tubes on the left are labelled 1, 2, 3, and 4. The gecko spit will not override the lizard poison. The lizard and gecko saliva are not right beside each other. You don't know where the cow test tube is. You know that the cow saliva is in 2 or 3 however. You know that the lizard test tube is not to the right of the cow. You only have time to drink two test tubes, which side do you run toward and which test tubes do you drink?
