QUESTION TYPE: Must Be False
FACTS:
- The southern part of a certain area was covered by water during the Cretaceous.
- Dinosaurs only lived on land.
- Plesiosaurs lived in water, during the cretaceous only.
- No single dinosaur lived during the whole Mesozoic.
ANALYSIS: Remember that we’re looking for something that has to be false. All of the wrong answers could be true or must be true.
___________
- We have no idea what the northern half was like. Maybe it was also covered by water.
- We know dinosaurs didn’t live in the southern half. Plesiosaurs might have, since they were aquatic.
- This has to be true. Plesiosaurs lived only during the Cretaceous.
- Same as A. We have no idea what the northern half was like. Maybe it was covered by land.
- CORRECT. This can’t be true. The southern half was covered by water during the cretaceous, so dinosaurs couldn’t have lived there at that time.
