Put the verb in brackets in a suitable form, using a negative where necessary.

The extinction of the dinosaurs

The dinosaurs probably became extinct after a giant asteroid hit the Earth about 65 million years ago. But what _________(happen) if this asteroid __________(miss)? Scientists believe that in this case, dinosaurs _______(continue) to dominate the Earth, and that modern animals _______(probably exist). Instead of elephants and lions and so on, there _______(be) different types of dinosaurs, because the animals we have now simply _______(be able) to evolve. Some scientists have even suggested that dinosaurs ________(develop) along the same lines as human beings, but this is a minority view. The general view is that perhaps dinosaur brains _______(grow) larger, but if they _______(exist) today, dinosaurs ________(change) very much in general, and _________(look) much the same. The prospects for human beings would not be so good, however. If the asteroid _______(collide) with the Earth, there _________(probably be) any humans alive today. When the asteroid disaster wiped out the dinosaurs, it gave mammals the advantage. Without that space collision, mammals _______(stand) much chance against the dominant dinosaur species.
