DIRECTIONS: Chооse the best аnswer fоr the question аt the bottom of the pаssage. The Truth about Dinosaurs [A] Dinosaurs are fascinating, but half-truths and myths about them are common. For years, scientists thought dinosaurs were just giant reptiles. Some dinosaurs were huge. But many were about the size of modern-day birds or dogs. Were dinosaurs warm- or cold-blooded? Paleontologists are still not sure. But they now believe a few dinosaurs were intelligent. Some smaller ones - like the two-meter Troodon - had fairly large brains.Was T. rex a powerful predator?[B] While some scientists think Tyrannosaurus rex was a powerful predator, others think the opposite is true. For example, in the movies T. rex is often a fast-moving giant. In reality, though, this dinosaur could not run fast. It was too large to move very quickly, so it probably moved about as fast as an elephant. T. rex also had very small arms and probably wasn't a powerful hunter. It may have been a scavenger instead, eating dead animals.Could dinosaurs fly?[C] Some reptiles, known as pterosaurs, were able to fly. But - even though they looked like them - these were not dinosaurs. Pterosaurs such as Tupuxuara could probably fly up to 16,000 kilometers nonstop. Scientists believe pterosaurs were actually very heavy. So they probably could not take off from the ground like birds. Instead, they first had to drop or throw themselves from trees in order to fly - much like bats.Are all dinosaurs extinct?[D] Dinosaurs completely disappeared about 66 million years ago. Scientists think they died out because of a global climate change: The Earth's temperature became too cold for them to survive. Now you can only see dinosaurs in museums. However, scientists believe that modern-day birds are, in fact, dinosaurs' descendants. If this is true, then dinosaurs' relatives are still walking - and flying - among us!QUESTION: What does the following sentence mean?However, they believe modern-day birds are, in fact, dinosaurs' descendants.
