MCQ-> In the following questions, you have two passages with 5 questions in each passage. Read the passages carefully and choose the best answer top each question out of the four alternatives. A dolphin is an aquatic mammal. Dolphins are extremely intelligent and sociable animals and have their own way to communicate with each other using special sounds. Although they are often mistaken for fis, dolphins are actually mammals. They are members of the Cataca (pronounced se-ayshia) family, which also contains whales and porpoises. One way of telling the difference between a cetacean and a fish is by looking at their tails. You can tell a cetacean because their tail fins (called flukes) are horizontal and move up and down. Fish have vertical tails which move from side to side. A dolphin’s body is designed to help them move quickly and easily through water. On its back is a curved dorsal fin and on each side of the dolphin is a pectoral fin. The bump on a dolphins head is known as the melon. They trap their prey by using their teeth. Dolphins use a type of sonar to detect where objects are around them. This is called echolocation. Echolocation works when a dolphin bounces a high pitched sound off an object and then listens for the echo to come back. It is a very useful way for dolphins to find food and navigate. Dolphins communicate with each other through clicks, squeaks and whistles. They use these special sounds to greet each other and to indicate if they are in distress. Dolphins live in the sea, but they can’t breathe under water. They breathe through a blowhole and have to come up for air every 15 minutes.Cetacea does not include:
