Answer the questions at the end based on the text.

Birds (Aves) are a group of endothermic vertebrates, characterised by feathers, toothless beaked jaws, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton. Birds live worldwide and range in size from the 5 cm (2 in) bee hummingbird to the 2.75 m (9 ft) ostrich. They rank as the class of tetrapods with the most living species, at approximately ten thousand, with more than half of these being passerines, sometimes known as perching birds or, less accurately, as songbirds.

The fossil record indicates that birds are the last surviving dinosaurs, having evolved from feathered ancestors within the theropod group of saurischian dinosaurs. True birds first appeared during the Cretaceous period, around 100 million years ago. DNA-based evidence finds that birds diversified dramatically around the time of the CretaceousPaleogene extinction event that killed off all other dinosaurs. Birds in South America survived this event and then migrated to other parts of the world via multiple land bridges while diversifying during periods of global cooling. Primitive bird-like dinosaurs that lie outside class Aves proper, in the broader group Avialae, have been found dating back to the mid-Jurassic period. Many of these early "stem-birds", such as Archaeopteryx, were not yet capable of fully powered flight, and many retained primitive characteristics like toothy jaws in place of beaks, and long bony tails.

DirecTV (stylized as DIRECTV or simply DTV) is an American direct broadcast satellite service provider based in El Segundo, California and is a subsidiary of AT&T. Its satellite service, launched on June 17, 1994, transmits digital satellite television and audio to households in the United States, Latin America and the Caribbean. Its primary competitors are Dish Network and cable television providers. On July 24, 2015, after receiving approval from the United States Federal Communications Commission and United States Department of Justice, AT&T acquired DirecTV in a transaction valued at $48.5 billion.

DirecTV provides television and audio services to subscribers through satellite transmissions. Services include the equivalent of many local television stations, broadcast television networks, subscription television services, satellite radio services, and private video services. Subscribers have access to hundreds of channels, so its competitors are cable television service and other satellite-based services.

Most subscribers use reception antennas which are much smaller than the first generation antennas, which were typically a few yards (meters) across. Advances in antenna technology, including fractal antennas, have allowed a general reduction in antenna size across all industries and applications. Receiving equipment includes a satellite dish, an integrated receiver/decoder and a DirecTV access card, which is necessary to operate the receiver/decoder.

beep ...beep ... There went the bell! Robbie opened his eyes. He had been sitting in the room for a whole day, and now it was time for him to do something. Robbie looked out of the window. It was still snowing heavily and there was ice on the window. It was another cold day. Robbie was told to turn the heat on before the family got home. And he _ Then Robbie was told to do some cleaning work at once. It was an easy job for him, but a tough one for his master, Helen. He kept on working until every room was clean and tidy. For now, he had to cook supper for the family. The first thing Robbie did was to get the big pot in the kitchen. Then he put some water in the pot and put it on the stove. He used one of his hands to cut up a chicken and added the pieces to the water to make a good soup. Then he got some tomatoes, cabbages and carrots to make a vegetable salad. At ten past eight he laid the table. Then he put some bread, the chicken soup and the salad on it. What a sweet smell! The moment he turned on the lights, the whole family came home. "The soup smells great, Victor," said Helen. "You really know how to tell Robbie what to do." Robbie is one robot that really saves the family a lot of work.
