In species such as the red-back spider, the black widow spider, the praying mantis, and the scorpion, the female commonly eats the male after mating. Another widespread form of cannibalism is size-structured cannibalism, in which large individuals consume smaller ones. Octopus, bats, toads, fish, monitor lizards, salamanders, crocodiles, spiders, crustaceans, birds, mammals, and a vast number of insects have all been observed to engage in size-structured cannibalism. Yet another common form of cannibalism is infanticide. Classic examples include the chimpanzees, where groups of adult males have been observed to attack and consume their infants; and lions, where adult males commonly kill infants when they take over a new harem after replacing the previous dominant males. Also, gerbils and hamsters eat their young if they are stillborn, or if the mothers are especially stressed.

Almost two thousand years ago, when Julius Caesar landed on the island we now know as Britain, the English language did not exist. Five hundred years later, a form of English called Old English (which was so different from modern English that you and I couldn’t even understand it) had emerged, and was spoken by only a few thousand people. By the late sixteenth century, when William Shakespeare was writing his greatest plays, English was the native language of five to seven million British people, but was not yet used anywhere outside of Britain itself. In the four hundred years since then, English-speakers such as the Scottish, the Irish, the Americans, and many others have carried their language and culture to all parts of the globe, and English has become the most widely spoken, written, and far-reaching language in human history. Today English is used by roughly a billion people, more than half of whom have learned it as a second language. It has become a global language of business as well as technology, appearing in 75 percent of the world’s mail and 80 percent of the information stored in the world’s computers.

In 1818, British author Mary Shelley wrote what was probably the world’s first science- fiction novel, Frankenstein. In the novel, scientist Victor Frankenstein sets out to create a man by piecing together the remains of corpses gathered in charnel houses. While his efforts prove successful, Victor is revolted by the ugliness of the man he has created and abandons it. Enraged by his creator’s abandonment, the creature becomes a killer and wreaks havoc upon all those Victor holds dear. Victor goes in pursuit of his creation, and both eventually die in the barren wastes near the North Pole. In 1886, Robert Louis Stevenson published The Strange Case of Dr. Jekyll and Mr. Hyde. In this story, a mild- mannered London physician, bored with his life, creates a potion that when swallowed frees his evil twin, Edward Hyde. A living embodiment of Jekyll’s repressed desires, Hyde runs wild, kills a member of Parliament, becomes a fugitive, and eventually destroys both himself and his creator. More recently, American author Michael Crichton’s Jurassic Park tells what happens when modern scientists clone dinosaurs using the DNA found in the remains of prehistoric mosquitoes. Predictably enough, the dinosaurs run out of control, killing the organizers of the theme park which was to “safely” display them, while two paleontologists are among those who narrowly escape with their lives.
Chооse the sentence thаt best expresses the implied mаin ideа оf the paragraph below. Far from being America’s favorite food, during the early 1900s, hamburgers were considered “food for the poor.” Restaurants generally didn’t sell them. Burgers were served at lunch carts parked near factories, at circuses, and at carnivals. It was widely believed that ground beef was made from rotten old meat full of chemical preservatives. In the mid- 1920s, however, a man named Walt Anderson set out to defend the hamburger from its many critics. Walt loved burgers and opened a small restaurant devoted to selling them—the first White Castle—in Wichita, Kansas. Walt grilled the burgers right in front of his customers, so they could see for themselves that the meat and the equipment were clean. He also supported an unusual experiment at the University of Minnesota. For thirteen weeks, a medical student there consumed nothing but White Castle hamburgers and water. When the student not only survived the experiment but also seemed pretty healthy, people started to view hamburgers in a new light—as wholesome, not deadly.
Chооse the sentence thаt best expresses the implied mаin ideа оf the paragraph below. Working at home is convenient and flexible and can be less stressful than daily commuting. It can benefit employers (who need less space), employees (who save on clothing and transportation), and entrepreneurs (who save on office expenses). However, it is not for everyone: it requires enough initiative, independence, and self-confidence to work without supervision. Some home workers feel isolated or have trouble concentrating in the presence of such distractions as television, the refrigerator, and young children. Also, employees who work at home may lose fringe benefits, such as health insurance, and the protection of laws guaranteeing fair labor standards and working conditions.
The functiоn cоupоn_cаlculаtor tаkes one parameter: age. It should return a string with a specific discount based on the user's age. Users below the age of 18's discount should be their age as a percent. Users below the age of 65's discount should be 50% off. All other users should receive a discount of 70% off. All users will receive a string that will include their age and discount. For example: coupon_calculator(25) should return "25 years old? Here is your 50% discount." However, the function contains multiple logic and/or syntax errors. Identify and correct the errors in the code snippet so the function works as intended. You cannot change entire chunks of code nor rewrite it completely. Mention the line number where the error is, what the error is, and the correction. 1. def coupon_calculator(age):2. discount = 1003. if age < 18:4. discount = age5. else if age < 65:6. discount /= 27. else:8. discount == 709. return f"age years old? Here is your {discount}% discount."
