A microwave oven (commonly referred to as a microwave) is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. This induces polar molecules in the food to rotate and produce thermal energy in a process known as dielectric heating. Microwave ovens heat foods quickly and efficiently because excitation is fairly uniform in the outer 25–38 mm  (1–1.5 inches) of a homogeneous, high water content food item.
The development of the cavity magnetron in the UK made possible the production of electromagnetic waves of a small enough wavelength (microwaves). American engineer Percy Spencer is generally credited with inventing the modern microwave oven after World War II from radar technology developed during the war. Named the "Radarange", it was first sold in 1946.
Raytheon later licensed its patents for a home-use microwave oven that was introduced by Tappan in 1955, but it was still too large and expensive for general home use. Sharp Corporation introduced the first microwave oven with a turntable between 1964 and 1966. The countertop microwave oven was introduced in 1967 by the Amana Corporation. After microwave ovens became affordable for residential use in the late 1970s, their use spread into commercial and residential kitchens around the world.

Vegetarianism is the practice of abstaining from the consumption of meat (red meat, poultry, seafood, and the flesh of any other animal), and may also include abstention from by-products of animal slaughter.Vegetarianism may be adopted for various reasons. Many people object to eating meat out of respect for sentient life. Such ethical motivations have been codified under various religious beliefs, as well as animal rights advocacy. Other motivations for vegetarianism are health-related, political, environmental, cultural, aesthetic, economic, or personal preference. There are variations of the diet as well: an ovo-lacto vegetarian diet includes both eggs and dairy products, an ovo-vegetarian diet includes eggs but not dairy products, and a lacto-vegetarian diet includes dairy products but not eggs. A vegan diet excludes all animal products, including eggs and dairy. Avoidance of animal products may require dietary supplements to prevent deficiencies such as vitamin B12 deficiency, which leads to pernicious anemia. Psychologically, preference for vegetarian foods can be affected by one's own socio-economic status and evolutionary factors.Packaged and processed foods, such as cakes, cookies, candies, chocolate, yogurt, and marshmallows, often contain unfamiliar animal ingredients, and so may be a special concern for vegetarians due to the likelihood of such additives. Feelings among vegetarians vary concerning these ingredients. Some vegetarians scrutinize product labels for animal-derived ingredients, such as cheese made with rennet, while other vegetarians do not object to consuming them or are unaware of their presence.Semi-vegetarian diets consist largely of vegetarian foods but may include fish or poultry, or sometimes other meats, on an infrequent basis.

The wedding of Prince Charles and Lady Diana Spencer took place on Wednesday 29 July 1981 at St Paul's Cathedral in London, United Kingdom. The groom was the heir apparent to the British throne, and the bride was a member of the Spencer family.
The ceremony was a traditional Church of England wedding service. The dean of St Paul's Cathedral, Alan Webster, presided at the service, and the archbishop of Canterbury, Robert Runcie, conducted the marriage. Notable figures in attendance included many members of other royal families, republican heads of state, and members of the bride's and groom's families. After the ceremony, the couple made the traditional appearance on the balcony of Buckingham Palace. The United Kingdom had a national holiday on that day to mark the wedding. The ceremony featured many ceremonial aspects, including use of the state carriages and roles for the Foot Guards and Household Cavalry.
Their marriage was widely billed as a "fairytale wedding" and the "wedding of the century". It was watched by an estimated global TV audience of 750 million people.

Silence is the absence of ambient audible sound, the emission of sounds of such low intensity that they do not draw attention to themselves, or the state of having ceased to produce sounds; this latter sense can be extended to apply to the cessation or absence of any form of communication, whether through speech or other medium.Sometimes speakers fall silent when they hesitate in searching for a word, or interrupt themselves before correcting themselves. Discourse analysis shows that people use brief silences to mark the boundaries of prosodic units, in turn-taking, or as
reactive tokens, e.g., as a sign of displeasure, disagreement, embarrassment, desire to think, confusion, and the like.  Relatively prolonged intervals of silence can be used in rituals; in some religious disciplines, people maintain silence for protracted periods, or even for the rest of their lives, as an ascetic means of spiritual transformation.


== Silence as a rhetorical practice ==
Silence may become an effective rhetorical practice when people choose to be silent for a specific purpose. It has not merely been recognized as a theory but also as a phenomenon with practical advantages. Rhetorical silence cannot be explained since it happens when lack of communication is not expected. When silence becomes rhetorical, it is intentional since it reflects a meaning. Rhetorical silence targets audience rather than the rhetorician. One of those advantages of silence is to achieve various types of rhetorical and literacy practices. There are always some meanings, intentions, and goals that cannot be expressed linguistically in words and there are always voices that cannot be raised through sounds, rather they are all reflected through silence.

McDonald's Corporation is an American fast food company, founded in 1940 as a restaurant operated by Richard and Maurice McDonald, in San Bernardino, California, United States. They rechristened their business as a hamburger stand, and later turned the company into a franchise, with the Golden Arches logo being introduced in 1953 at a location in Phoenix, Arizona. In 1955, Ray Kroc, a businessman, joined the company as a franchise agent and proceeded to purchase the chain from the McDonald brothers. McDonald's had its previous headquarters in Oak Brook, Illinois, but moved its global headquarters to Chicago in June 2018.McDonald's is the world's largest restaurant chain by revenue, serving over 69 million customers daily in over 100 countries across 37,855 outlets as of 2018. Although McDonald's is best known for its hamburgers, cheeseburgers and french fries, they feature chicken products, breakfast items, soft drinks, milkshakes, wraps, and desserts. In response to changing consumer tastes and a negative backlash because of the unhealthiness of their food, the company has added to its menu salads, fish, smoothies, and fruit. The McDonald's Corporation revenues come from the rent, royalties, and fees paid by the franchisees, as well as sales in company-operated restaurants. According to two reports published in 2018, McDonald's is the world's second-largest private employer with 1.7 million employees (behind Walmart with 2.3 million employees). As of 2020, McDonald's has the ninth-highest global brand valuation.

Lettuce (Lactuca sativa) is an annual plant of the daisy family, Asteraceae. It is most often grown as a leaf vegetable, but sometimes for its stem and seeds.  Lettuce is most often used for salads, although it is also seen in other kinds of food, such as soups, sandwiches and wraps; it can also be grilled. One variety, the celtuce (asparagus lettuce) (t: 萵苣; s: 莴苣; woju), is grown for its stems, which are eaten either raw or cooked. In addition to its main use as a leafy green, it has also gathered religious and medicinal significance over centuries of human consumption.  Europe and North America originally dominated the market for lettuce, but by the late 20th century the consumption of lettuce had spread throughout the world.  World production of lettuce and chicory for  2017 was 27 million tonnes, 56% of which came from China.Lettuce was originally farmed by the ancient Egyptians, who transformed it from a plant whose seeds were used to create oil into an important food crop raised for its succulent leaves and oil-rich seeds. Lettuce spread to the Greeks and Romans; the latter gave it the name lactuca, from which the English lettuce is derived. By 50 AD, many types were described, and lettuce appeared often in medieval writings, including several herbals. The 16th through 18th centuries saw the development of many varieties in Europe, and by the mid-18th century cultivars were described that can still be found in gardens.

The muskrat (Ondatra zibethicus) is a medium-sized semiaquatic rodent native to North America and an introduced species in parts of Europe, Asia, and South America. The muskrat is found in wetlands over a wide range of climates and habitats. It has important effects on the ecology of wetlands, and is a resource of food and fur for humans.
Adult muskrats weigh 0.6–2 kg (1.3–4.4 lb), with a body length of 20–35 cm (8–10 in). They are covered with short, thick fur of medium to dark brown color. Their long tails, covered with scales rather than hair, are their main means of propulsion. Muskrats spend most of their time in the water, and can swim under water for 12 to 17 minutes. They live in families, consisting of a male and female pair and their young. To protect themselves from the cold and from predators, they build nests that are often burrowed into the bank with an underwater entrance. Muskrats feed mostly on cattail and other aquatic vegetation, but also eat small animals.

The Dead Sea (Hebrew: יָם הַמֶּלַח‎ Yam ha-Melah lit. Sea of Salt; Arabic: البحر الميت‎ Al-Bahr al-Mayyit or Buhayrat, Bahret or Birket Lut, lit. "Lake/Sea of Lot") is a salt lake bordered by Jordan to the east and Israel and the West Bank to the west. It lies in the Jordan Rift Valley, and its main tributary is the Jordan River.
The lake's surface is 430.5 metres (1,412 ft) below sea level, making its shores the lowest land-based elevation on Earth. It is 304 m (997 ft) deep, the deepest hypersaline lake in the world. With a salinity of 342 g/kg, or 34.2% (in 2011), it is one of the world's saltiest bodies of water – 9.6 times as salty as the ocean – and has a density of 1.24 kg/litre, which makes swimming similar to floating. This salinity makes for a harsh environment in which plants and animals cannot flourish, hence its name. The Dead Sea's main, northern basin is 50 kilometres (31 mi) long and 15 kilometres (9 mi) wide at its widest point.The Dead Sea has attracted visitors from around the Mediterranean Basin for thousands of years. It was one of the world's first health resorts (for Herod the Great), and it has been the supplier of a wide variety of products, from asphalt for Egyptian mummification to potash for fertilisers.

Smoking is a practice in which a substance is burned and the resulting smoke is breathed in to be tasted and absorbed into the bloodstream.  Most commonly, the substance used is the dried leaves of the tobacco plant, which have been rolled into a small rectangle of rolling paper to create a small, round cylinder called a "cigarette".  Smoking is primarily practised as a route of administration for recreational drug use because the combustion of the dried plant leaves vaporizes and delivers active substances into the lungs where they are rapidly absorbed into the bloodstream and reach bodily tissue.  In the case of cigarette smoking these substances are contained in a mixture of aerosol particles and gases and include the pharmacologically active alkaloid nicotine; the vaporization creates heated aerosol and gas into a form that allows inhalation and deep penetration into the lungs where absorption into the bloodstream of the active substances occurs.  In some cultures, smoking is also carried out as a part of various rituals, where participants use it to help induce trance-like states that, they believe, can lead them to spiritual enlightenment.
Smoking is one of the most common forms of recreational drug use. Tobacco smoking is the most popular form, being practised by over one billion people globally, of whom the majority are in the developing countries. Less common drugs for smoking include cannabis and opium. Some of the substances are classified as hard narcotics, like heroin, but the use of these is very limited as they are usually not commercially available. Cigarettes are primarily industrially manufactured but also can be hand-rolled from loose tobacco and rolling paper.

Brazil (Portuguese: Brasil; Brazilian Portuguese: [bɾaˈziw]), officially the Federative Republic of Brazil, is the largest country in both South America and Latin America. It covers an area of 8,515,767 square kilometres (3,287,956 sq mi), with a population of over 211 million. Brazil is the world's fifth-largest and sixth-most populous country, composed of 26 states and the Federal District. It is the largest country to have Portuguese as an official language and the only one in the Americas. Brazil is one of the world's most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world. It is also the most populous Roman Catholic-majority country, and its capital is Brasília, while the largest city is São Paulo.
Brazil is bounded by the Atlantic Ocean to the east, and has a coastline of 7,491 kilometers (4,655 mi). It covers roughly half of South America's landmass, and borders all other countries in the continent except Ecuador and Chile. Its Amazon basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage makes Brazil one of the seventeen megadiverse countries, and is the subject of significant global interest, as environmental degradation through processes like deforestation has direct impacts on global issues like climate change and biodiversity loss.

A seahorse (also written sea-horse and sea horse) is any of 46 species of small marine fish in the genus Hippocampus. "Hippocampus" comes from the Ancient Greek hippokampos (ἱππόκαμπος hippókampos), itself from  hippos (ἵππος híppos) meaning "horse" and kampos (κάμπος kámpos) meaning "sea monster". Having a head and neck suggestive of a horse, seahorses also feature segmented bony armour, an upright posture and a curled prehensile tail. Along with the pipefishes and seadragons (Phycodurus and Phyllopteryx) they form the family Syngnathidae.


== Habitat ==
Seahorses are mainly found in shallow tropical and temperate salt water throughout the world, from about 45°S to 45°N. They live in sheltered areas such as seagrass beds, estuaries, coral reefs, and mangroves. Four species are found in Pacific waters from North America to South America. In the Atlantic, Hippocampus erectus ranges from Nova Scotia to Uruguay. H. zosterae, known as the dwarf seahorse, is found in the Bahamas.
Colonies have been found in European waters such as the Thames Estuary.Three species live in the Mediterranean Sea: H. guttulatus (the long-snouted seahorse), H. hippocampus (the short-snouted seahorse), and H. fuscus (the sea pony). These species form territories; males stay within 1 m2 (10 sq ft) of habitat, while females range over about one hundred times that.
