The sentence that is essential to a summary of paragraph 2 is:
Directions: Read the following passage and then answer questions 1–10. A poison is any substance that can harm the body, sometimes seriously enough to create a medical emergency. In the United States, there are more than a million reported cases of poisoning annually. Although some of these result from murder or suicide attempts, most are accidental and involve young children. These incidents usually involve 1 common substances such as medications, petroleum products, cosmetics, and pesticides. In fact, a surprisingly large percentage of chemicals in everyday use contain substances that are poisonous if misused. We usually think of a poison as some kind of liquid or solid chemical that has been ingested by the poisoning victim. Although this is often the case, many living organisms are capable of producing a toxin, a substance that is poisonous to humans. For example, 2 some mushrooms and other common plants can be poisonous if eaten. These include some varieties of house plants, including the rubber plant and certain parts of holiday plants such as mistletoe and holly berries. In addition, bacterial contaminants in food may produce toxins, some of which can cause deadly diseases (such as botulism). A great number of substances can be considered poisonous, with different people eacting differently to various poisons. As odd as it may seem, what may be a dangerous 3 poison for one person may have little effect on another. For most poisonous substances, the reaction is far more serious in the ill, the very young, and the elderly. Poisons can be classified into four types, according to how they enter the body: • Ingested poisons (poisons that are swallowed) can include many common household 4 and industrial chemicals, medications, improperly prepared or stored foods, plant materials, and agricultural products made specially to control weeds, pests, and crop diseases. • Inhaled poisons (poisons that are breathed in) take the form of gases, vapors, and sprays. Again, many of these substances are in common use in the home, industry, and agriculture. Such poisons include carbon monoxide (from car exhaust, wood- burning stoves, and furnaces), ammonia, chlorine, insect sprays, and the gases produced from volatile liquid chemicals. • Absorbed poisons (poisons taken into the body through unbroken skin) may or may not damage the skin. Many are corrosives or irritants that will injure the skin and then be slowly absorbed into body tissues and the bloodstream; others are absorbed into the bloodstream without injuring the skin. Examples of these poisons include insecticides, agricultural chemicals, plant materials, and certain forms of marine life. • Injected poisons (poisons inserted through the skin) enter the body through a means that penetrates the skin. The most common injected poisons include illicit drugs injected with a needle and venoms injected by snake fangs or insect stingers. a. We usually think of a poison as something ingested by the poisoning victim. b. Many living organisms can produce a toxin, a substance that is poisonous to humans. c. Some mushrooms and other common plants can be poisonous if eaten. d. Poisonous house plants include the rubber plant, mistletoe, and holly berries.

En los países hispanos, el mercado es un evento esencial en la vida tanto para comprar como para interactuar con otros habitantes del pueblo o la ciudad. Los mercados sirven como un lugar donde la gente puede comprar y vender diferentes productos, como alimentos locales, muebles y otras cosas para la casa. Los mercados son tradicionales y a veces tienen productos que no puedes encontrar en el supermercado. Sin embargo, el supermercado ofrece una variedad más grande de productos que un mercado al aire libre. Ir al mercado es un evento semanal para muchas personas, porque así pueden ver a amigos y familiares que viven más lejos. Además, es cuando pueden conseguir mucho de lo que necesitan y que no pueden comprar en las tiendas cerca de sus casas. Los platos típicos de cada región reflejan los ingredientes comunes que se usan. Por ejemplo, en Puerto Rico la carne de cerdo es muy popular. El lechón asado es un plato muy típico que consiste en un cerdo entero asado sobre un fuego lento durante muchas horas afuera en el patio. Se le añade a la carne la sal, la pimienta y el orégano para darle más sabor. Los puertorriqueños lo comen especialmente en la Navidad o en una celebración familiar. Otro plato típico, esta vez de postre, tanto en el Caribe como en otros países hispanos es el flan. Los ingredientes principales de un flan incluyen los huevos, la leche, la leche condensada, la vainilla y el azúcar. Muchas veces, el flan puede llevar otros sabores especiales como el coco. Para el flan de coco se requiere el agua de coco. El flan es un postre que la gente come frío, no caliente, y es muy rico. ¿Cuál no es un ingrediente típico de un flan? a. sal b. huevo c. azúcar d. leche
