Câu hỏi: Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct word or phrase that best fits each of the numbered blanks from 26 to 30.
Human beings have a superpower - sweating. When temperatures rise, bends of sweat exude from our pores and evaporate, releasing energy that cools the skin and keeps our bodies (26) ___________ overheating. This self-cooling mechanism has helped humans spread to (27) ___________ hot and humid corner of the globe. But that sweating superpower has a theoretical upper limit: When it gets too hot and humid, the laws of physics inhibit sweat from cooling skin. That limit is hit when a bulb thermometer wrapped in a wet towel (a measure of heat and humidity (28) ___________ is known as "wet-bulb" temperature) reads 35° Celsius, or 950 Fahrenheit. Even the fittest human supplied with unlimited water would probably die after a few hours in these conditions.
Scientists have thought that this temperature extreme occurs rarely, if ever, on Earth (29) ___________globe warms, wet-bulb temperatures around 35°C could become more common toward the end of the century in certain regions, endangering hundreds of millions of people.
If carbon emissions aren't (30) ___________curbed in the coming decades, these relatively rare extremes will become increasingly common. Such conditions are unbearable without technology like air conditioning and make outdoor labor near impossible.
