1. 주어진 글 다음에 이어질 글의 순서로 가장 적절한 것은?

Many fruits, vegetables, and flowering trees depend on pollinators, such as honeybees, for their reproduction.

(A) These include loss of habitat of the pollinators (for example, forests), invasive species of parasites (for example, fire ants that attack honeybee populations), viral infections transmitted from abroad, and large-scale use of pesticides, which kill the pollinators.

(B) Indeed, the fruit industry spends vast sums of money on bee pollinators. There is now a mass decline in the wild populations of many pollinators, including honeybees, and also a replacement of native pollinators by unsuitable invasive species.

(C) The results will be declining crop productivity and rising food costs. There is, as with the other areas of disastrous biodiversity decline, a multitude of interacting factors, probably all of which are contributing to the decline.

① (A) - (C) - (B)	② (B) - (A) - (C)	③ (B) - (C) - (A)

④ (C) - (A) - (B)	⑤ (C) - (B) - (A)

2. 글의 흐름으로 보아, 주어진 문장이 들어가기에 가장 적절한 곳은?

Our brain is a great computing machine, but it also places some obstacles in the way of apprehending reality truthfully.

There is no question that the brain-mind mechanism is one of the most glorious achievements of evolution. (①) Unfortunately, despite its many amazing features, it has also developed several procedures that are less desirable. (②) Every impressive evolutionary adaptation winds up blocking other possibilities: the bat has an exceptionally sensitive sonar but poor eyesight; the shark can't see well either but has a fantastic sense of smell. (③) The first of these is the nervous system itself. (④) The more that is known about how the mind works, the more we realize that the filter through which we experience the world has some peculiar built-in biases. (⑤) If we do not understand how these biases work, thoughts and actions are never truly going to be under conscious control.

A distinctive characteristic of the African elephant is its extremely large ears. Besides their important use in hearing, the ears serve as _______________________, similar to those of the fennec fox, which is a small nocturnal fox found in the Sahara of North Africa and has unusually large ears. They provide a large surface area through which runs an extensive network of blood vessels. When the animal is hot, the blood vessels expand and rise above the skin, so that blood running through them is more exposed to the air. Spreading of the ears and ear-flapping are characteristically seen when elephants stand in the shade on hot days because of high-temperature. The action increases the air currents over the blood vessels so blood is cooled more efficiently, helping reduce the body temperature.

① radiators to prevent overheating

② useful tools for giving directions

③ ways of hearing predators moving around

④ symbols of representing its status in a group

⑤ channels of communicating with other elephants

Minderals are necessary for the body to build tissues or assist in various body functions. Minerals are found in all body tissues. They cannot provide energy by themselves, but in their role as body regulators, they contribute to the production of energy within the body. Minerals are found in water and in natural (unprocessed) foods, together with proteins, fats, and vitamins. Humans obtain minerals by eating plants grown in mineral-rich soil or by eating animals that have eaten such plants. The specific mineral content of food is determined by burning the food and then chemically analyzing the remaining ash. Most minerals in food occur as salts, which are soluble in water. Therefore, the minerals leave the food and remain in the cooking water. Using this cooking liquid improves the flavors as well as the nutrient content of foods to which it is added.
