Read the following passage and mark the letter A, B, C or D on your answer sheet to indicate the correct answer to each of the questions
Plants and animals will find it difficult to escape from or adjust to the effects of global warming. Scientists have already observed shifts in the lifecycles of many plants and animals, such as flowers blooming earlier and birds hatching earlier in the spring. Many species have begun shifting where they live or their annual migration patterns due to warmer temperatures.
With further warming, animals will tend to migrate toward the poles and up mountainsides toward higher elevations. Plants will also attempt to shift their ranges, seeking new areas as old habitats grow too warm. In many places, however, human development will prevent these shifts. Species that find cities or farmland blocking their way north or south may become extinct. Species living in unique ecosystems, such as those found in polar and mountaintop regions, are especially at risk because migration to new habitats is not possible. For example, polar bears and marine mammals in the Arctic are already threatened by dwindling sea ice but have nowhere farther north to go.
Projecting species extinction due to global warming is extremely difficult. Some scientists have estimated that 20 to 50 percent of species could be committed to extinction with 2 to 3 Celsius degrees of further warming. The rate of warming, not just the magnitude, is extremely important for plants and animals. Some species and even entire ecosystems, such as certain types of forest, may not be able to adjust quickly enough and may disappear. Ocean ecosystems, especially fragile ones like coral reefs, will also be affected by global warming. Warmer ocean temperatures can cause coral to “bleach”, a state which if prolonged will lead to the death of the coral. Scientists estimate that even 1 Celsius degree of additional warming could lead to widespread bleaching and death of coral reefs around the world. Also, increasing carbon dioxide in the atmosphere enters the ocean and increases the acidity of ocean waters. This acidification further stresses ocean ecosystems.

A.they may be endangered
B.they can begin to develop
C.they will certainly need water
D.they move to tropical forests

    A rainbow is an optical display of color that usually appears in the sky when a beam of sunlight refracts through millions of raindrops. Each (31)________ color from the spectrum is then sent to your eyes. For this to happen, the angle between the ray of light, the raindrop and the human eye must be between 40 and 42 degrees.
   After studying rainbows in (32)________, Sir Isaac Newton was able to explain how they are formed. However, he was color blind, so he had to rely on the eyes of his assistant, who could easily (33)________all the seven colors: red, orange, yellow, green, blue, indigo and violet. His assistant could also clearly tell the difference between indigo and violet.
   There are two types of rainbows. Primary rainbows are the most common and have the most distinctive colors, with red appearing on the outside of the arc and violet on the inside. Secondary rainbows are unusual because the light is reflected twice within the raindrop before it (34)________ a rainbow, so the colors are in reverse order and not as bright as primary rainbows.
  There is a popular myth that if you reach the end of a rainbow, you will find a pot of gold waiting for you. In fact, it is impossible to do this, because a rainbow has no end - as you go towards the point where the rainbow seems to touch the ground, it moves away from you as quickly as you (35)________.
