Read the following passage and blacken the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions.

There is a common expression in the English language referring to a blue moon. When people say that something happens “only once in a blue moon,” they mean that it happens only very rarely, once in a great while. This expression has been around for at least a century and a half; there are references to this expression that date from the second half of the nineteenth century. (5) The expression “a blue moon” has come to refer to the second full moon occurring in any given calendar month. A second full moon is not called a blue moon because it is particularly blue or is any different in hue from the first full moon of the month. Instead, it is called a blue moon because it is so rare. The moon needs a little more than 29 days to complete the cycle from full moon to full moon. Because every month except February has more than 29 days, every month will have at least one full moon (except February, which will have a full moon unless there is a full moon at the very end of January and another full moon at the very beginning of March). It is on the occasion when a given calendar month has a second full moon that a blue moon occurs. This does not happen very often, only three or four times in a decade. The blue moons of today are called blue moons because of their rarity and not because of their color; however, the expression “blue moon” may have come into existence in reference to unusual circumstances in which the moon actually appeared blue. Certain natural phenomena of gigantic proportions can actually change the appearance of the moon from Earth. The eruption of the Krakatao volcano in 1883 left dust particles in the atmosphere, which clouded the sun and gave the moon a bluish tint. This particular occurrence of the blue moon may have given rise to the expression that we use today. Another example occurred more than a century later. When Mount Pinatubo erupted in the Philippines in 1991, the moon again took on a blue tint.

Which of the following might be the date of a “blue moon”?

A. January 1

B. February 28

C. April 15

D. December 31

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 from 33 to 38.

Sylvia Earle, a marine botanist and one of the foremost deep-sea explorers, has spent over 6,000 hours, more than seven months, underwater. From her earliest years, Earle had an affinity for marine life, and she took her first plunge into the open sea as a teenager. In the years since then she has taken part in a number of landmark underwater projects, from exploratory expeditions around the world to her celebrated “Jim dive” in 1978, which was the deepest solo dive ever made without cable connecting the diver to a support vessel at the surface of the sea.

Clothed in a Jim suit, a futuristic suit of plastic and metal armor, which was secured to a manned submarine, Sylvia Earle plunged vertically into the Pacific Ocean, at times at the speed of 100 feet per minute. On reaching the ocean floor, she was released from the submarine and from that point her only connection to the sub was an 18-foot tether. For the next 2½ hours, Earle roamed the seabed taking notes, collecting 15 specimens, and planting a U.S. flag. Consumed by a desire to descend deeper still, in 1981 she became involved in the design and manufacture of 20 deep-sea submersibles, one of which took her to a depth of 3,000 feet. This did not end Sylvia Earle’s accomplishments.

The main purpose of this passage is _______. 

A. to explore the botany of ocean floor 

B. to present a short biography of Sylvia Earle 

C. to provide an introduction to oceanography 

D. to show the historical importance of the Jim dive
