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.
What makes it rain? Rain falls from clouds for the same reason anything falls to Earth. The Earth’s gravity pulls it. But every cloud is made of water droplets or ice crystals. Why doesn’t rain or snow fall constantly from all clouds? The droplets or ice crystals in clouds are exceedingly small. The effect of gravity on them is minute. Air currents move and lift droplets so that the net downward displacement is zero, even though the droplets are in constant motion.
Droplets and ice crystals behave somewhat like dust in the air made visible in a shaft of sunlight. To the casual observer, dust seems to act in a totally random fashion moving about chaotically without fixed direction. But in fact dust particles are much larger than water droplets and they finally fall. The cloud droplet of average size is only 1/2500 inch in diameter. It is so small that it would take sixteen hours to fall half a mile in perfectly still air, and it does not fall out of moving air at all. Only when the droplet grows to a diameter of 1/125 inch or larger can it fall from the cloud. The average raindrop contains a million times as much water as a tiny cloud droplet. The growth of a cloud droplet to a size large enough to fall out is the cause of rain and other forms of precipitation. This important growth process is called “coalescence”.
Why don’t all ice crystals in clouds immediately fall to the Earth?

A. They are balanced by the pressure of rain droplets.

B. The effect of gravity at high altitude is random.

C. They are kept aloft by air currents.

D. The heat from the Sun’s rays melts them.

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.
Edward Patrick Francis “Eddie” Eagan (April 26, 1897-June 14, 1967), was an amateur boxing star of the early 1920s. He was born into a poor family in Denver, Colorado. His father died in a railroad accident when Eagan was only a year old. He and his four brothers were raised by his mother, who earned a small income from teaching foreign languages.
Inspired by Frank Merriwell, the hero of a series of popular novels for boys, Eagan pursued an education for himself as well as an interest in boxing. He attended the University of Denver for a year before serving in the U.S. Army as an artillery lieutenant during World War I. After the war, he entered Yale University and, while studying there, won the U.S. national amateur heavyweight boxing title. He graduated from Yale in 1921, attended Harvard Law School, and received a Rhodes scholarship to the University of Oxford where he received his Master’s Degree in 1928.
While studying at Oxford, Eagan became the first American to win the British amateur boxing championship. Eagan won his first Olympic gold medal as a light heavyweight boxer at the 1920 Olympic Games in Antwerp, Belgium. Eagan also fought at the 1924 Olympics in Paris as a heavyweight but failed to get a medal. Though he had taken up the sport just three weeks before the competition, he managed to win a second gold medal as a member of the four-man bobsled team at the 1932 Olympics in Lake Placid, New York. Thus he became the only athlete to win gold medals at both the Summer and Winter Olympics.
Eagan was a member of the first group of athletes inducted into the U.S. Olympic Hall of Fame in 1983. Eagan became a respected attorney, serving as an assistant district attorney for southern New York and as chairman of the New York State Athletic Commission (1945-51). He married soap heiress. Margaret Colgate and attained the rank of lieutenant colonel during World War II. He died at the age of 70, in Rye, New York.
