SECTION A: 8 points

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

A pilot cannot fly by sight alone In many conditions, such as flying at night and landing in dense fog, a pilot must use radar, an alternative way of navigating Since human eyes are not very good at determining speeds of approaching objects, radar can show a pilot how fast nearby planes are moving The

basic principle of radar is exemplified by what happens when one shouts in a cave The echo of the sounds

against the walls helps a person determine the size of the cave With radar, however, the waves are radio waves instead of sound waves Radio waves travel at the speed of light, about 300,000 kilometres in one second A radar set sends out a short burst of radio waves Then it receives the echoes produced when the waves bounce off objects By determining the tune it takes for the echoes to return to the radar set, a trained technician can determine the distance between the radar set and other objects The word “radar” in fact gets

its name from the term “radio detection and ranging” “Ranging” is the term for detection of the distance between an object and the radar set Besides being of critical importance to pilots radar is essential for air traffic control tracking ships at sea, and for tracking weather systems and storms

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

One of the major problems in the art world is how to distinguish and promote an artist In effect, a

market must be created for an artist to become successful The practice of signing and numbering individual prints was introduced by James Abbott McNeill Whistler, the nineteenth-century artist best known for the painting of his mother, called “Arrangement in Grey and Black,” but known to most of us as “Whistler’s

Mother.” Whistler’s brother-in-law, Sir Francis Seymour Haden, a less well-known artist, had speculated

that collectors might find prints more attractive if they knew that there were only a limited number of copies produced By signing the work in pencil, an artist could guarantee and personalize each print

As soon as Whistler and Haden began the practice of signing and numbering their prints, their work began to increase in value When other artists noticed that the signed prints commanded higher prices, they began copying the procedure

Although most prints are signed on the right-hand side in the margin below the image, the placement of the signature is a matter of personal choice Indeed, prints have been signed within the image, in any of the

margins, or even on the reverse side of the print Whenever the artist elects to sign it, a signed print is still

valued above an unsigned one, even in the same edition
