In antiquity, prior to the third century B.C., physics had been a branch of philosophy. It was made a separate, experimental science by Archimedes of Syracuse, who lived between 287 and 212 B.C.. He not only discovered the law of floating objects, or specific gravity, but also formulated with scientific exactness the principles of the lever, the pulley, and the screw. Among his memorable inventions were the compound pulley and the screw propeller for ships. Although he has been considered the greatest technical genius of antiquity, in fact he preferred to devote himself to pure scientific research. Tradition relates that he discovered "Archimedes' principle," that is, specific gravity, while pondering possible theories in his bath; when he reached his stunning insight, he dashed out naked into the street crying "Eureka!" ("I have found it!").
76. As one understands from the passage,
Archimedes was so thrilled by his unexpected discovery of specific gravity that —.
A) he immediately announced it to the public in an unusual fashion
B) he described every detail of it to the people with scientific exactness
C) the people in the street joined him in the celebration of his discovery
D) most of his contemporaries regarded it as a perfect example of pure scientific research
E) his theory of specific gravity was soon applied in shipbuilding
77. According to the passage, until Archimedes, —.
A) there had been some scientific research on the law of floating objects
B) physics had not been considered to be a science separate from philosophy
C) the use in ships of the screw propeller had already been known
D) various theories had been proposed about floating objects
E) the study of philosophy had been confined only to physics
78. As it is clear from the passage, Archimedes -—.
A) was so seriously concerned with technical issues that he often neglected his scientific research
B) can be described as a man who openly opposed the study of philosophy
C) was more interested in the theoretical aspect of science than in its practical uses
D) was particularly indifferent to questions of navigation and shipbuilding
E) taught the people of Syracuse how to use the compound pulley most efficiently
79. It is pointed out in the passage that Archimedes' inventions —.
A) were not related to the theories that he had
already formulated
B) have qualified him to be regarded as "the greatest genius of antiquity"
C) were put into use when, following several scientific tests, they proved to be very efficient
D) were all based on his theory of specific gravity, which he had been pondering for a long time
E) were described in detail in his writings
80. As clearly pointed out in the passage, like the principles of the pulley and the screw, the principle of the lever —.
A) has been traditionally attributed to Archimedes, but it had been known to other physicists in antiquity
B) can also be considered to be one of Archimedes' least scientific formulations
C) aroused so much interest in the public that he was rightly proud of his scientific discovery
D) was also defined by Archimedes in absolutely scientific terms
E) was formulated by Archimedes only after he carried out a series of complicated experiments

Why do ships float on water when in fact they should sink? Why does paper float on water? Why does a paperweight sink? The answer to these questions was accidentally discovered 2200 years ago by the Greek inventor and mathematician, Archimedes. One day, while getting into his bath he noticed water spilling over the sides. In a flash, Archimedes realised the relation between the water that had fallen out and the weight of his body - in other words he discovered why some objects float and some sink! Archimedes was so excited with his discovery that he hopped out of the bath, and rushed naked into the street yelling triumphantly, 'Eureka!' 'Eureka!' (Greek word for 'I have found it!).
1) One can understand from the passage that the mystery related to floating of the paper in the water _____________________.
A) came into light more than two millennia before
B) is still occupying the scientists' mind in many aspects
C) could only be explained with some experiments
D) has thoroughly changed the approaches the explorers had to science
E) is the main reason why some inventors lost their lives by getting drowned
2) As seen from the example of Archimedes in the passage, _____________________.
A) all the inventors have found something by coincidence
B) the patents of some finds haven't found their owners, yet
C) the feeling of thrill might lead to uncontrollable actions
D) water's power to pick up does not bear any relation to other finds
E) many scientists were born to a very poor family
3) After reading the whole passage, one can come to the conclusion that _____________________.
A) in the past, people avoided having a bath in the bath-tub
B) Archimedes was a great mathematician but had problems with his mood
C) there were many inventors with basic health problems in Archimedes' time
D) the reason why some questions weren't solved was because of the lack of miracles
E) the various questions are all based on the same principle
