The passage mainly puts forward three theories to explain the purpose and meaning of the carved stone balls. Nevertheless, the professor in the lecture argues that none of the theories are convincing enough to identify what the carved stoneballs are made for.

Regarding on the first theory, carved stone balls being weapons used in hunting or fighting, the lecturer argues that if the stone balls were used as weapons for hunting or fighting like arrowheads and hand axes, both of which were common Neolithic weapons, they would show signs of wear or damage since they would be cracked or have pieces broken off in the fighting, but the surfaces of the balls are well preserved and show little signs of wear and damage. As a result, the stone ball cannot be used as weapons as the reading suggests.

Secondly, the passage holds the hypothesis that carved stone balls were used as part of a primitive system of weights and measures because they are uniform in size. According to the lecturer, however, the carved stone balls are uniform in size but this cannot prove that they were used as a primitive weighing system. This is because the stones balls were made of stones of different density, such as sandstone and green stone, which means that even though two balls are of the same size, they can still be different in weights. Consequently, it is impossible that the carved stones

ARCH VERSION:

There is an argument of reading passage stating that some theories may be able to explain the reason of unknown sounds made around the Russian submarines underwater when patrolling between 1960 and 1989.However, the lecture totally disagrees with these three opinions.

To begin with, the noises were unlikely from the whales since the submarines were in very deep of water. Although the population of whales was rather huge around the submarine's area, the whales indeed were pretty far from the submarines. In addition, it is also impossible that submarines were not detecting such solid objects as large as whales.

Second, the sounds should not come from the giant squids which live deep in the sea either. The listening material claims that the sound only appeared in twenty years (from 1960s to 1980s), while the giant squids were impossible just to live for only that period. Instead, giant squid has always been lived there for long while the sound disappeared after 1980s.

　　A huge marine mammal known as Steller’s sea cow once lived in the waters around Bering Island off the coast of Siberia. It was described in 1741 by Georg W. Steller, a naturalist who was among the first European to see one. In 1768 the animal became extinct. The reasons for the extinction are not clear. Here are three theories about the main cause of the extinction.

　　First, the sea cows may have been overhunted by groups of native Siberian people. If this theory is correct, then the sea cow population would have originally been quite large, but hundreds of years off too much hunting by the native people diminished the number of sea cows. Sea cows were a good source of food in a harsh environment, so overhunting by native people could have been the main cause of extinction.

A little over 2200 years ago, the Roman navy attacked the Greek port city of Syracuse. According to some ancient historians, the Greeks defended themselves with an ingenious weapon called a “burning mirror’, a polished copper surface curved to focus the Sun’s rays onto Roman ships, causing them to catch fire. However, we have several reasons to suspect that the story of the burning mirror is just a myth and the Greeks of Syracuse never really built such a device.

First, the ancient Greeks were not technologically advanced enough to make such a device. A mirror that would focus sunlight with sufficient intensity to set ships on fire would have to be several meters wide. Moreover, the mirror would have to have a very precise parabolic curvature

(a curvature derived from a geometric shape known as the parabola). The technology for manufacturing a large sheet of copper with such specifications did not exist in the ancient world.

Rembrandt is the most famous of the seventeenth-century Dutch painters. However, there are doubts whether some paintings attributed to Rembrandt were actually painted by him. One such painting is known as attributed to Rembrandt because of its style, and indeed the representation of the woman’s face is very much like that of portraits known to be by Rembrandt. But there are problems with the painting that suggest it could not be a work by Rembrandt.

First, there is something inconsistent about the way the woman in the portrait is dressed. She is wearing a white linen cap of a kind that only servants would wear-yet the coat she is wearing has a luxurious fur collar that no servant could afford. Rembrandt, who was known for his attention to the details of his subjects’ clothing, would not have been guilty of such an inconsistency.

In terms whether the zebra mussel will exert negative influence on North American, the passage and lecture are contradictory to each other. The author believes that zebra mussel might do harm the local species as they arrived while the lecturer holds a different opinion.

First of all, the author makes a point that the history events suggest the zebra mussel's invasion is unstoppable. In the past, human transportation makes it possible for zebra mussel spread around the whole Europe and it is likely to happen again in North American. However, the lecturer demonstrates a different idea that a change made in the "ballast water" will prevent the invasion of zebra mussel from continuing. He says that if we refill the "ballast water" with ocean water, the mussel will no longer survive because the saline water might probably kill them all.
