The Mediterranean island of Malta is home to a puzzling archaeological site that consists of a collection of pairs of parallel lines, or grooves, carved into the rock of the ground. These grooves, thought to be at least a few thousand years old, can be quite long, and they seem to connect various locations on the island. There are several theories that attempt to explain the origin of the grooves.
One theory suggests that the grooves were carved as irrigation channels to carry water. Ancient societies, like those on Malta, depended heavily on agriculture, and agriculture requires having enough water for crops to grow. The grooves are large enough to carry a significant volume of water, and given that Malta has limited freshwater resources, it may be that the grooves served the purpose of irrigation.
Another view is that the grooves were made by wheeled vehicles, such as carts used to transport objects. If carts traveled over the same path repeatedly, their wheels could have created noticeable grooves in the rock. Similar-looking tracks have been found at other locations around the world, but the Maltese grooves stand out because they are much deeper. This may be because the rock in Malta consists mostly of soft limestone, which can easily be worn away, especially when wet. Given the softness of the Maltese limestone, it is possible that carts left the deep grooves.
Finally, the Maltese grooves may have been created to serve some astronomical purpose. Many ancient cultures closely studied the planets and stars, and some of those cultures carved marks or grooves into rock that appear to have been used to make astronomical observations. Some ancient stone grooves found elsewhere in Europe have been shown to have connections to the movements of the Sun and planets. So the Maltese grooves may also have been made by ancient astronomers who used them to predict the locations of the Sun and planets.
The reading passage states some theoretical concepts to explain the origin of the grooves found in Malta. However, the professor in the listening states, why the assumptions mentioned in the reading passage are incorrect and refutes tham by describing three reasons as follows.
Firstly, the reading posits that grooves may have been carved for irrigational purposes. Since Malta endows with limited fresh water resources, useing grooves as irrigation channels seems logical. The professor casts doubt on this point by mentioning that usually irrigation channels are built downward from the lakes or streams but, grooves in Malta are carved both in downhill and uphill ways. Therefore, water can't get far in some routes because of the force of gravity.
Secondly, the reading cliams that since the limstone in Malta is soft, the grooves can be the result of the wheeled vehicles' marks. In contrast, the professor says that this assumption is not complete because the vehicles were being used by people or animmals in those days, accordingly, there should be some marks of animal or human footprint on the ground.
Finally, the reading says that the grooves were carved for some astronomical purposes like the other grooves found in various parts of Europe. The professor opposes this point by explaining that all other grooves that have been carved to illustrate astronomical incidents in Europe are carved in stright directions. However, the grooves in Malta change direction continuously, and they can not be allocated for a specific astronomical reason.
