Задание 2. Прочитайте текст о Мальтийских островах. Определите, какие из приведённых утверждений соответствуют содержанию текста (1 – True), какие не соответствуют (2 – False) и о чём в тексте не сказано, то есть на основании текста нельзя дать ни положительного, ни отрицательного ответа (3 – Not stated). Отметьте правильное утверждение.The Maltese Islands are a group of little islands in the Mediterranean Sea. The population of Malta is about 400,000 people. In spite of being so small in size, Malta is quite a famous place and lots of tourists visit it every year.
Tourists in Malta have many kinds of entertainment to choose from. Clear and warm water is full of marine life and attracts divers and people who enjoy swimming and sailing. The place is also unique for people who are interested in history and architecture as there are lots of historical buildings, temples and cathedrals there. There’s the evidence that the first settlers appeared in Malta about 7,000 years ago, so this is one the oldest places on the Earth inhabited by people.
The Maltese are proud of their unique history. They survived through the Arabs and Roman occupation, and they remember the knights of Malta, Napoleon and Nelson. They do their best to keep their history and traditions and are always glad to share it with tourists. Band clubs are part of the social and cultural history of the Maltese Islands. They see their aim in spreading the culture and teaching of music. The idea of forming some music societies or band clubs appeared in the second part of the 19th century. Small bands were formed in little villages. Anyone could join them. As most participants could not afford to buy a musical instrument of their own, well–to–do villagers helped to pay for the instruments on the condition that the musicians would perform at their village feasts. Today, according to the latest survey by the statistics office, the total number of bandsmen/women is over 4000. Many well–known musicians started their career in a local band club and performed at their village feasts.
