Read the text and decide if the sentences are T (true) or F (false)

If you look at the map of Scotland you will find that there are many lakes in the country. The Scots called them “locks”. And the most famous of them is Loch Ness. According to the scientists it is 25,000 years old.
Loch Ness is a mysterious lake. For many years there have been reports of an unusual and great creature. People tell many stories about a water monster which lives in the lake. They call it Nessie. People, who said they had seen Nessie, describes it as a strange creature which had a giraffe-like neck, a very small head and a great dark grey body.
The stories of this mysterious creature, called the “Loch Ness Monster” have filled the people with excitement and curiosity. Many visitors and newspaper reporters have tried to photograph the monster. Not only newspaper reporters and curious visitors take a great interest in the Loch Ness Monster. Scientists do not like mysteries, they want facts. Expeditions of British, American and Canadian scientists took more than 100,000 underwater photographs in Loch Ness, but they didn’t help find out whether the monster really exists.
A lot is said and written about the monster. There even exists the Nessie Museum. For some people Nessie is good business: T-shirts with “Nessie” on them, books about the monster and all kinds of picture postcards and souvenirs are sold to thousands of visitors every year.
