Task 1. Read the text and answer the questions
There is a legendary monster that people say lives in the deep Loch Ness
Lake in the north of Scotland. It is called the Loch Ness Monster or
for short. It looks kind of like a dinosaur, with a small head on a long neck
and humps on its back. People first spotted Nessie in 1933. Since then,
there have been many sightings and a few photographs. Now, scientists
from New Zealand will use a special technique to see if there really is a
Loch Ness Monster. A research team, led by Professor Neil Gemmell of the
University of Otago, will use a technique called eDNA sampling to try and
find some of Nessie’s DNA. Professor Gemmell says this will show if the
monster really exists or not.
Sightings of the Loch Ness Monster are often in the newspapers.
Loch Ness is in the Scottish Highlands. The word h» is the Scots word
for «lake». Many scientists have tried to find the monster before. They have
even sent sonar equipment to the bottom of the loch, which is 230 metres
deep. All of the photographs that people have taken of Nessie over the
years are blurred. Some people say they are just car tires floating in the
water. Gemmell says he will test water from the loch. He said there should
be DNA from the monster’s skin, urine and other things. He will check all
DNA found and make sure it is not from other marine animals. If he finds
DNA not known to scientists, that could belong to Nessie.

Задание номер 8 — задание базового уровня сложности, выполнение которого предполагает знание о методах измерения количества информации и не требует использования специального ПО. Зачастую в номере 8 мы можем встретить задания связанные с комбинаторикой — перестановками, количеством вариантов выборки и т.д. Для решения заданий такого типа можно приспособить модуль itertools языка python. Сразу оговорюсь, что
