$x^2-4\ \textgreater \ 0 \\ x^2-2^2\ \textgreater \ 0 \\ (x-2)(x+2)\ \textgreater \ 0$ нули: $x=2 \\ x=-2$ методом интервалов: $x\in (-\infty;-2) \cup (2;+\infty)$

Помогите, очень прошу !!!:<<<<< Помогите только с вопросами((
Cinema is much younger than theatre. It was born at the end of the 19th century. The first people who showed the first movies to the public were the Lumier Brothers of France. They did it at the Grand Cafe, Boulevard des Capucines, Paris, on the 20th February 1896. This was the first cinema show. Very quickly cinema appeared in many other places in all parts of the world.
The first films showed moving people and transport, then people were able to see short comedies on the screen. In 1901 France was the first country to produced a dramatic film, The Story of a Crime, then The Great Train Robbery appeared in the United States in 1903.
At first, people could see films anywhere: in music halls, clubs and shops. By 1908 special film theatres began to give regular programmes. At this time cinema rapidly developed in both the New and the Old World. Charlie Chaplin made his first film, Making a Living, in 1914 in the USA. The Russian film industry was now going on its own way. It produced such great films as Protazanov's The Queen of Spades (1916) and Father Sergius (1918). A little later The Battleship "Potemkin" came to the screen. Than was Russia's great achievement in cinema. The film director was Sergey Eisenstein. In 1927, Warner Brothers in Hollywood made the first film in which an actor sang and spoke. The film's title was Jazz Singer. It had three songs and a short dialogue. That opened a new era in films- the era of the "talkies", or sound films. The silent film was dead within a year. The first one hundred percent sound film, Lights of New York, appeared in 1928, and the first colour films - in the 1930s.
1) When was cinema born?
2) What country prodused the first dramatic film?
3) Why is the film Jazz Singer important in the history of cinema?
4) Where could the people watch the first films?
5) What can you say about the first Russian films?
6) When was the era of silent films over? When did the era of talkies, or sound films began?
7) When did the first colour films appear?
