Bad people, called hooligans, do very naughty things like fighting, scaring others, and breaking stuff. Sometimes they do this at sports games. A long time ago, people started to use the word "hooligan". Some people think it came from a song about a loud Irish family. Others say it was an Irish man's name who did bad things in London. A funny story says it's from a word for small bugs that annoyed a big English soldier.
The first time people wrote "hooligan" was in 1894 about a group of young troublemakers. They lived in London and one of them did something very bad – they hurt someone. Newspapers started to use the word a lot after that. A man who worked at a court said that these troublemakers didn't like to work and took money from people by scaring them. This was happening in many places, not just in one area.
Sport is a fun thing you can do. It makes you strong and good at moving. People who play sports follow rules to make it fair. They try to win, and sometimes they can tie. You can play alone or with others in a group.
Some sports need you to move a lot. There are big contests for these sports. But some games do not need a lot of moving, like chess. A big group, the Olympic Games, says chess is a sport.
People keep track of who wins in sports. This is good because many people like to know about sports.
In cricket, there is a special way to help umpires make good choices. It is called the DRS. It uses videos, a machine to see where the ball goes, microphones to hear sounds, and cameras that see heat to check if the ball hits the bat.
A man named Tony Verna made instant replay in 1963. It changed sports.
In cricket, since 1992, umpires on the field could ask a third umpire for help. In 2008, players got to ask too. The first time for this in a big cricket game was in 2008. The first time in a one-day game was in 2011. It was first used in a short game in 2017.
Other sports like soccer and tennis also use this system. The official start of using DRS in cricket was in 2009 in a game between two countries, New Zealand and Pakistan. It is sometimes used in cricket games.
