Answer 1

OFSIDE POSITION
It is not an offence in itself to be in an offside position. A player is in an offside position if:
• he is nearer to his opponents’ goal line than both the ball and the second last opponent
A player is not in an offside position if:
• he is in his own half of the field of play or
• he is level with the second last opponent or
• he is level with the last two opponents
In the definition of offside position, “nearer to his opponents’ goal line” means that any part of his head, body or feet is nearer to his opponents’ goal line than both the ball and the second last opponent. The arms are not included in this definition.

YELLOW AND RED CARDS
Yellow and red cards were first introduced in the game by British referee Ken Aston and its first major use was in the 1970 World Cup:
The cards are shown to the players who have committed a foul. The color of the card depends on the severity of the foul.
A yellow card is shown by the referee to indicate that a player has been officially cautioned.
A red card is shown by the referee to indicate that a player has been officially send-off or expelled from the game, and must leave the field inmediatly and won't be able to play the rest of the game.
The referee can give as many cards as needed, the amount of card given is related to the number of offences (requiring a card) during the game.
During a game a player can receive:
1 red card the player, and the player is expell from the game and no substitute player can come in.
1 yellow card (the player has been officially cautioned)
2 yellows card, which is the maximum allow, and it's equivalent to 1 red card and the player has to leave the match (and that's way the referree after the second yellow shows the red card). And like a direct red card, the player can't play the next game for the team and no substitute player can come in.
But during the tournament the player can receive any number of cards.

Receving a yellow card caution
There are seven different offences that can get you a yellow card:
# Anything that can be deemed as unsporting behaviour
# Dissent by word or action
# Persistent infringement of the laws, for example a series of fouls
# Delaying the restart of play
# Not retreating the full ten yards at a free-kick or corner
# Entering or re-entering the field without the referee's permission
# Deliberately leaving the field without the referee's permission

Receving a instant red card send-off
There are seven offences you can be shown a straight red card for:
# Serious foul play.This includes a tackle that endangers the safety of an opponent.
# Violent conduct such as throwing a punch
# Spitting at an opponent or another person
# A player other than the goalkeeper denies an obvious goalscoring opportunity by handling the ball
# A goalkeeper would be similarly punished if they intentionally handle the ball outside their goal area
# Committing an offence that denies an opponent an obvious goal-scoring opportunity (informally known as a professional foul)
# Using offensive, insulting or abusive language or gestures

Receiving Second Yellow card
If the referee shows a player a second yellow card in the game, the referee will show the second yellow card before holding up the red card, meaning that the player is sent off or expelled from the game.

Suspensions (Red card)
Rule: A red card implies 1 game suspension.
If a player gets a red card, in the final game, he will carry over the punishment to the next international game of his team, when he plays.

Carry on the cautions (Yellow card)
The exact punishments are determined by tournament or competition rules (not by the Laws of the Game). The cautions are accumulate for a certain phase of a the world cup tournament.
Rules:
* A yellow card is carry over, and 2 yellow cards equal a red and a 1 game suspension.
* A yellow card is carry on during the first and second phase of the tournament.
* For the quaterfinals is a clean start for all the players, except for a red card.
* Begining the quaterfinals the yellow cards are carry on, until the end of the tournament. And at the end of the tournament all the yellows cards are reset, except:
* If a player gets a second yellow card, in the final game in which his team participated, he will carry over the punishment to the next international game of his team, when he plays (he has to be in the team roster).
* If a player gets a red card, in the final game in which his team participated, he will carry over the punishment to the next international game of his team, when he plays (he has to be in the team roster).

Answer 2

1) offside is when somebody pass the ball and you are ahead of the last player defending when the ball came out of the one who made the pass (if you touch the ball then it is offside) (check the picture in the sources) you see how the yellow player is behind to the defending players when he is recieving the ball?
2)depends on the cup, this one i think yellow cards will be reset after group rounds
3) you get kicked of this game and lose the next game (and even more dependind on how bad was the fault)
