Article: Fouls in water polo are a mixture of basketball and hockey rules, and they range from minor fouls to "brutality" fouls that cause a permanent ejection from the game. Each foul is detailed, along with the referee's reaction and signal, below:   Ordinary Fouls: Referee blows the whistle once and points in the direction the team is attacking towards. Restart is a free throw from the location of the foul. Two whistles indicate that the offense, not the defense, caused the foul.  Exclusions (Major Fouls): Referee blows the whistle twice quickly, then one long blast. They spin their arms to indicate a player must leave, and the fouling player must swim to the edge of the pool for 20 seconds, and play starts with a free throw.  Penalty Fouls: Referee blows the whistle three times, like above, then raises 5 fingers above his/her head. The fouler leaves the field and play starts with a free shot on the 5-meter line for the fouled team. These are also called minor fouls. Ordinary fouls are not counted or used against players, and the clock does not stop after they are called. They are by far the most common fouls in water polo, and include:  Touching the ball with two hands Touching the bottom of the pool Holding the ball underwater to prevent stealing Impeding, or getting in the way of players who don't have the ball to prevent them from moving. Letting the shot clock expire Throwing a ball outside of the pool. These are also called major fouls and are for more serious and aggressive conduct. Once called, the fouling player must immediately swim to a designated zone in front of their bench, usually the halfway line. After 20 seconds or a goal is scored, whichever is first, they can swim back in and resume play. Exclusions fouls are for:  Pulling, holding, or sinking players without the ball. Splashing water in a player's face Blocking a shot with two arms Kicking or hitting another player violently. Disrespecting the game or referee (swearing, leaving the pool and getting back in, spitting) The foul must be within the 5-meter line, as well as preventing a "probable goal." Any foul, if it takes away a probable goal, can be a penalty foul. Your team gets the ball at the 5-meter line against the goalie, and play resumes after the shot.  Very violent fouls, called "brutality," can result in a penalty shot regardless of where in the pool the foul was committed. Most penalty fouls are called when a defender fouls a shooting player from behind. The goalie must be completely within the goal for the shot, not in front of it. These are for excessive or violent fouls, like kicking, striking, or extreme language or unsportsmanlike conduct. You must leave for the remainder of the game, and your team will play a man down for four minutes.  If a penalty foul is called for a brutality, the team who was fouled gets the ball back at the half line after shooting, even if they scored. A strike that is determined as deliberate is the most common brutality called. If you receive three exclusion calls against you, you are out for the remainder of the game. Unless the final foul was considered a brutality, your team may substitute another player in your place when you leave. Your team still has to play with the 20-second exclusion -- you can substitute after this period is over. Again, this is similar to soccer. If the referee thinks you're better off keeping the ball, such as being fouled right after you make a good pass, they can say "advantage" to acknowledge the foul but keep your team's offensive momentum. In general, overly violent or dangerous fouls are called immediately even if there is an advantage.
Question: What is a summary of what this article is about?
Understand the three categories of fouls and their consequences. Restart ordinary fouls with a free throw at the spot of the foul. Sit players for 20 seconds, with their team playing a man down, for exclusion fouls. Grant penalty shots for fouls within the offensive 5-meter line or very rough fouls. Play a player down for four minutes if charged with a brutality. Leave the game if you're called for three major fouls. Understand that a ref can call "advantage" if it is better to keep playing than take a foul.

Your tomato plants need between 4-6 hours of total sun per day in order to grow and eventually produce fruit. If needed, place your pots on dollies and roll them to where they’ll get sun. You can also set your pots in front of a sun lamp indoors.  Keep the sun lamp at least 6 inches (15 cm) away from the pots to avoid burning the plants. If you’ve planted tomato seeds, keep them warm at night by covering the top of each pot tightly with plastic wrap. Then, remove it at the start of each day. Position the netting so that it encloses the entire cage, including the top. Then, fold the netting over the upper cage rims. Secure the netting to the rims using clothespins or other sturdy clips.  The netting helps to keep insects, such as tomato worms and stink bugs, away from the plant. It also helps to filter the sun’s rays to prevent leaf burning. If you do find insects on your plants, try using a mild insecticide. There are both natural and manufactured options available, depending on the offending pest. Be sure to thoroughly rinse any insecticide-treated tomatoes before you eat them. If the soil is dry for .5 in (1.3 cm) down or if your plants look slightly wilted at the end of the day, then they need to be watered. Keep watering until you see water coming out of the pot’s bottom drain holes. This means that the water has saturated the soil from top to bottom.  Vary your watering schedule depending on the season and temperature. On hot days, you may need to water daily. When the weather is mild, once weekly might suffice. When you are finished watering, drain off any remaining water from the saucer. Letting the water sit in the saucer can cause root rot. Try to water your tomatoes during the daytime. Evening or nighttime water can encourage the growth of fungus. The fruits should almost be completely red with only trace amounts of green remaining. Ripe tomatoes can be plucked by gently pulling at the stem with your fingers. Or, use a pair of garden shears to snip them off their branches. Note that some varieties of tomatoes (check your variety) are naturally striped, green, or otherwise not like an ordinary red tomato when mature.

Position the pot so that it gets 4-6 hours of sun each day. Wrap nylon netting around the tomato cage. Water your tomatoes as often as necessary in order to keep the soil moist. Harvest your tomatoes one-by-one once they develop their red color.
