QUES: Palermo experiences a hot-summer Mediterranean climate (Koppen climate classification: Csa). Winters are cool and wet, while summers are hot and dry. Temperatures in autumn and spring are usually mild. Palermo is one of the warmest cities in Europe (mainly due to its warm nights), with an average annual air temperature of 18.5 C (65.3 F). It receives approximately 2,530 hours of sunshine per year. Snow is usually a rare occurrence, but it does occur occasionally if there is a cold front, as the Apennines are too distant to protect the island from cold winds blowing from the Balkans, and the mountains surrounding the city facilite the formation of snow accumulation in Palermo, especially at night. Between the 1940s and the 2000s there have been eleven times when considerable snowfall has occurred: In 1949, in 1956, when the minimum temperature went down to 0 C (32 F) and the city was blanketed by several centimeters of snow. Snow also occurred in 1999, 2009 and 2015. The average annual temperature of the sea is above 19 C (66 F); from 14 C (57 F) in February to 26 C (79 F) in August. In the period from May to November, the average sea temperature exceeds 18 C (64 F) and in the period from June to October, the average sea temperature exceeds 21 C (70 F).

QUES: At a professional level, most matches produce only a few goals. For example, the 200506 season of the English Premier League produced an average of 2.48 goals per match. The Laws of the Game do not specify any player positions other than goalkeeper, but a number of specialised roles have evolved. Broadly, these include three main categories: strikers, or forwards, whose main task is to score goals; defenders, who specialise in preventing their opponents from scoring; and midfielders, who dispossess the opposition and keep possession of the ball to pass it to the forwards on their team. Players in these positions are referred to as outfield players, to distinguish them from the goalkeeper. These positions are further subdivided according to the area of the field in which the player spends most time. For example, there are central defenders, and left and right midfielders. The ten outfield players may be arranged in any combination. The number of players in each position determines the style of the team's play; more forwards and fewer defenders creates a more aggressive and offensive-minded game, while the reverse creates a slower, more defensive style of play. While players typically spend most of the game in a specific position, there are few restrictions on player movement, and players can switch positions at any time. The layout of a team's players is known as a formation. Defining the team's formation and tactics is usually the prerogative of the team's manager.
