The problem: Answer a question about this article:
The set of graphic and format characters defined by Unicode does not correspond directly to the repertoire of abstract characters that is representable under Unicode. Unicode encodes characters by associating an abstract character with a particular code point. However, not all abstract characters are encoded as a single Unicode character, and some abstract characters may be represented in Unicode by a sequence of two or more characters. For example, a Latin small letter "i" with an ogonek, a dot above, and an acute accent, which is required in Lithuanian, is represented by the character sequence U+012F, U+0307, U+0301. Unicode maintains a list of uniquely named character sequences for abstract characters that are not directly encoded in Unicode.
How are some abstract characters represented in Unicode?
****
The answer: a sequence of two or more characters


The problem: Answer a question about this article:
In game play, players attempt to create goal-scoring opportunities through individual control of the ball, such as by dribbling, passing the ball to a team-mate, and by taking shots at the goal, which is guarded by the opposing goalkeeper. Opposing players may try to regain control of the ball by intercepting a pass or through tackling the opponent in possession of the ball; however, physical contact between opponents is restricted. Football is generally a free-flowing game, with play stopping only when the ball has left the field of play or when play is stopped by the referee for an infringement of the rules. After a stoppage, play recommences with a specified restart.
Besides a referee interfering, when else is play stopped?
****
The answer: when the ball has left the field of play

In July 2009, Dell apologized after drawing the ire of the Taiwanese Consumer Protection Commission for twice refusing to honour a flood of orders against unusually low prices offered on its Taiwanese website. In the first instance, Dell offered a 19" LCD panel for $15. In the second instance, Dell offered its Latitude E4300 notebook at NT$18,558 (US$580), 70% lower than usual price of NT$60,900 (US$1900). Concerning the E4300, rather than honour the discount taking a significant loss, the firm withdrew orders and offered a voucher of up to NT$20,000 (US$625) a customer in compensation. The consumer rights authorities in Taiwan fined Dell NT$1 million (US$31250) for customer rights infringements. Many consumers sued the firm for the unfair compensation. A court in southern Taiwan ordered the firm to deliver 18 laptops and 76 flat-panel monitors to 31 consumers for NT$490,000 (US$15,120), less than a third of the normal price. The court said the event could hardly be regarded as mistakes, as the prestigious firm said the company mispriced its products twice in Taiwanese website within 3 weeks.
What year did Dell come under fire from the Taiwanese Consumer Protection Commission?
****
The answer: 2009
