It is very rare for top clubs to miss the competition, although it can happen in exceptional circumstances. Defending holders Manchester United did not enter the 19992000 FA Cup, as they were already in the inaugural Club World Championship, with the club stating that entering both tournaments would overload their fixture schedule and make it more difficult to defend their Champions League and Premiership titles. The club claimed that they did not want to devalue the FA Cup by fielding a weaker side. The move benefited United as they received a two-week break and won the 19992000 league title by an 18-point margin, although they did not progress past the group stage of the Club World Championship. The withdrawal from the FA Cup, however, drew considerable criticism as this weakened the tournament's prestige and Sir Alex Ferguson later admitted his regret regarding their handling of the situation.
Why did they miss that competition?
A: The club claimed that they did not want to devalue the FA Cup by fielding a weaker side.

In 1579 the northern seven provinces signed the Union of Utrecht, in which they decided to join forces against Spanish rule. The Union of Utrecht is seen as the beginning of the Dutch Republic. In 1580 the new and predominantly Protestant state abolished the bishoprics, including the archbishopric of Utrecht. The stadtholders disapproved of the independent course of the Utrecht bourgeoisie and brought the city under much more direct control of the republic; which shifted the power towards its dominant province Holland. This was the start of a long period of stagnation of trade and development in Utrecht. Utrecht remained an atypical city in the new republic with about 40% Catholic in the mid-17th century, and even more among the elite groups, who included many rural nobility and gentry with town houses there.
What union ended the Dutch Republic?

To make pulp from wood, a chemical pulping process separates lignin from cellulose fibres. This is accomplished by dissolving lignin in a cooking liquor, so that it may be washed from the cellulose; this preserves the length of the cellulose fibres. Paper made from chemical pulps are also known as wood-free papersnot to be confused with tree-free paper; this is because they do not contain lignin, which deteriorates over time. The pulp can also be bleached to produce white paper, but this consumes 5% of the fibres; chemical pulping processes are not used to make paper made from cotton, which is already 90% cellulose.
What percentage of fibres are used in the bleaching process?
A:
unanswerable
