P: The reported prevalence of TS varies "according to the source, age, and sex of the sample; the ascertainment procedures; and diagnostic system", with a range reported between .4% and 3.8% for children ages 5 to 18. Robertson (2011) says that 1% of school-age children have Tourettes. According to Lombroso and Scahill (2008), the emerging consensus is that .1 to 1% of children have Tourettes, with several studies supporting a tighter range of .6 to .8%. Bloch and Leckman (2009) and Swain (2007) report a range of prevalence in children of .4 to .6%, Knight et al. (2012) estimate .77% in children, and Du et al. (2010) report that 1 to 3% of Western school-age children have Tourettes.
Answer this: Which study reports a higher percentage of children have Tourettes, Bloch and Leckman or Knight et al.?

A: Knight et al.


P:  On October 14, 2007 Charles Woodson picked up a Santana Moss fumble and returned it 57&#160;yards for a go ahead touchdown in a 17-14 victory over the Washington Redskins. He also recorded an interception in the game, his first of the season. This was the 12 straight game that Green Bay has recorded an interception, making it a new team record surpassing an 11-game stretch in 1984-1985. In the third quarter, Redskins safety Sean Taylor intercepted a Brett Favre pass making Favre the career interception leader in NFL history, eclipsing George Blanda's record of 277 interceptions. Favre threw two interceptions for the game. Woodson was named the NFC's Defensive Player of the Week for his performance versus the Redskins. It was the first time he has received this award. With the win, the Packers entered its bye week at 5-1.
Answer this: How many more games had the Packers won than lost going into their bye week?

A: 4


P: The Conquest of Wales by Edward I, sometimes referred to as the Edwardian Conquest of Wales, took place between 1277 and 1283. It resulted in the defeat and annexation of the Principality of Wales, and the other last remaining independent Welsh principalities, by Edward I, King of England. By the 13th century Wales was divided between native Welsh principalities and the territories of the Anglo-Norman Marcher lords. The leading principality was Gwynedd whose princes had gained control of the greater part of the country, making the other remaining Welsh princes their vassals, and had taken the title Prince of Wales. Although English monarchs had made several attempts to seize control of the native Welsh territories, it was not until Edward's war of conquest against Llywelyn ap Gruffudd  of 1277 to 1283 that this was achieved on a lasting basis. In two campaigns, in 1277 and 1282/1283 respectively, Edward first significantly reduced the territory of the Principality of Wales and then completely overran it, as well as the other remaining Welsh principalities. Most of the conquered territory was retained as a royal fief, and these lands subsequently became, by custom, the territorial endowment of the heir to the English throne with the title Prince of Wales. The remainder would be granted to Edward's supporters as new Marcher lordships. Although the territories would not be effectively incorporated into the Kingdom of England until the Laws in Wales Acts 1535-1542, Edward's conquest marked the end of Welsh independence.
