Q: Following a series of invasions beginning shortly after their conquest of England in 1066, the Normans seized much of Wales and established quasi-independent Marcher lordships, owing allegiance to the English crown. However, Welsh principalities such as Gwynedd, Powys and Deheubarth survived and from the end of the 11th century, the Welsh began pushing back the Norman advance. Over the following century the Welsh recovery fluctuated and the English kings, notably Henry II, several times sought to conquer or establish suzerainty over the native Welsh principalities. Nevertheless, by the end of the 12th century the Marcher lordships were reduced to the south and south east of the country. The principality of Gwynedd was the dominant power in Wales in the first half of the 13th century, with Powys and Deheubarth becoming tributary states. Gwynedd's princes now assumed the title "Prince of Wales". But war with England in 1241 and 1245, followed by a dynastic dispute in the succession to the throne, weakened Gwynedd and allowed Henry III to seize Perfeddwlad . However, from 1256 a resurgent Gwynedd under Llywelyn ap Gruffudd resumed the war with Henry and took back Perfeddwlad. By the Treaty of Montgomery of 1267, peace was restored and, in return for doing homage to the English king, Llywelyn was recognised as Prince of Wales and his re-conquest of Perfeddwlad was accepted by Henry. However, sporadic warfare between Llywelyn and some of the Marcher Lords, such as Gilbert de Clare, Roger Mortimer and Humphrey de Bohun continued.
Which happened first, Llywelyn ap Gruffudd taking back Perfeddwlad or the Treaty of Montgomery?

A: took back Perfeddwlad

Q: Wholesale and retail trade is the largest sector in the citys economy, contributing 24.0 percent of Bangkoks gross provincial product. It is followed by manufacturing (14.3%); real estate, renting and business activities (12.4%); transport and communications (11.6%); and financial intermediation (11.1%). Bangkok alone accounts for 48.4 percent of Thailands service sector, which in turn constitutes 49.0 percent of GDP. When the Bangkok Metropolitan Region is considered, manufacturing is the most significant contributor at 28.2 percent of the gross regional product, reflecting the density of industry in the Bangkoks neighbouring provinces. Automotive industry in Thailand based around Greater Bangkok is the largest production hub in Southeast Asia. Tourism is also a significant contributor to Bangkoks economy, generating 427.5bn ($13.38bn) in revenue in 2010.
How many more percentage points do wholesale and retail trade contribute to Bangkok's gross provincial product than real estate, renting, and business activities?

A: 11.6

Q: About 25,000,000 people in the worlds thirty richest countries will have lost their jobs between the end of 2007 and the end of 2010 as the economic downturn pushes most countries into recession. In April 2010, the U.S. unemployment rate was 9.9%, but the governments broader U-6 unemployment rate was 17.1%. In April 2012, the unemployment rate was 4.6% in Japan. In a 2012 news story, the Financial Post reported, "Nearly 75 million youth are unemployed around the world, an increase of more than 4 million since 2007. In the European Union, where a debt crisis followed the financial crisis, the youth unemployment rate rose to 18% last year from 12.5% in 2007, the ILO report shows." In March 2018, according to U.S. Unemployment Rate Statistics, the unemployment rate was 4,1%, so it is below to 4.5 to 5.0%, which is the norm, this means that there is still need of employees to work.
Which country had a lower unemployment rate, the U.S. in 2010, or Japan in 2012?

A:
4.6% in Japan
