Problem: Sexual orientation:

More recently, scientists have started to focus on measuring changes in brain activity related to sexual arousal, by using brain-scanning techniques. A study on how heterosexual and homosexual men's brains react to seeing pictures of naked men and women has found that both hetero- and homosexual men react positively to seeing their preferred sex, using the same brain regions. The only significant group difference between these orientations was found in the amygdala, a brain region known to be involved in regulating fear.

How do scientiest measure brain activity?

A: by using brain-scanning techniques


Problem: Gothic architecture:

Secular Gothic architecture can also be found in a number of public buildings such as town halls, universities, markets or hospitals. The Gdańsk, Wrocław and Stralsund town halls are remarkable examples of northern Brick Gothic built in the late 14th centuries. The Belfry of Bruges or Brussels Town Hall, built during the 15th century, are associated to the increasing wealth and power of the bourgeoisie in the late Middle Ages; by the 15th century, the traders of the trade cities of Burgundy had acquired such wealth and influence that they could afford to express their power by funding lavishly decorated buildings of vast proportions. This kind of expressions of secular and economic power are also found in other late mediaeval commercial cities, including the Llotja de la Seda of Valencia, Spain, a purpose built silk exchange dating from the 15th century, in the partial remains of Westminster Hall in the Houses of Parliament in London, or the Palazzo Pubblico in Siena, Italy, a 13th-century town hall built to host the offices of the then prosperous republic of Siena. Other Italian cities such as Florence (Palazzo Vecchio), Mantua or Venice also host remarkable examples of secular public architecture.

Problem: FA Cup:

Beginning in August, the competition proceeds as a knockout tournament throughout, consisting of twelve rounds, a semi-final and then a final, in May. A system of byes ensures clubs above Level 9 and 10 enter the competition at later stages. There is no seeding, the fixtures in each round being determined by a random draw. Prior to the semi-finals, fixtures ending in a tie are replayed once only. The first six rounds are qualifiers, with the draws organised on a regional basis. The next six rounds are the "proper" rounds where all clubs are in one draw.

When is the final?
---
A: May


Problem: Heian period:

The Fujiwara controlled the throne until the reign of Emperor Go-Sanjō (1068-1073), the first emperor not born of a Fujiwara mother since the ninth century. Go-Sanjo, determined to restore imperial control through strong personal rule, implemented reforms to curb Fujiwara influence. He also established an office to compile and validate estate records with the aim of reasserting central control. Many shōen were not properly certified, and large landholders, like the Fujiwara, felt threatened with the loss of their lands. Go-Sanjo also established the In-no-cho (ja:院庁 Office of the Cloistered Emperor), which was held by a succession of emperors who abdicated to devote themselves to behind-the-scenes governance, or insei.

Who was the last emperor born to a Fujiwara mother?
