Problem: Gamal Abdel Nasser:

Nasser's regional position changed unexpectedly when Yemeni officers led by Nasser supporter Abdullah al-Sallal overthrew Imam Badr of North Yemen on 27 September 1962. Al-Badr and his tribal partisans began receiving increasing support from Saudi Arabia to help reinstate the kingdom, while Nasser subsequently accepted a request by Sallal to militarily aid the new government on 30 September. Consequently, Egypt became increasingly embroiled in the drawn-out civil war until it withdrew its forces in 1967. Most of Nasser's old colleagues had questioned the wisdom of continuing the war, but Amer reassured Nasser of their coming victory. Nasser later remarked in 1968 that intervention in Yemen was a "miscalculation".

In what year did Egypt leave Yemen's civil war?

A: 1967


Problem: Cubism:

The leading Cubist architects were Pavel Janák, Josef Gočár, Vlastislav Hofman, Emil Králíček and Josef Chochol. They worked mostly in Prague but also in other Bohemian towns. The best-known Cubist building is the House of the Black Madonna in the Old Town of Prague built in 1912 by Josef Gočár with the only Cubist café in the world, Grand Café Orient. Vlastislav Hofman built the entrance pavilions of Ďáblice Cemetery in 1912–1914, Josef Chochol designed several residential houses under Vyšehrad. A Cubist streetlamp has also been preserved near the Wenceslas Square, designed by Emil Králíček in 1912, who also built the Diamond House in the New Town of Prague around 1913.

Problem: Norfolk Island:

In 1824 the British government instructed the Governor of New South Wales Thomas Brisbane to occupy Norfolk Island as a place to send "the worst description of convicts". Its remoteness, previously seen as a disadvantage, was now viewed as an asset for the detention of recalcitrant male prisoners. The convicts detained have long been assumed to be a hardcore of recidivists, or 'doubly-convicted capital respites' – that is, men transported to Australia who committed fresh colonial crimes for which they were sentenced to death, and were spared the gallows on condition of life at Norfolk Island. However, a recent study has demonstrated, utilising a database of 6,458 Norfolk Island convicts, that the reality was somewhat different: more than half were detained at Norfolk Island without ever receiving a colonial conviction, and only 15% had been reprieved from a death sentence. Furthermore, the overwhelming majority of convicts sent to Norfolk Island had committed non-violent property sentences, and the average length of detention was three years.

Who blocked the Governor of New South Wales Thomas Brisbane from sending the worst convicts to Norfolk Island?

A: unanswerable


Problem: Sexual orientation:

Most definitions of sexual orientation include a psychological component, such as the direction of an individual's erotic desires, or a behavioral component, which focuses on the sex of the individual's sexual partner/s. Some people prefer simply to follow an individual's self-definition or identity. Scientific and professional understanding is that "the core attractions that form the basis for adult sexual orientation typically emerge between middle childhood and early adolescence". Sexual orientation differs from sexual identity in that it encompasses relationships with others, while sexual identity is a concept of self.

When do scientists and professions agree that sexual orientation shows in a person?
---
A:
typically emerge between middle childhood and early adolescence
