Problem: Umayyad Caliphate:

According to tradition, the Umayyad family (also known as the Banu Abd-Shams) and Muhammad both descended from a common ancestor, Abd Manaf ibn Qusai, and they originally came from the city of Mecca. Muhammad descended from Abd Manaf via his son Hashim, while the Umayyads descended from Abd Manaf via a different son, Abd-Shams, whose son was Umayya. The two families are therefore considered to be different clans (those of Hashim and of Umayya, respectively) of the same tribe (that of the Quraish). However Muslim Shia historians suspect that Umayya was an adopted son of Abd Shams so he was not a blood relative of Abd Manaf ibn Qusai. Umayya was later discarded from the noble family. Sunni historians disagree with this and view Shia claims as nothing more than outright polemics due to their hostility to the Umayyad family in general. They point to the fact that the grand sons of Uthman, Zaid bin amr bin uthman bin affan and Abdullah bin Amr bin Uthman got married to the Sukaina and Fatima the daughters of Hussein son of Ali to show closeness of Banu hashem and Bani Ummayah.

What is another term for the Umayyads?
---
A: Banu Abd-Shams

Problem: Josip Broz Tito:

Josip Broz was born to a Croat father and Slovene mother in the village of Kumrovec, Croatia. Drafted into military service, he distinguished himself, becoming the youngest Sergeant Major in the Austro-Hungarian Army of that time. After being seriously wounded and captured by the Imperial Russians during World War I, Josip was sent to a work camp in the Ural Mountains. He participated in the October Revolution, and later joined a Red Guard unit in Omsk. Upon his return home, Broz found himself in the newly established Kingdom of Yugoslavia, where he joined the Communist Party of Yugoslavia (KPJ).

Tito joined which unit in Omsk?
---
A: Red Guard

Problem: Incandescent light bulb:

While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.

What is the advantage of using inert gas in a light bulb?
---
A: reduces filament evaporation

Problem: Gamal Abdel Nasser:

On 30 March, Nasser proclaimed a manifesto stipulating the restoration of civil liberties, greater parliamentary independence from the executive, major structural changes to the ASU, and a campaign to rid the government of corrupt elements. A public referendum approved the proposed measures in May, and held subsequent elections for the Supreme Executive Committee, the ASU's highest decision-making body. Observers noted that the declaration signaled an important shift from political repression to liberalization, although its promises would largely go unfulfilled.

How did Nasser want to change the relationship between parliament and the executive?
---
A:
independence
