[EX Q]: Question: What were the factions in the 1975 civil war? Passage 1:The 84th Regiment of Foot (Royal Highland Emigrants) was a British regiment in the American Revolutionary War that was raised to defend present day Ontario, Quebec and Atlantic Canada from the constant land and sea attacks by American Revolutionaries. The 84th Regiment was also involved in offensive action in the Thirteen Colonies; including North Carolina, South Carolina, Georgia, Virginia and what is now Maine, as well as raids upon Lake Champlain and the Mohawk Valley. The regiment consisted of 2,000 men in twenty companies. The 84th Regiment was raised from Scottish soldiers who had served in the Seven Years' War and stayed in North America. As a result, the 84th Regiment had one of the oldest and most experienced officer corps of any regiment in North America. The Scottish Highland regiments were a key element of the British Army in the American Revolution. The 84th Regiment was clothed, armed and accoutred the same as the Black Watch, with Lieutenant Colonel Allan Maclean commanding the first battalion and Major General John Small of Strathardle commanding the second. The two Battalions operated independently of each other and saw little action together.
 Passage 2:By the mid-1970s, Arafat and his Fatah movement found themselves in a tenuous position. Arafat increasingly called for diplomacy, perhaps best symbolized by his Ten Point Program and his support for a UN Security Council resolution proposed in 1976 calling for a two-state settlement on the pre-1967 borders. But the Rejectionist Front denounced the calls for diplomacy, and a diplomatic solution was vetoed by the United States. In 1975, the increasing tensions between Palestinian militants and Christian militias exploded into the Lebanese Civil War, involving all factions. On 20 January 1976, the PLO took part in the Damour massacre in retaliation to the Karantina massacre. The PLO and Lebanese National Movement attacked the Christian town of Damour, killing 684 civilians and forcing the remainder of the town's population to flee. In 1976 Syria joined the war by invading Lebanon, beginning the 29‑year Syrian occupation of Lebanon, and in 1978 Israel invaded South Lebanon in response to the Coastal Road Massacre, executed by Palestinian militants based in Lebanon.

[EX Q]: Question: Which power-switching election in the 1970s had more total votes? Passage 1:Secretary of State for Employment and Productivity Barbara Castle introduced an Employed Persons (Health and Safety) Bill in 1970 but the debate around the Bill soon generated a belief that it did not address fundamental issues of workplace safety. In the same year, the Occupational Safety and Health Act was passed into United States federal law. As a result, a committee of inquiry chaired by Lord Robens was established towards the end of Harold Wilson's first government. When the Conservative Party came to power following the 1970 United Kingdom general election, they gave Castle's Bill no parliamentary time, preferring to wait for the Robens Report which was published in 1972. Conservative Secretary of State for Employment William Whitelaw introduced a new Bill on 28 January 1974 but Labour were returned to power in the February 1974 United Kingdom general election and the Bill again lost. The new Labour administration finally secured the passage of a Bill that year.

In support of the EP, ATFEH embarked on their first nationwide tour in 2004, during which Welling (violin) parted ways with the band due to personal differences.

 Passage 3:He was a member of the Irish Volunteers and on the outbreak of the 1916 Easter Rising he walked the 26 kilometres to Dublin to fight in the Rising. He was imprisoned in the mass arrests and deportations that followed, and released in 1917. Like many Rising survivors, he joined Sinn Féin, a small separatist party that was wrongly blamed by the British government for the Easter Rising. In the aftermath of the Rising, survivors led by Éamon de Valera took over the party in the struggle for the establishment of an Irish republic. Ua Buachalla was elected as a Sinn Féin MP for Kildare North at the 1918 general election. He served in the First Dáil (1918–1921), and was re-elected to the Second Dáil in 1921 as a Teachta Dála (TD) for Kildare–Wicklow. He sided with de Valera and opposed the Anglo-Irish Treaty. He fought in the Four Courts in the Civil War. Imprisoned in Dundalk jail, he was released by the Anti-Treaty troops in August 1922.
