In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: Following the end of the Second World War, the East German side of the border was guarded initially by the Border Troops (Pogranichnyie Voiska) of the Soviet NKVD (later the KGB). They were supplemented from 1946 by a locally recruited paramilitary force, the German Border Police (Deutsche Grenzpolizei or DGP), before the Soviets handed over full control of the border to the East Germans in 1955/56. In 1961, the DGP was converted into a military force within the National People's Army (Nationale Volksarmee, NVA). The newly renamed Border Troops of the GDR (Grenztruppen der DDR, commonly nicknamed the Grenzer) came under the NVA's Border Command or Grenzkommando. They were responsible for securing and defending the borders with West Germany, Czechoslovakia, Poland, the Baltic Sea and West Berlin. At their peak, the Grenztruppen had up to 50,000 personnel.Around half of the Grenztruppen were conscripts, a lower proportion than in other branches of the East German armed forces. Many potential recruits were screened out as potentially unreliable; for instance, actively religious individuals or those with close relatives in West Germany. They were all subjected to close scrutiny to assure their political reliability and were given intensive ideological indoctrination.A special unit of the Stasi secret police worked covertly within the Grenztruppen, posing as regular border guards, between 1968 and 1985, to weed out potential defectors. One in ten officers and one in thirty enlisted men were said to have been recruited by the Stasi as informers. The Stasi regularly interviewed and maintained files on every guard. Stasi operatives were directly responsible for some aspects of security; passport control stations at crossings were manned by Stasi officers wearing Grenztruppen uniforms.The Grenztruppen were closely watched to ensure that they could not take advantage of their inside knowledge to escape across the border. Patrols, watchtowers and observation posts were always manned by two or three guards at a time. They were not allowed to go out of each other's sight in any circumstances. If a guard attempted to escape, his colleagues were under instructions to shoot him without hesitation or prior warning; 2,500 did escape to the West, 5,500 more were caught and imprisoned for up to five years, and a number were shot and killed or injured in the attempt.
The work of the guards involved carrying out repair work on the defences, monitoring the zone from watchtowers and bunkers and patrolling the line several times a day. Border Reconnaissance (Grenzaufklärungszug or GAK) soldiers, an elite reconnaissance force, carried out patrols and intelligence-gathering on the western side of the fence. Western visitors to the border were routinely photographed by the GAKs, who also oversaw work detachments maintaining the fence. The workers would be covered by machine guns to discourage them from attempting to escape.
What is the nickname of the group that screened out many potential recruits?

Passage: Fort Ticonderoga (), formerly Fort Carillon, is a large 18th-century star fort built by the French at a narrows near the south end of Lake Champlain, in northern New York, in the United States. It was constructed by Canadian-born French military engineer Michel Chartier de Lotbinière, Marquis de Lotbinière between October 1755 and 1757, during the action in the "North American theater" of the Seven Years' War, often referred to in the US as the French and Indian War. The fort was of strategic importance during the 18th-century colonial conflicts between Great Britain and France, and again played an important role during the American Revolutionary War.
The site controlled a river portage alongside the mouth of the rapids-infested La Chute River, in the 3.5 miles (5.6 km) between Lake Champlain and Lake George. It was thus strategically placed for the competition over trade routes between the British-controlled Hudson River Valley and the French-controlled Saint Lawrence River Valley.
The terrain amplified the importance of the site. Both lakes were long and narrow and oriented north–south, as were the many ridge lines of the Appalachian Mountains, which extended as far south as Georgia. The mountains created nearly impassable terrains to the east and west of the Great Appalachian Valley that the site commanded.
The name "Ticonderoga" comes from the Iroquois word tekontaró:ken, meaning "it is at the junction of two waterways".During the 1758 Battle of Carillon, 4,000 French defenders were able to repel an attack by 16,000 British troops near the fort. In 1759, the British returned and drove a token French garrison from the fort. During the American Revolutionary War, when the British controlled the fort, it was attacked in May 1775 in the Capture of Fort Ticonderoga by the  Green Mountain Boys and other state militia under the command of Ethan Allen and Benedict Arnold, who captured it in the surprise attack.  Cannons taken from the fort were transported to Boston to lift its siege by the British, who evacuated the city in March 1776. The Americans held the fort until June 1777, when British forces under General John Burgoyne occupied high ground above it; the threat resulted in the  Continental Army troops being withdrawn from the fort and its surrounding defenses.  The only direct attack on the fort during the Revolution took place in September 1777, when John Brown led 500 Americans in an unsuccessful attempt to capture the fort from about 100 British defenders.
What was the two names of the large 18-century star fort built by the French in norther New York?

Passage: Sissinghurst Castle Garden, at Sissinghurst in the Weald of Kent in England, was created by Vita Sackville-West, poet and writer, and her husband Harold Nicolson, author and diplomat. It is among the most famous gardens in England and is designated Grade I on Historic England's register of historic parks and gardens. It was bought by Sackville-West in 1930, and over the next thirty years, working with, and later succeeded by, a series of notable head gardeners, she and Nicolson transformed a farmstead of "squalor and slovenly disorder" into one of the world's most influential gardens. Following Sackville-West's death in 1962, the estate was donated to the National Trust for Places of Historic Interest or Natural Beauty. It is one of the Trust's most popular properties, with nearly 200,000 visitors in 2017.
The gardens contain an internationally respected plant collection, particularly the assemblage of old garden roses. The writer Anne Scott-James considered the roses at Sissinghurst to be "one of the finest collections in the world". A number of plants propagated in the gardens bear names related to people connected with Sissinghurst or the name of the garden itself. The garden design is based on axial walks that open onto enclosed gardens, termed "garden rooms", one of the earliest examples of this gardening style. Among the individual "garden rooms", the White Garden has been particularly influential, with the horticulturalist Tony Lord describing it as "the most ambitious ... of its time, the most entrancing of its type."The site of Sissinghurst is ancient and has been occupied since at least the Middle Ages. The present-day buildings began as a house built in the 1530s by Sir John Baker. In 1554 Sir John's daughter Cecily married Thomas Sackville, 1st Earl of Dorset, an ancestor of Vita Sackville-West. By the 18th century the Baker's fortunes had waned, and the house, renamed Sissinghurst Castle, was leased to the government to act as a prisoner-of-war camp during the Seven Years' War. The prisoners caused great damage and by the 19th century much of Sir Richard's house had been demolished. In the mid-19th century, the remaining buildings were in use as a workhouse, and by the 20th century Sissinghurst had declined to the status of a farmstead. In 1928 the castle was advertised for sale but remained unsold for two years.
What are the full names of the poet/writer and author/diplomat who are married?
