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.

Question: Passage: In 1990, the Rwandan Patriotic Front (RPF), a rebel group composed of nearly 500,000 Tutsi refugees, invaded northern Rwanda from their base in Uganda, initiating the Rwandan Civil War. The group condemned the Hutu-dominated government for failing to democratize and confront the problems facing these refugees. Neither side was able to gain a decisive advantage in the war, but by 1992 it had weakened Habyarimana's authority; mass demonstrations forced him into a coalition with the domestic opposition and eventually to sign the 1993 Arusha Accords with the RPF. The cease-fire ended on 6 April 1994 when Habyarimana's plane was shot down near Kigali Airport, killing him. The shooting down of the plane served as the catalyst for the Rwandan genocide, which began within a few hours. Over the course of approximately 100 days, around 800,000 Tutsi and politically moderate Hutu were killed in well-planned attacks on the orders of the interim government. Many Twa were also killed, despite not being directly targeted.The Tutsi RPF restarted their offensive, and took control of the country methodically, gaining control of the whole country by mid-July. The international response to the genocide was limited, with major powers reluctant to strengthen the already overstretched UN peacekeeping force. When the RPF took over, approximately two million Hutu fled to neighbouring countries, in particular Zaïre, fearing reprisals; additionally, the RPF-led army was a key belligerent in the First and Second Congo Wars. Within Rwanda, a period of reconciliation and justice began, with the establishment of the International Criminal Tribunal for Rwanda (ICTR) and the reintroduction of Gacaca, a traditional village court system. Since 2000 Rwanda's economy, tourist numbers, and Human Development Index have grown rapidly; between 2006 and 2011 the poverty rate reduced from 57% to 45%, while life expectancy rose from 46.6 years in 2000 to 59.7 years in 2015.

Answer: What is the name of the country that the Tutsi RPF gained control of by mid-July?


Question: Passage: Geologically, Portland is separated into two areas; the steeply sloping land at its north end called Underhill, and the larger, gently sloping land to the south, called Tophill. Portland stone lies under Tophill; the strata decline at a shallow angle of around 1.5 degrees, from a height of 151 metres (495 ft) near the Verne in the north, to just above sea level at Portland Bill. The geology of Underhill is different to Tophill; Underhill lies on a steep escarpment composed of Portland Sand, lying above a thicker layer of Kimmeridge Clay, which extends to Chesil Beach and Portland Harbour. This Kimmeridge Clay has resulted in a series of landslides, forming West Weares and East Weares.2.4 kilometres (1.5 mi) underneath south Dorset lies a layer of Triassic rock salt, and Portland is one of four locations in the United Kingdom where the salt is thick enough to create stable cavities. Portland Gas applied to excavate 14 caverns to store 1,000,000,000 cubic metres (3.5×1010 cu ft) of natural gas, which is one percent of the UK's total annual demand. It was proposed that the caverns should be connected to the National gas grid at Mappowder via a 37-kilometre (23 mi) pipeline. Plans had it that the surface facilities should be complete to store the first gas in 2011, and the entire cavern space available for storage in winter 2013. As part of the £350 million scheme, the Grade II listed former Old Engine Shed would be converted into a £1.5 million educational centre with a café and an exhibition space about the geology of Portland.

Answer: What is the full name of the acronym UK?


Question: Passage: Steve MacKendrick, nicknamed "Canada" because he claims he is from there, volunteers in 1940 for the British military's parachute training facility. He obviously has a good deal more experience and leadership skills than he lets on. Canada tries to become better acquainted with a pretty parachute rigger named Penny Gardner. She is initially put off by his attitude, but they eventually start dating. Both Penny and his new commander, Major Snow, see potential (and a mystery that does not add up) in him, despite his strong efforts to avoid assuming any responsibility. Canada turns down Snow's offer to send him to officer school.
After completing parachute school, Canada's unit goes on a raid on the German radar station at Bruneval. An RAF radar expert, Flight Sergeant Box, accompanies the raiders to retrieve a key component to take back to Britain. The mission is a success, but Corporal Dawes, one of the men in Canada's outfit, hurts both his legs in the drop. 
Back in Britain, after visiting Dawes, Canada is recognised by an American airman. He tells Penny that he resigned his commission from the USAAF after ordering his best friend and co-pilot to parachute out of their bomber when an experimental rocket got stuck. His friend was killed when his parachute did not open properly. Canada blamed himself and refuses any responsibility that might endanger anyone's life. When Snow confronts Canada with what he has learned (from a security investigation that he has ordered), Canada wrongly assumes that Penny told what she learned, and he breaks up with her.

Answer:
Who does Canada believe the parachute rigger tells his USAAF story too?
