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: Over the Rainbow is the debut album of the child singer Connie Talbot, and was released 26 November 2007 by Rainbow Recording Company. Talbot, who had entered the public eye after her appearance on the first series of Britain's Got Talent at age six, signed with Rainbow, an independent label, after briefly recording with Sony BMG. Over the Rainbow consists entirely of covers of pop and Christmas songs, and was recorded primarily in a spare room in the house of Talbot's aunt, in an attempt not to interrupt Talbot's childhood by disrupting her regular activities. Although public appearances were initially kept to a minimum, Talbot did make appearances to promote the album, and performed in public several times after the British release.
Over the Rainbow received poor reviews. Though praising Talbot's voice, critics noted a lack of depth in the performances, and questioned the appropriateness of releasing and rating work by such a young artist. The album peaked at number 35 on the UK Albums Chart. Despite its poor chart performance, additional copies of the album had to be pressed after sales were higher than expected. Talbot later toured Asia in support of the album; Over the Rainbow achieved more success on Asian charts, reaching number one in Taiwan, South Korea and Hong Kong.
Over the Rainbow was rereleased on 18 June 2008 with an updated track list, replacing some of the Christmas-themed tracks of the original with more general covers. The first single from the album, a cover of Bob Marley's "Three Little Birds," was released in June 2008, and a music video for the song was shot in Jamaica. On 14 October, the album was released in the US, appearing on several Billboard charts. Talbot visited the US to promote the album, appearing on national television.

Answer: What is the name of the company that Connie Talbot first recorded with?

Question: Passage: As the purge claimed the lives of so many prominent Germans, it could hardly be kept secret. At first, its architects seemed split on how to handle the event. Goring instructed police stations to burn "all documents concerning the action of the past two days." Meanwhile, Goebbels tried to prevent newspapers from publishing lists of the dead, but at the same time used a July 2 radio address to describe how Hitler had narrowly prevented Rohm and Schleicher from overthrowing the government and throwing the country into turmoil. Then, on July 13, 1934, Hitler justified the purge in a nationally broadcast speech to the Reichstag:
If anyone reproaches me and asks why I did not resort to the regular courts of justice, then all I can say is this. In this hour I was responsible for the fate of the German people, and thereby I became the supreme judge of the German people. I gave the order to shoot the ringleaders in this treason, and I further gave the order to cauterise down to the raw flesh the ulcers of this poisoning of the wells in our domestic life. Let the nation know that its existencewhich depends on its internal order and securitycannot be threatened with impunity by anyone! And let it be known for all time to come that if anyone raises his hand to strike the State, then certain death is his lot.
Concerned with presenting the massacre as legally sanctioned, Hitler had the cabinet approve a measure on July 3 that declared, "The measures taken on June 30, July 1 and 2 to suppress treasonous assaults are legal as acts of self-defence by the State." Reich Justice Minister Franz Gurtner, a conservative who had been Bavarian Justice Minister in the years of the Weimar Republic, demonstrated his loyalty to the new regime by drafting the statute, which added a legal veneer to the purge. Signed into law by Hitler, Gurtner, and Minister of the Interior Wilhelm Frick, the "Law Regarding Measures of State Self-Defence" retroactively legalised the murders committed during the purge. Germany's legal establishment further capitulated to the regime when the country's leading legal scholar, Carl Schmitt, wrote an article defending Hitler's July 13 speech. It was named "The Fuhrer Upholds the Law.".

Answer: What is the full name of the person who signed the "Law regarding Measures of State Self-Defense" with Hitler and Frick?

Question: Passage: The idea of building a memorial to honor soldiers killed in action during the Latvian War of Independence first emerged in the early 1920s. On July 27, 1922, the Prime Minister of Latvia, Zigfrids Anna Meierovics, ordered rules to be drawn up for a contest for designs of a "memorial column". The winner of this contest was a scheme proposing a column 27 meters (89 ft) tall with reliefs of the official symbols of Latvia and bas-reliefs of Krisjanis Barons and Atis Kronvalds. It was later rejected after a protest from 57 artists. In October 1923, a new contest was announced, using for the first time the term "Freedom Monument". The contest ended with two winners, and a new closed contest was announced in March 1925, but, due to disagreement within the jury, there was no result.Finally in October 1929, the last contest was announced. The winner was the design "Shine like a star!" (Latvian: "Mirdzi ka zvaigzne!") by sculptor Karlis Zale, who had had success in the previous contests as well. After minor corrections made by the author and supervising architect Ernests Stalbergs, construction began on November 18, 1931. Financed by private donations, the monument was erected by the entrance to the old town, in the same place where the previous central monument of Riga, a bronze equestrian statue of the Russian Emperor Peter the Great had stood from 1910 until the outbreak of World War I. It was calculated in 1935, the year when the monument was unveiled, that in four years of construction 308,000 man-hours were required to work the stone materials alone: 130 years would have been required if one person were to carry out the work using the most advanced equipment of the time. The total weight of materials used was about 2,500 tons: such a quantity of materials would have required about 200 freight cars if transported by railway.

Answer:
How many tons of materials were used to build the memorial that was first thought about being built in the early 1920s?
