Problem: Read the following paragraph and extract the answer for the question: What was the last name of Lissitzky's lifetime childhood friend?  Lissitzky was born on November 23, 1890 in Pochinok, a small Jewish community 50 kilometres (31 mi) southeast of Smolensk, former Russian Empire. During his childhood, he lived and studied in the city of Vitebsk, now part of Belarus, and later spent 10 years in Smolensk living with his grandparents and attending the Smolensk Grammar School, spending summer vacations in Vitebsk. Always expressing an interest and talent in drawing, he started to receive instruction at 13 from Yehuda Pen, a local Jewish artist, and by the time he was 15 was teaching students himself. In 1909, he applied to an art academy in Saint Petersburg, but was rejected. While he passed the entrance exam and was qualified, the law under the Tsarist regime only allowed a limited number of Jewish students to attend Russian schools and universities. Like many other Jews then living in the Russian Empire, Lissitzky went to study in Germany. He left in 1909 to study architectural engineering at a Technische Hochschule in Darmstadt, Germany. During the summer of 1912, Lissitzky, in his own words, "wandered through Europe", spending time in Paris and covering 1,200 kilometres (750 mi) on foot in Italy, teaching himself about fine art and sketching architecture and landscapes that interested him. His interest in ancient Jewish culture had originated during the contacts with a Paris-based group of Russian Jews led by sculptor Ossip Zadkine, a lifetime friend of Lissitzky since early childhood, who exposed Lissitzky to conflicts between different groups within the diaspora. Also in 1912 some of his pieces were included for the first time in an exhibit by the St. Petersburg Artists Union; a notable first step. He remained in Germany until the outbreak of World War I, when he was forced to return home through Switzerland and the Balkans, along with many of his countrymen, including other expatriate artists born in the former Russian Empire, such as Wassily Kandinsky and Marc Chagall.Upon his return to Moscow, Lissitzky attended the Polytechnic...

A: Zadkine

Problem: Given the question: Read the following paragraph and extract the answer for the question: What is the last name of the person who tried to get in touch with Speer by telepathy one New Year's Eve?  In 1951, with secret means of communications established, Wolters sent his first letter to Speer in five years.  He suggested that Speer move ahead with his memoirs.  In January 1953, Speer began work on his draft memoirs, and over the next year lengthy missives, sometimes written on tobacco wrappings or candy wrappers but most often on toilet paper, made their way to Wolters' office in Coesfeld.  Marion Riesser, who had continued as Wolters' secretary as he began private architectural practice, transcribed these notes into as many as forty closely typed pages per missive, and the draft totalled 1,100 pages.  Wolters objected that Speer called Hitler a criminal in the draft, and Speer presciently observed that he would likely lose a good many friends were the memoirs ever to be published.  Wolters had come to believe that reports of Nazi genocide were exaggerated by a factor of at least ten, that Hitler had not been given credit for the things he did right and that Germany had been harshly treated by the Allies.In the mid-1950s, Wolters quarrelled with Kempf who effectively dropped out of the network for a number of years, adding to the burden on Wolters and Riesser.  While Speer's pleas for his former associate and his former secretary to work together eventually brought about a healing of the breach, this was to some degree superficial as Kempf was aware that Wolters, even then, disagreed with Speer's opinions.  Wolters questioned Speer's readiness to accept responsibility for the Nazi regime's excesses and did not believe Speer had anything to apologise for, though the strength of his feelings on this point was kept from Speer—but not from Kempf and Riesser.Wolters was tireless in his efforts on behalf of Speer and his family to such an extent that his son, Fritz, later expressed feelings of neglect.  For Speer's fiftieth birthday in March 1955, Wolters gathered letters from many of Speer's friends and wartime associates, and saw to it that they made their way inside the walls of Spandau in time for...

[Q]: Read the following paragraph and extract the answer for the question: What albums did the original lead guitarist for the band that had a member die in August 1992 perform lead vocals on?  Lukather is the original lead guitarist for Toto, serving in that capacity for the band's entire history, as well as a lead and backing vocalist and composer. Lukather won three of his five Grammy Awards for work with Toto, twice as an artist and once as a producer. David Paich led the band's songwriting efforts during the development of 1978's Toto—he penned all but two of the album's tracks, including all four of its singles. Lukather also credits Jeff Porcaro for his leadership within the band during that period. However, Lukather's role in Toto evolved over time owing to the changing needs of the band. In August 1992, Jeff Porcaro collapsed while doing yard work at home and subsequently died of heart failure. The death profoundly affected Toto and Lukather in particular, who felt that he needed to step up and make sure the band kept going. Thus, he began taking more of a leadership role. Toto went through several lead vocalists over the years, including Bobby Kimball, Fergie Frederiksen, and Joseph Williams. After the 1990 dismissal of their fourth vocalist, Jean-Michel Byron, Toto was without a lead singer until around 1997; Lukather assumed most of the vocal duties for the band during that time. He performed lead vocals for every track on 1992's Kingdom of Desire and 1995's Tambu except for two instrumental tracks. The Tambu single "I Will Remember", co-written by Lukather and Stan Lynch, reached number 64 on UK charts. Some Tambu reviewers contrasted Lukather's vocals with those of former singers Kimball and Williams (and indeed, heavily criticized the entire album), some concert reviewers noted that he struggled vocally on certain songs, and a number of backup singers and guest vocalists accompanied the band's live shows during that period. It was not until Toto brought back Williams and Kimball to collaborate on 1998's Toto XX that Lukather returned predominantly to the role of backup vocalist.Lukather's songwriting contributions grew from a smattering of tracks on early Toto albums to co-writing...
