Q: This task involves creating questions from a given passage that involve some kind of complex reasoning (including numerical reasoning).
The generated questions must require looking at more than one part of the passage to answer. Try to use a variety of reasoning types in your questions (some of the sample reasoning types are illustrated in the 'positive examples' field) and also have a variety of answer types (spans, numbers, dates). A span is a continuous phrase taken directly from the passage or question. In such questions, the answer spans are recommended to be five words. Questions with answer type "number", are expected to start with "How many". For instance, "How long did an event last?" can be phrased as "How many years did an event last?". To increase diversity, try to create more questions for which the answer will be multiple spans. Please create questions that require AT LEAST 2 arithmetic operations as illustrated in the 'positive examples' field. You are encouraged to try DIFFERENT COMBINATIONS of operations and not just limit to the combinations shown in those examples. The more challenging questions you create, the better it is.
Passage: On 13 June 1990, the East German military officially began dismantling the Wall, beginning in Bernauer Strae and around the Mitte district. From there, demolition continued through Prenzlauer Berg/Gesundbrunnen, Helligensee and throughout the city of Berlin until that December 1990. According to estimates by the border troops, a total of around 1.7 million tonnes of building rubble was produced by the demolition. Unofficially, the demolition of the Bornholmer Strae began because of construction work on the railway. This involved a total of 300 GDR border guards and - after 3 October 1990 - 600 Pioneers of the Bundeswehr. These were equipped with 175 trucks, 65 cranes, 55 excavators and 13 bulldozers. Virtually every road that was severed by the Berlin Wall, every road that once linked from West Berlin to East Berlin, was reconstructed and reopened by 1 August 1990. In Berlin alone, 184 km of wall, 154 km border fence, 144 km signal systems and 87 km barrier ditches were removed. What remained were six sections that were to be preserved as a memorial. Various military units dismantled the Berlin/Brandenberg border wall, completing the job in November 1991. Painted wall segments with artistically valuable motifs were put up for auction in 1990 in Berlin and Monte Carlo.
A:
Did more border guards or Pioneers of the Bundeswehr work on construction?
