question:
Passage: The Finnish and Baltic invasions began a deterioration of relations between the Soviets and Germany. Stalin's invasions were a severe irritant to Berlin, as the intent to accomplish these was not communicated to the Germans beforehand, and prompted concern that Stalin was seeking to form an anti-German bloc. Molotov's reassurances to the Germans, and the Germans' mistrust, intensified. On June 16, as the Soviets invaded Lithuania, but before they had invaded Latvia and Estonia, Ribbentrop instructed his staff "to submit a report as soon as possible as to whether in the Baltic States a tendency to seek support from the Reich can be observed or whether an attempt was made to form a bloc."
answer:
Who wanted to know the moment an pro-german bloc was to form?

question:
Passage: Terra preta (black earth), which is distributed over large areas in the Amazon forest, is now widely accepted as a product of indigenous soil management. The development of this fertile soil allowed agriculture and silviculture in the previously hostile environment; meaning that large portions of the Amazon rainforest are probably the result of centuries of human management, rather than naturally occurring as has previously been supposed. In the region of the Xingu tribe, remains of some of these large settlements in the middle of the Amazon forest were found in 2003 by Michael Heckenberger and colleagues of the University of Florida. Among those were evidence of roads, bridges and large plazas.
answer:
Terra preta is distributor over a small area of what?

Passage: The Palacio do Planalto is the official workplace of the President of Brazil. It is located at the Praca dos Tres Poderes in Brasilia. As the seat of government, the term "Planalto" is often used as a metonym for the executive branch of government. The main working office of the President of the Republic is in the Palacio do Planalto. The President and his or her family do not live in it, rather in the official residence, the Palacio da Alvorada. Besides the President, senior advisors also have offices in the "Planalto," including the Vice-President of Brazil and the Chief of Staff. The other Ministries are along the Esplanada dos Ministerios. The architect of the Palacio do Planalto was Oscar Niemeyer, creator of most of the important buildings in Brasilia. The idea was to project an image of simplicity and modernity using fine lines and waves to compose the columns and exterior structures. The Palace is four stories high, and has an area of 36,000 m2. Four other adjacent buildings are also part of the complex.
answer:
How many floors are in the Palacio da Alvoarada?
