Problem: Bras%C3%ADlia:

The Palácio do Planalto is the official workplace of the President of Brazil. It is located at the Praça dos Três Poderes in Brasília. 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 Palácio do Planalto. The President and his or her family do not live in it, rather in the official residence, the Palácio 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 Ministérios. The architect of the Palácio do Planalto was Oscar Niemeyer, creator of most of the important buildings in Brasília. 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.

Who also has offices in the Alvorada?

A: unanswerable


Problem: Computer:

Early digital computers were electromechanical; electric switches drove mechanical relays to perform the calculation. These devices had a low operating speed and were eventually superseded by much faster all-electric computers, originally using vacuum tubes. The Z2, created by German engineer Konrad Zuse in 1939, was one of the earliest examples of an electromechanical relay computer.

When did Konrad Zuse invent the Z2?
---
A: 1939


Problem: Insect:

Traditional morphology-based or appearance-based systematics have usually given the Hexapoda the rank of superclass,:180 and identified four groups within it: insects (Ectognatha), springtails (Collembola), Protura, and Diplura, the latter three being grouped together as the Entognatha on the basis of internalized mouth parts. Supraordinal relationships have undergone numerous changes with the advent of methods based on evolutionary history and genetic data. A recent theory is that the Hexapoda are polyphyletic (where the last common ancestor was not a member of the group), with the entognath classes having separate evolutionary histories from the Insecta. Many of the traditional appearance-based taxa have been shown to be paraphyletic, so rather than using ranks like subclass, superorder, and infraorder, it has proved better to use monophyletic groupings (in which the last common ancestor is a member of the group). The following represents the best-supported monophyletic groupings for the Insecta.

Collembola, protura, and dipkura are in a group called what?
---
A: Entognatha


Problem: Neptune:

Voyager 2 is the only spacecraft that has visited Neptune. The spacecraft's closest approach to the planet occurred on 25 August 1989. Because this was the last major planet the spacecraft could visit, it was decided to make a close flyby of the moon Triton, regardless of the consequences to the trajectory, similarly to what was done for Voyager 1's encounter with Saturn and its moon Titan. The images relayed back to Earth from Voyager 2 became the basis of a 1989 PBS all-night program, Neptune All Night.

What near Neptune did a spacecraft visit dangerously close?
---
A:
Triton
