Question: The Spanish Empire and other Europeans brought horses to the Americas. Some of these animals escaped and began to breed and increase their numbers in the wild. The re-introduction of the horse, extinct in the Americas for over 7500 years, had a profound impact on Native American culture in the Great Plains of North America and of Patagonia in South America. By domesticating horses, some tribes had great success: horses enabled them to expand their territories, exchange more goods with neighboring tribes, and more easily capture game, especially bison.
Try to answer this question if possible: What enabled some tribes to expand territory, increase trade and capture more game?
Answer: horses

Question: In the controversial elections in 2002, Sassou won with almost 90% of the vote cast. His two main rivals, Lissouba and Bernard Kolelas, were prevented from competing and the only remaining credible rival, Andre Milongo, advised his supporters to boycott the elections and then withdrew from the race. A new constitution, agreed upon by referendum in January 2002, granted the president new powers, extended his term to seven years, and introduced a new bicameral assembly. International observers took issue with the organization of the presidential election and the constitutional referendum, both of which were reminiscent in their organization of Congo's era of the one-party state. Following the presidential elections, fighting restarted in the Pool region between government forces and rebels led by Pastor Ntumi; a peace treaty to end the conflict was signed in April 2003.
Try to answer this question if possible: When did Bernard Kolelas win the election?
Answer: unanswerable
Question: An alternative concept is that they formed closer to the Sun, where the matter density was higher, and then subsequently migrated to their current orbits after the removal of the gaseous protoplanetary disc. This hypothesis of migration after formation is favoured, due to its ability to better explain the occupancy of the populations of small objects observed in the trans-Neptunian region. The current most widely accepted explanation of the details of this hypothesis is known as the Nice model, which explores the effect of a migrating Neptune and the other giant planets on the structure of the Kuiper belt.
Try to answer this question if possible: If Neptune formed closer to the sun, what caused it to migrate to it's current orbit?
Answer:
removal of the gaseous protoplanetary disc
