Problem: This influx was compounded by the decline of the Western Sudanic Mali Empire in 1375 and the Songhai Empire in 1591. Additionally, as inland regions underwent desertification, inhabitants moved to the wetter coast. These new inhabitants brought skills such as cotton spinning, cloth weaving, iron smelting, rice and sorghum cultivation, and social and political institutions from the Mali and Songhai empires. Shortly after the Mane conquered the region, the Vai people of the former Mali Empire immigrated into the Grand Cape Mount region. The ethnic Kru opposed the influx of Vai, forming an alliance with the Mane to stop further influx of Vai.[citation needed]
What group wanted to extend the influence of the Vai?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
In the 1990s, Dell switched from using primarily ATX motherboards and PSU to using boards and power supplies with mechanically identical but differently wired connectors. This meant customers wishing to upgrade their hardware would have to replace parts with scarce Dell-compatible parts instead of commonly available parts. While motherboard power connections reverted to the industry standard in 2003, Dell continues to remain secretive about their motherboard pin-outs for peripherals (such as MMC readers and power on/off switches and LEDs).
With what kind of parts weren't consumers able to upgrade their Dell systems with?
A: unanswerable

Context and question: Many, if not most, birds migrate in flocks. For larger birds, flying in flocks reduces the energy cost. Geese in a V-formation may conserve 1220% of the energy they would need to fly alone. Red knots Calidris canutus and dunlins Calidris alpina were found in radar studies to fly 5 km/h (3.1 mph) faster in flocks than when they were flying alone.
How do birds conserve energy?
Answer: a V-formation

Problem: Miami:

In recent years the city government, under Mayor Manny Diaz, has taken an ambitious stance in support of bicycling in Miami for both recreation and commuting. Every month, the city hosts "Bike Miami", where major streets in Downtown and Brickell are closed to automobiles, but left open for pedestrians and bicyclists. The event began in November 2008, and has doubled in popularity from 1,500 participants to about 3,000 in the October 2009 Bike Miami. This is the longest-running such event in the US. In October 2009, the city also approved an extensive 20-year plan for bike routes and paths around the city. The city has begun construction of bike routes as of late 2009, and ordinances requiring bike parking in all future construction in the city became mandatory as of October 2009.

In what month in 2008 did Bike Miami start?
