PROBLEM: The original model Famicom featured two game controllers, both of which were hardwired to the back of the console. The second controller lacked the START and SELECT buttons, but featured a small microphone. Relatively few games made use of this feature. The earliest produced Famicom units initially had square A and B buttons. This was changed to the circular designs because of the square buttons being caught in the controller casing when pressed down and glitches within the hardware causing the system to freeze occasionally while playing a game.

SOLUTION: How were the Famicom controllers attached to the console?

PROBLEM: After 1870, the new railroads across the Plains brought hunters who killed off almost all the bison for their hides. The railroads offered attractive packages of land and transportation to European farmers, who rushed to settle the land. They (and Americans as well) also took advantage of the homestead laws to obtain free farms. Land speculators and local boosters identified many potential towns, and those reached by the railroad had a chance, while the others became ghost towns. In Kansas, for example, nearly 5000 towns were mapped out, but by 1970 only 617 were actually operating. In the mid-20th century, closeness to an interstate exchange determined whether a town would flourish or struggle for business.

SOLUTION: after about what year did railroads bring hunters to the great plains?

PROBLEM: Cardigan formed up his unit and charged the length of the Valley of the Balaclava, under fire from Russian batteries in the hills. The charge of the Light Brigade caused 278 casualties of the 700-man unit. The Light Brigade was memorialized in the famous poem by Alfred Lord Tennyson, "The Charge of the Light Brigade." Although traditionally the charge of the Light Brigade was looked upon as a glorious but wasted sacrifice of good men and horses, recent historians say that the charge of the Light Brigade did succeed in at least some of its objectives. The aim of any cavalry charge is to scatter the enemy lines and frighten the enemy off the battlefield. The charge of the Light Brigade had so unnerved the Russian cavalry, which had previously been routed by the Heavy Brigade, that the Russian Cavalry was set to full-scale flight by the subsequent charge of the Light Brigade.:252

SOLUTION:
Who led the charge on the Valley of Balaclava?
