Problem: States of Germany:

Upon its founding in 1949, West Germany had eleven states. These were reduced to nine in 1952 when three south-western states (South Baden, Württemberg-Hohenzollern, and Württemberg-Baden) merged to form Baden-Württemberg. From 1957, when the French-occupied Saar Protectorate was returned and formed into the Saarland, the Federal Republic consisted of ten states, which are referred to as the "Old States" today. West Berlin was under the sovereignty of the Western Allies and neither a Western German state nor part of one. However, it was in many ways de facto integrated with West Germany under a special status.

What are referred to as the 'new states'?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Richmond emerged a decade after the smoldering rubble of the Civil War to resume its position as an economic powerhouse, with iron front buildings and massive brick factories. Canal traffic peaked in the 1860s and slowly gave way to railroads, allowing Richmond to become a major railroad crossroads, eventually including the site of the world's first triple railroad crossing. Tobacco warehousing and processing continued to play a role, boosted by the world's first cigarette-rolling machine, invented by James Albert Bonsack of Roanoke in 1880/81. Contributing to Richmond's resurgence was the first successful electrically powered trolley system in the United States, the Richmond Union Passenger Railway. Designed by electric power pioneer Frank J. Sprague, the trolley system opened its first line in 1888, and electric streetcar lines rapidly spread to other cities across the country. Sprague's system used an overhead wire and trolley pole to collect current, with electric motors on the car's trucks. In Richmond, the transition from streetcars to buses began in May 1947 and was completed on November 25, 1949.
What sort of railroad crossing was first built at Richmond?
A: triple

Problem: Hunting:

Since 1934, the sale of Federal Duck Stamps has generated $670 million, and helped to purchase or lease 5,200,000 acres (8,100 sq mi; 21,000 km2) of habitat. The stamps serve as a license to hunt migratory birds, an entrance pass for all National Wildlife Refuge areas, and are also considered collectors items often purchased for aesthetic reasons outside of the hunting and birding communities. Although non-hunters buy a significant number of Duck Stamps, eighty-seven percent of their sales are contributed by hunters, which is logical, as hunters are required to purchase them. Distribution of funds is managed by the Migratory Bird Conservation Commission (MBCC).

How many acres has the sale of Federal Duck Stamps helped to purchase or lease since 1934?
---
A:
5,200,000 acres
