Problem: United States Army:

By 1989 Germany was nearing reunification and the Cold War was coming to a close. Army leadership reacted by starting to plan for a reduction in strength. By November 1989 Pentagon briefers were laying out plans to reduce army end strength by 23%, from 750,000 to 580,000. A number of incentives such as early retirement were used. In 1990 Iraq invaded its smaller neighbor, Kuwait, and U.S. land forces, quickly deployed to assure the protection of Saudi Arabia. In January 1991 Operation Desert Storm commenced, a U.S.-led coalition which deployed over 500,000 troops, the bulk of them from U.S. Army formations, to drive out Iraqi forces. The campaign ended in total victory, as Western coalition forces routed the Iraqi Army, organized along Soviet lines, in just one hundred hours.

Problem: Super Nintendo Entertainment System:

Japan saw the release of the Satellaview, a modem which attached to the Super Famicom's expansion port and connected to the St.GIGA satellite radio station. Users of the Satellaview could download gaming news and specially designed games, which were frequently either remakes of or sequels to older Famicom titles, released in installments. Satellaview signals were broadcast from April 23, 1995 through June 30, 2000. In the United States, the similar but relatively short-lived XBAND allowed users to connect to a network via a dial-up modem to compete against other players around the country.

When did the Satellaview end operation?
---
A: June 30, 2000

Problem: Biodiversity:

A 2007 study conducted by the National Science Foundation found that biodiversity and genetic diversity are codependentthat diversity among species requires diversity within a species, and vice versa. "If any one type is removed from the system, the cycle can break down, and the community becomes dominated by a single species." At present, the most threatened ecosystems are found in fresh water, according to the Millennium Ecosystem Assessment 2005, which was confirmed by the "Freshwater Animal Diversity Assessment", organised by the biodiversity platform, and the French Institut de recherche pour le developpement (MNHNP).

Who conducted the 2000 study?
