Here is a question about this article: In December 2005, Imperial announced a science park programme at the Wye campus, with extensive housing; however, this was abandoned in September 2006 following complaints that the proposal infringed on Areas of Outstanding Natural Beauty, and that the true scale of the scheme, which could have raised 110m for the College, was known to Kent and Ashford Councils and their consultants but concealed from the public. One commentator observed that Imperial's scheme reflected "the state of democracy in Kent, the transformation of a renowned scientific college into a grasping, highly aggressive, neo-corporate institution, and the defence of the status of an Area of Outstanding Natural Beauty throughout England, not just Wye against rampant greed backed by the connivance of two important local authorities. Wye College campus was finally closed in September 2009.
What is the answer to this question: What was closed on September 2009?

So... Wye College campus

Here is a question about this article: On July 1, 1985, Gorbachev promoted Eduard Shevardnadze, First Secretary of the Georgian Communist Party, to full member of the Politburo, and the following day appointed him minister of foreign affairs, replacing longtime Foreign Minister Andrei Gromyko. The latter, disparaged as "Mr Nyet" in the West, had served for 28 years as Minister of Foreign Affairs. Gromyko was relegated to the largely ceremonial position of Chairman of the Presidium of the Supreme Soviet (officially Soviet Head of State), as he was considered an "old thinker." Also on July 1, Gorbachev took the opportunity to dispose of his main rival by removing Grigory Romanov from the Politburo, and brought Boris Yeltsin and Lev Zaikov into the CPSU Central Committee Secretariat.
What is the answer to this question: What was Gromyko's western nickname?

So... "Mr Nyet"

Here is a question about this article: Since 1996, they have been archiving cached pages of web sites onto their large cluster of Linux nodes. They revisit sites every few weeks or months and archive a new version if the content has changed. Sites can also be captured on the fly by visitors who are offered a link to do so. The intent is to capture and archive content that otherwise would be lost whenever a site is changed or closed down. Their grand vision is to archive the entire Internet.
What is the answer to this question: When does Wayback Machine save a copy of a website?
