Question: Evaporation and sublimation into a vacuum is called outgassing. All materials, solid or liquid, have a small vapour pressure, and their outgassing becomes important when the vacuum pressure falls below this vapour pressure. In man-made systems, outgassing has the same effect as a leak and can limit the achievable vacuum. Outgassing products may condense on nearby colder surfaces, which can be troublesome if they obscure optical instruments or react with other materials. This is of great concern to space missions, where an obscured telescope or solar cell can ruin an expensive mission.

Question: YouTube does not usually offer a download link for its videos, and intends for them to be viewed through its website interface. A small number of videos, such as the weekly addresses by President Barack Obama, can be downloaded as MP4 files. Numerous third-party web sites, applications and browser plug-ins allow users to download YouTube videos. In February 2009, YouTube announced a test service, allowing some partners to offer video downloads for free or for a fee paid through Google Checkout. In June 2012, Google sent cease and desist letters threatening legal action against several websites offering online download and conversion of YouTube videos. In response, Zamzar removed the ability to download YouTube videos from its site. The default settings when uploading a video to YouTube will retain a copyright on the video for the uploader, but since July 2012 it has been possible to select a Creative Commons license as the default, allowing other users to reuse and remix the material if it is free of copyright.

Question: Greece was accused of trying to cover up the extent of its massive budget deficit in the wake of the global financial crisis. The allegation was prompted by the massive revision of the 2009 budget deficit forecast by the new PASOK government elected in October 2009, from "68%" (estimated by the previous New Democracy government) to 12.7% (later revised to 15.7%). However, the accuracy of the revised figures has also been questioned, and in February 2012 the Hellenic Parliament voted in favor of an official investigation following accusations by a former member of the Hellenic Statistical Authority that the deficit had been artificially inflated in order to justify harsher austerity measures.
Is there an answer to this question: When did the Parliament vote in favor of an investigation?

Answer:
February 2012
