Most of the differences in the revised budget deficit numbers were due to a temporary change of accounting practices by the new government, i.e., recording expenses when military material was ordered rather than received. However, it was the retroactive application of ESA95 methodology (applied since 2000) by Eurostat, that finally raised the reference year (1999) budget deficit to 3.38% of GDP, thus exceeding the 3% limit. This led to claims that Greece (similar claims have been made about other European countries like Italy) had not actually met all five accession criteria, and the common perception that Greece entered the Eurozone through "falsified" deficit numbers.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): When were expenses classified by the new government?
Ah, so.. unanswerable

About 20% of pupils at Eton receive financial support, through a range of bursaries and scholarships. The recent Head Master, Tony Little, said that Eton is developing plans to allow any boy to attend the school whatever his parents' income and, in 2011, said that around 250 boys received "significant" financial help from the school. In early 2014, this figure had risen to 263 pupils receiving the equivalent of around 60% of school fee assistance, whilst a further 63 received their education free of charge. Little said that, in the short term, he wanted to ensure that around 320 pupils per year receive bursaries, and that 70 were educated free of charge, with the intention that the number of pupils receiving financial assistance would continue to increase. These comparatively new developments will run alongside long-established courses that Eton has provided for pupils from state schools, most of them in the summer holidays (July and August). Launched in 1982, the Universities Summer School is an intensive residential course open to boys and girls throughout the UK who attend state schools, are at the end of their first year in the Sixth Form, and are about to begin their final year of schooling. The Brent-Eton Summer School, started in 1994, offers 40-50 young people from the London Borough of Brent, an area of inner-city deprivation, an intensive one-week residential course, free of charge, designed to help bridge the gap between GCSE and A-level. In 2008, Eton helped found the Eton, Slough, Windsor and Hounslow Independent and State School Partnership (ISSP), with six local state schools. The ISSP's aims are "to raise pupil achievement, improve pupil self-esteem, raise pupil aspirations and improve professional practice across the schools". Eton also runs a number of choral and English language courses during the summer months.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many students attended Eton free of charge in 2014?
Ah, so.. 63

In March 2011, it was said on the Wayback Machine forum that "The Beta of the new Wayback Machine has a more complete and up-to-date index of all crawled materials into 2010, and will continue to be updated regularly. The index driving the classic Wayback Machine only has a little bit of material past 2008, and no further index updates are planned, as it will be phased out this year".
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): The older version of Wayback Machine did not have much new data past what year?
Ah, so..
