Input: Article: Many other builds were released until the Japan's Developers Day conference, when Steven Sinofsky announced that Windows 8 Release Preview (build 8400) would be released during the first week of June. On May 28, 2012, Windows 8 Release Preview (Standard Simplified Chinese x64 edition, not China-specific version, build 8400) was leaked online on various Chinese and BitTorrent websites. On May 31, 2012, Windows 8 Release Preview was released to the public by Microsoft. Major items in the Release Preview included the addition of Sports, Travel, and News apps, along with an integrated version of Adobe Flash Player in Internet Explorer. Like the Developer Preview and the Consumer Preview, the release preview expired on January 15, 2013.

Now answer this question: What were the main components of the Release preview?

Output: addition of Sports, Travel, and News apps, along with an integrated version of Adobe Flash Player

Input: Article: Simultaneous with Israel's February raid, the Baghdad Pact was formed between some regional allies of the UK. Nasser considered the Baghdad Pact a threat to his efforts to eliminate British military influence in the Middle East, and a mechanism to undermine the Arab League and "perpetuate [Arab] subservience to Zionism and [Western] imperialism". Nasser felt that if he was to maintain Egypt's regional leadership position he needed to acquire modern weaponry to arm his military. When it became apparent to him that Western countries would not supply Egypt under acceptable financial and military terms, Nasser turned to the Eastern Bloc and concluded a US$320,000,000 armaments agreement with Czechoslovakia on 27 September. Through the Czechoslovakian arms deal, the balance of power between Egypt and Israel was more or less equalized and Nasser's role as the Arab leader defying the West was enhanced.

Now answer this question: How did the military relationship between Egypt and Israel change?

Output: equalized

Input: Article: A 2001 study by Nebel et al. showed that both Ashkenazi and Sephardic Jewish populations share the same overall paternal Near Eastern ancestries. In comparison with data available from other relevant populations in the region, Jews were found to be more closely related to groups in the north of the Fertile Crescent. The authors also report on Eu 19 (R1a) chromosomes, which are very frequent in Central and Eastern Europeans (54%60%) at elevated frequency (12.7%) in Ashkenazi Jews. They hypothesized that the differences among Ashkenazim Jews could reflect low-level gene flow from surrounding European populations and/or genetic drift during isolation. A later 2005 study by Nebel et al., found a similar level of 11.5% of male Ashkenazim belonging to R1a1a (M17+), the dominant Y-chromosome haplogroup in Central and Eastern Europeans.

Now answer this question: Levels of the Eu 19 (R1a) chromosome are typically seen between what two percentages in Central and Eastern Europeans?

Output:
54%60%
