Question: Windows 8 introduced major changes to the operating system's platform and user interface to improve its user experience on tablets, where Windows was now competing with mobile operating systems, including Android and iOS. In particular, these changes included a touch-optimized Windows shell based on Microsoft's "Metro" design language, the Start screen (which displays programs and dynamically updated content on a grid of tiles), a new platform for developing apps with an emphasis on touchscreen input, integration with online services (including the ability to sync apps and settings between devices), and Windows Store, an online store for downloading and purchasing new software. Windows 8 added support for USB 3.0, Advanced Format hard drives, near field communications, and cloud computing. Additional security features were introduced, such as built-in antivirus software, integration with Microsoft SmartScreen phishing filtering service and support for UEFI Secure Boot on supported devices with UEFI firmware, to prevent malware from infecting the boot process.

Question: The old oracles in Delphi seem to be connected with a local tradition of the priesthood, and there is not clear evidence that a kind of inspiration-prophecy existed in the temple. This led some scholars to the conclusion that Pythia carried on the rituals in a consistent procedure through many centuries, according to the local tradition. In that regard, the mythical seeress Sibyl of Anatolian origin, with her ecstatic art, looks unrelated to the oracle itself. However, the Greek tradition is referring to the existence of vapours and chewing of laurel-leaves, which seem to be confirmed by recent studies.
Try to answer this question if possible: What Greek tradition seems to be confirmed by recent studies?
Answer: existence of vapours and chewing of laurel-leaves
Question: 
 China: In China, the torch was first welcomed by Politburo Standing Committee member Zhou Yongkang and State Councilor Liu Yandong. It was subsequently passed onto CPC General Secretary Hu Jintao. A call to boycott French hypermart Carrefour from May 1 began spreading through mobile text messaging and online chat rooms amongst the Chinese over the weekend from April 12, accusing the company's major shareholder, the LVMH Group, of donating funds to the Dalai Lama. There were also calls to extend the boycott to include French luxury goods and cosmetic products. According to the Washington Times on April 15, however, the Chinese government was attempting to "calm the situation" through censorship: "All comments posted on popular Internet forum Sohu.com relating to a boycott of Carrefour have been deleted." Chinese protesters organized boycotts of the French-owned retail chain Carrefour in major Chinese cities including Kunming, Hefei and Wuhan, accusing the French nation of pro-secessionist conspiracy and anti-Chinese racism. Some burned French flags, some added Nazism's Swastika to the French flag, and spread short online messages calling for large protests in front of French consulates and embassy. The Carrefour boycott was met with anti-boycott demonstrators who insisted on entering one of the Carrefour stores in Kunming, only to be blocked by boycotters wielding large Chinese flags and hit by water bottles. The BBC reported that hundreds of people demonstrated in Beijing, Wuhan, Hefei, Kunming and Qingdao.
