Problem: Windows 8:

Windows 8 supports a feature of the UEFI specification known as "Secure boot", which uses a public-key infrastructure to verify the integrity of the operating system and prevent unauthorized programs such as bootkits from infecting the device's boot process. Some pre-built devices may be described as "certified" by Microsoft; these must have secure boot enabled by default, and provide ways for users to disable or re-configure the feature. ARM-based Windows RT devices must have secure boot permanently enabled.

How does insecure boot help avert boot process infections?

Problem: London is the world's most expensive office market for the last three years according to world property journal (2015) report. As of 2015[update] the residential property in London is worth $2.2 trillion - same value as that of Brazil annual GDP. The city has the highest property prices of any European city according to the Office for National Statistics and the European Office of Statistics. On average the price per square metre in central London is €24,252 (April 2014). This is higher than the property prices in other G8 European capital cities; Berlin €3,306, Rome €6,188 and Paris €11,229.
A World Property Journal report has ranked London as the most expensive office market in the world for how many consecutive years?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Early human genetic cluster analysis studies were conducted with samples taken from ancestral population groups living at extreme geographic distances from each other. It was thought that such large geographic distances would maximize the genetic variation between the groups sampled in the analysis and thus maximize the probability of finding cluster patterns unique to each group. In light of the historically recent acceleration of human migration (and correspondingly, human gene flow) on a global scale, further studies were conducted to judge the degree to which genetic cluster analysis can pattern ancestrally identified groups as well as geographically separated groups. One such study looked at a large multiethnic population in the United States, and "detected only modest genetic differentiation between different current geographic locales within each race/ethnicity group. Thus, ancient geographic ancestry, which is highly correlated with self-identified race/ethnicity—as opposed to current residence—is the major determinant of genetic structure in the U.S. population." (Tang et al. (2005))
Human migration tends to accelerate this type of what flow?
A: gene


Context and question: Basic sanitation techniques can have a profound effect on the transmission of diarrheal disease. The implementation of hand washing using soap and water, for example, has been experimentally shown to reduce the incidence of disease by approximately 42–48%. Hand washing in developing countries, however, is compromised by poverty as acknowledged by the CDC: "Handwashing is integral to disease prevention in all parts of the world; however, access to soap and water is limited in a number of less developed countries. This lack of access is one of many challenges to proper hygiene in less developed countries." Solutions to this barrier require the implementation of educational programs that encourage sanitary behaviours.
What is a challenge to reduce disease in less developed countries?
Answer: unanswerable


Question: In the past, Qutb Shahi rulers and Nizams attracted artists, architects and men of letters from different parts of the world through patronage. The resulting ethnic mix popularised cultural events such as mushairas (poetic symposia). The Qutb Shahi dynasty particularly encouraged the growth of Deccani Urdu literature leading to works such as the Deccani Masnavi and Diwan poetry, which are among the earliest available manuscripts in Urdu. Lazzat Un Nisa, a book compiled in the 15th century at Qutb Shahi courts, contains erotic paintings with diagrams for secret medicines and stimulants in the eastern form of ancient sexual arts. The reign of the Nizams saw many literary reforms and the introduction of Urdu as a language of court, administration and education. In 1824, a collection of Urdu Ghazal poetry, named Gulzar-e-Mahlaqa, authored by Mah Laqa Bai—the first female Urdu poet to produce a Diwan—was published in Hyderabad.
Is there an answer to this question: When was Lazzat Un Nisa completed?

Answer: the 15th century


Question: Media files are stored on an iPod in a hidden folder, along with a proprietary database file. The hidden content can be accessed on the host operating system by enabling hidden files to be shown. The media files can then be recovered manually by copying the files or folders off the iPod. Many third-party applications also allow easy copying of media files off of an iPod.
Is there an answer to this question: In what kind of folder are files located in the iPod?

Answer:
hidden
