QUES: Following the release of Intel-based Macs, third-party platform virtualization software such as Parallels Desktop, VMware Fusion, and VirtualBox began to emerge. These programs allow users to run Microsoft Windows or previously Windows-only software on Macs at near native speed. Apple also released Boot Camp and Mac-specific Windows drivers that help users to install Windows XP or Vista and natively dual boot between Mac OS X and Windows. Though not condoned by Apple, it is possible to run the Linux operating system using Boot camp or other virtualization workarounds. Unlike most PCs, however, Macs are unable to run many legacy PC operating systems. In particular, Intel-based macs lack the A20 gate.
At what speed do programs such as VirtualBox allow Microsoft Windows to run on Macs?

ANS: at near native speed

QUES: Drug discovery and development is very expensive; of all compounds investigated for use in humans only a small fraction are eventually approved in most nations by government appointed medical institutions or boards, who have to approve new drugs before they can be marketed in those countries. In 2010 18 NMEs (New Molecular Entities) were approved and three biologics by the FDA, or 21 in total, which is down from 26 in 2009 and 24 in 2008. On the other hand, there were only 18 approvals in total in 2007 and 22 back in 2006. Since 2001, the Center for Drug Evaluation and Research has averaged 22.9 approvals a year. This approval comes only after heavy investment in pre-clinical development and clinical trials, as well as a commitment to ongoing safety monitoring. Drugs which fail part-way through this process often incur large costs, while generating no revenue in return. If the cost of these failed drugs is taken into account, the cost of developing a successful new drug (new chemical entity, or NCE), has been estimated at about 1.3 billion USD(not including marketing expenses). Professors Light and Lexchin reported in 2012, however, that the rate of approval for new drugs has been a relatively stable average rate of 15 to 25 for decades.
Who is responsible for approval or rejection of new drugs?

ANS: Center for Drug Evaluation and Research

QUES: Homer uses the terms Achaeans and Danaans () as a generic term for Greeks in Iliad, and they were probably a part of the Mycenean civilization. The names Achaioi and Danaoi seem to be pre-Dorian belonging to the people who were overthrown. They were forced to the region that later bore the name Achaea after the Dorian invasion. In the 5th century BC, they were redefined as contemporary speakers of Aeolic Greek which was spoken mainly in Thessaly, Boeotia and Lesbos. There are many controversial theories on the origin of the Achaeans. According to one view, the Achaeans were one of the fair-headed tribes of upper Europe, who pressed down over the Alps during the early Iron age (1300 BC) to southern Europe. Another theory suggests that the Peloponnesian Dorians were the Achaeans. These theories are rejected by other scholars who, based on linguistic criteria, suggest that the Achaeans were mainland pre-Dorian Greeks. There is also the theory that there was an Achaean ethnos that migrated from Asia minor to lower Thessaly prior to 2000 BC. Some Hittite texts mention a nation lying to the west called Ahhiyava or Ahhiya. Egyptian documents refer to Ekwesh, one of the groups of sea peoples who attached Egypt during the reign of Merneptah (1213-1203 BCE), who may have been Achaeans.
What was the age in 1300 BC named ?

ANS: early Iron age

QUES: Apart from residences for upper and middle class households, sanitation is insufficient in most residential areas. Private flush toilets are too expensive for virtually all residents in townships due to their water consumption and installation cost. As a result, access to improved sanitation has not increased much since independence: In Namibia's rural areas 13% of the population had more than basic sanitation, up from 8% in 1990. Many of Namibia's inhabitants have to resort to "flying toilets", plastic bags to defecate which after use are flung into the bush. The use of open areas close to residential land to urinate and defecate is very common and has been identified as a major health hazard.
Urinating and defecating in public has been identified as what?

ANS:
major health hazard
