QUES: In Hellenistic Egypt, the mathematician Euclid laid down the foundations of mathematical rigor and introduced the concepts of definition, axiom, theorem and proof still in use today in his Elements, considered the most influential textbook ever written. Archimedes, considered one of the greatest mathematicians of all time, is credited with using the method of exhaustion to calculate the area under the arc of a parabola with the summation of an infinite series, and gave a remarkably accurate approximation of Pi. He is also known in physics for laying the foundations of hydrostatics, statics, and the explanation of the principle of the lever.
Which mathematical figure did Archimedes approximate?

ANS: Pi

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.
What do Macs lack that makes them able to run many legacy PC operating systems?

ANS: unanswerable

QUES: Others have rejected that the doctrine of Immaculate Conception exists in Islam, the Quranic account does not confirm the Immaculate Conception exclusively for Mary as in Islam every human child is born pure and immaculate, her sinless birth is thus independent of the Christian docrtrine of original sin as no such doctrine exists in Islam. Moreover, Hannah's prayer in the Quran for her child to remain protected from Satan (Shaytan) was said after it had already been born, not before and expresses a natural concern any righteous parent would have. The Muslim tradition or hadith, which states that the only children born without the "touch of Satan," were Mary and Jesus. should therefore not be taken in isolation from the Quran, and is to be interpreted within the specific context of exonerating Mary and her child from the charges that were made against them and is not a general statement. The specific mention of Mary and Jesus in this hadith may also be taken to represent a class of people, in keeping with the Arabic language and the Quranic verse [O Satan] surely thou shalt have no power over My servants, except such of the erring ones as choose to follow thee (15:42)
Does this view contradict the belief that Mary was also born to a virgin mother ?

ANS: her sinless birth is thus independent of the Christian docrtrine of original sin as no such doctrine exists in Islam

QUES: Soon after the war began, General MacArthur had begun planning a landing at Incheon, but the Pentagon opposed him. When authorized, he activated a combined U.S. Army and Marine Corps, and ROK Army force. The X Corps, led by General Edward Almond, Commander, consisted of 40,000 men of the 1st Marine Division, the 7th Infantry Division and around 8,600 ROK Army soldiers. By 15 September, the amphibious assault force faced few KPA defenders at Incheon: military intelligence, psychological warfare, guerrilla reconnaissance, and protracted bombardment facilitated a relatively light battle. However, the bombardment destroyed most of the city of Incheon.
What Corps included 40,000 men from the 1st Marine Division?

ANS:
The X Corps
