QUES: Evidence suggests that blast furnaces, that convert raw iron ore into pig iron, which can be remelted in a cupola furnace to produce cast iron by means of a cold blast and hot blast, were operational in China by the late Spring and Autumn period (722481 BC). The bloomery was nonexistent in ancient China; however, the Han-era Chinese produced wrought iron by injecting excess oxygen into a furnace and causing decarburization. Cast iron and pig iron could be converted into wrought iron and steel using a fining process.
What element was used in the production of wrought iron?

ANS: oxygen

QUES: Monotheists hold that there is only one god, and may claim that the one true god is worshiped in different religions under different names. The view that all theists actually worship the same god, whether they know it or not, is especially emphasized in Hinduism and Sikhism. In Christianity, the doctrine of the Trinity describes God as one God in three persons. The Trinity comprises God the Father, God the Son (Jesus), and God the Holy Spirit. Islam's most fundamental concept is tawhid (meaning "oneness" or "uniqueness"). God is described in the Quran as: "Say: He is Allah, the One and Only; Allah, the Eternal, Absolute; He begetteth not, nor is He begotten; And there is none like unto Him." Muslims repudiate the Christian doctrine of the Trinity and divinity of Jesus, comparing it to polytheism. In Islam, God is beyond all comprehension or equal and does not resemble any of his creations in any way. Thus, Muslims are not iconodules, and are not expected to visualize God.
What is the most basic belief of the Muslim religion?

ANS:
tawhid
