QUES: As of 2015[update], Nigeria is the world's 20th largest economy, worth more than $500 billion and $1 trillion in terms of nominal GDP and purchasing power parity respectively. It overtook South Africa to become Africa's largest economy in 2014. Also, the debt-to-GDP ratio is only 11 percent, which is 8 percent below the 2012 ratio. Nigeria is considered to be an emerging market by the World Bank; It has been identified as a regional power on the African continent, a middle power in international affairs, and has also been identified as an emerging global power. Nigeria is a member of the MINT group of countries, which are widely seen as the globe's next "BRIC-like" economies.

QUES: Glass has the ability to refract, reflect, and transmit light following geometrical optics, without scattering it. It is used in the manufacture of lenses and windows. Common glass has a refraction index around 1.5. This may be modified by adding low-density materials such as boron, which lowers the index of refraction (see crown glass), or increased (to as much as 1.8) with high-density materials such as (classically) lead oxide (see flint glass and lead glass), or in modern uses, less toxic oxides of zirconium, titanium, or barium. These high-index glasses (inaccurately known as "crystal" when used in glass vessels) cause more chromatic dispersion of light, and are prized for their diamond-like optical properties.
Why are high-index glasses valued?

ANS: for their diamond-like optical properties

QUES: With preceding legal institutions abolished, Gaddafi envisioned the Jamahiriya as following the Qur'an for legal guidance, adopting sharia law; he proclaimed "man-made" laws unnatural and dictatorial, only permitting Allah's law. Within a year he was backtracking, announcing that sharia was inappropriate for the Jamahiriya because it guaranteed the protection of private property, contravening The Green Book's socialism. His emphasis on placing his own work on a par with the Qur'an led conservative clerics to accuse him of shirk, furthering their opposition to his regime. In July, a border war broke out with Egypt, in which the Egyptians defeated Libya despite their technological inferiority. The conflict lasted one week before both sides agreed to sign a peace treaty that was brokered by several Arab states. That year, Gaddafi was invited to Moscow by the Soviet government in recognition of their increasing commercial relationship.
What book did the Jamahiriya look to for legal advice?

ANS:
Qur'an
