QUES: She is the only woman directly named in the Qur'an; declared (uniquely along with Jesus) to be a Sign of God to humanity; as one who "guarded her chastity"; an obedient one; chosen of her mother and dedicated to Allah whilst still in the womb; uniquely (amongst women) Accepted into service by God; cared for by (one of the prophets as per Islam) Zakariya (Zacharias); that in her childhood she resided in the Temple and uniquely had access to Al-Mihrab (understood to be the Holy of Holies), and was provided with heavenly "provisions" by God.
Who dedicated Mary to Allah while she still in her mother's womb?

ANS: unanswerable

QUES: The first successful light bulb filaments were made of carbon (from carbonized paper or bamboo). Early carbon filaments had a negative temperature coefficient of resistance — as they got hotter, their electrical resistance decreased. This made the lamp sensitive to fluctuations in the power supply, since a small increase of voltage would cause the filament to heat up, reducing its resistance and causing it to draw even more power and heat even further. In the "flashing" process, carbon filaments were heated by current passing through them while in an evacuated vessel containing hydrocarbon vapor (usually gasoline). The carbon deposited on the filament by this treatment improved the uniformity and strength of filaments as well as their efficiency. A metallized or "graphitized" filament was first heated in a high-temperature oven before flashing and lamp assembly. This transformed the carbon into graphite which further strengthened and smoothed the filament. This also changed the filament to have a positive temperature coefficient, like a metallic conductor, and helped stabilize the lamp's power consumption, temperature and light output against minor variations in supply voltage.
What were the positive effects of the flashing process?

ANS: improved the uniformity and strength of filaments as well as their efficiency

QUES: After a period of confusion following Alexander's death, the Antigonid dynasty, descended from one of Alexander's generals, established its control over Macedon and most of the Greek city-states by 276 BC. From about 200 BC the Roman Republic became increasingly involved in Greek affairs and engaged in a series of wars with Macedon. Macedon's defeat at the Battle of Pydna in 168 BC signalled the end of Antigonid power in Greece. In 146 BC Macedonia was annexed as a province by Rome, and the rest of Greece became a Roman protectorate.
Who controlled Macedon after Alexander died?

ANS: the Antigonid dynasty

QUES: The Hanoverian king George II of Great Britain was passionately devoted to his family’s continental holdings, but his commitments in Germany were counterbalanced by the demands of the British colonies overseas. If war against France for colonial expansion was to be resumed, then Hanover had to be secured against Franco-Prussian attack. France was very much interested in colonial expansion and was willing to exploit the vulnerability of Hanover in war against Great Britain, but it had no desire to divert forces to central Europe for Prussia's interest.
How anxious was France to assist Prussia to take over Hanover?

ANS:
it had no desire to divert forces to central Europe for Prussia's interest.
