Problem: Hellenistic period:

Hellenistic culture produced seats of learning throughout the Mediterranean. Hellenistic science differed from Greek science in at least two ways: first, it benefited from the cross-fertilization of Greek ideas with those that had developed in the larger Hellenistic world; secondly, to some extent, it was supported by royal patrons in the kingdoms founded by Alexander's successors. Especially important to Hellenistic science was the city of Alexandria in Egypt, which became a major center of scientific research in the 3rd century BC. Hellenistic scholars frequently employed the principles developed in earlier Greek thought: the application of mathematics and deliberate empirical research, in their scientific investigations.

What century did Alexandria become scientific research hub?

A: 3rd

Oppidan scholarships may also be awarded for consistently performing with distinction in School and external examinations. To gain an Oppidan Scholarship, a boy must have either three distinctions in a row or four throughout his career. Within the school, an Oppidan Scholar is entitled to use the letters OS after his name.
How many distinguishments does a student need for an Oppidan Scholarship?

In December 2009, then Indian Navy chief Admiral Nirmal Kumar Verma said at his maiden navy week press conference that concepts currently being examined by the Directorate of Naval Design for the second indigenous aircraft carrier (IAC-2), are for a conventionally powered carrier displacing over 50,000 tons and equipped with steam catapults (rather than the ski-jump on the Gorshkov/Vikramaditya and the IAC) to launch fourth-generation aircraft. Later on in August 2013 Vice Admiral RK Dhowan, while talking about the detailed study underway on the IAC-II project, said that nuclear propulsion was also being considered. The navy also evaluated the Electromagnetic Aircraft Launch System (EMALS), which is being used by the US Navy in their latest Gerald R. Ford-class aircraft carriers. General Atomics, the developer of the EMALS, was cleared by the US government to give a technical demonstration to Indian Navy officers, who were impressed by the new capabilities of the system. The EMALS enables launching varied aircraft including unmanned combat air vehicles (UCAV). The aim is to have a total of three aircraft carriers in service, with two fully operational carriers and the third in refit.
What does MEALS stand for?
A: unanswerable

Question: A squab is the name given to the young of domestic pigeons that are destined for the table. Like other domesticated pigeons, birds used for this purpose are descended from the rock pigeon (Columba livia). Special utility breeds with desirable characteristics are used. Two eggs are laid and incubated for about 17 days. When they hatch, the squabs are fed by both parents on "pigeon's milk", a thick secretion high in protein produced by the crop. Squabs grow rapidly, but are slow to fledge and are ready to leave the nest at 26 to 30 days weighing about 500 g (18 oz). By this time, the adult pigeons will have laid and be incubating another pair of eggs and a prolific pair should produce two squabs every four weeks during a breeding season lasting several months.
Is there an answer to this question: What variety of pigeon does the squab avoid?

Answer: unanswerable

The Greek word (Christianos), meaning "follower of Christ", comes from (Christos), meaning "anointed one", with an adjectival ending borrowed from Latin to denote adhering to, or even belonging to, as in slave ownership. In the Greek Septuagint, christos was used to translate the Hebrew (Masiah, messiah), meaning "[one who is] anointed." In other European languages, equivalent words to Christian are likewise derived from the Greek, such as Chretien in French and Cristiano in Spanish.
While Christos means follower of Christ, what does Christianos mean?
