Problem: Avicenna:

Avicenna's consideration of the essence-attributes question may be elucidated in terms of his ontological analysis of the modalities of being; namely impossibility, contingency, and necessity. Avicenna argued that the impossible being is that which cannot exist, while the contingent in itself (mumkin bi-dhatihi) has the potentiality to be or not to be without entailing a contradiction. When actualized, the contingent becomes a 'necessary existent due to what is other than itself' (wajib al-wujud bi-ghayrihi). Thus, contingency-in-itself is potential beingness that could eventually be actualized by an external cause other than itself. The metaphysical structures of necessity and contingency are different. Necessary being due to itself (wajib al-wujud bi-dhatihi) is true in itself, while the contingent being is 'false in itself' and 'true due to something else other than itself'. The necessary is the source of its own being without borrowed existence. It is what always exists.

What is one modality of being that Avicenna analyzed?

A: necessity

Problem: Light-emitting diode:

An LED filament consists of multiple LED dice connected in series on a common longitudinal substrate that form a thin rod reminiscent of a traditional incandescent filament. These are being used as a low cost decorative alternative for traditional light bulbs that are being phased out in many countries. The filaments require a rather high voltage to light to nominal brightness, allowing them to work efficiently and simply with mains voltages. Often a simple rectifier and capacitive current limiting are employed to create a low-cost replacement for a traditional light bulb without the complexity of creating a low voltage, high current converter which is required by single die LEDs. Usually they are packaged in a sealed enclosure with a shape similar to lamps they were designed to replace (e.g. a bulb), and filled with inert nitrogen or carbon dioxide gas to remove heat efficiently.

What helps LED filaments remain low cost?
---
A: a simple rectifier

Problem: Bermuda:

Bermuda has developed a proud Rugby Union community. The Bermuda Rugby Union team won the 2011 Caribbean championships, defeating Guyana in the final. They previously beat The Bahamas and Mexico to take the crown. Rugby 7's is also played, with four rounds scheduled to take place in the 20112012 season. The Bermuda 7's team competed in the 2011 Las Vegas 7's, defeating the Mexican team. There are four clubs on the island: (1) Police (2) Mariners (3) Teachers (4) Renegades. There is a men's and women's competitioncurrent league champions are Police (Men) (winning the title for the first time since the 1990s) and Renegades (women's). Games are currently played at Warwick Academy. Bermuda u/19 team won the 2010 Caribbean Championships.

What did the Bermuda u/19 team win?
---
A: 2010 Caribbean Championships

Problem: Hellenistic period:

Roman entanglement in the Balkans began when Illyrian piratical raids on Roman merchants led to invasions of Illyria (the First and, Second Illyrian Wars). Tension between Macedon and Rome increased when the young king of Macedon, Philip V harbored one of the chief pirates, Demetrius of Pharos (a former client of Rome). As a result, in an attempt to reduce Roman influence in the Balkans, Philip allied himself with Carthage after Hannibal had dealt the Romans a massive defeat at the Battle of Cannae (216 BC) during the Second Punic War. Forcing the Romans to fight on another front when they were at a nadir of manpower gained Philip the lasting enmity of the Romans; the only real result from the somewhat insubstantial First Macedonian War (215202 BC).

Hannibal defeated whom at the Battle of Cannae?
---
A:
the Romans
