The problem: Answer a question about this article:
The presence of the Virgin Mary under the cross[Jn. 19:26-27] has in itself been the subject of Marian art, and well known Catholic symbolism such as the Miraculous Medal and Pope John Paul II's Coat of Arms bearing a Marian Cross. And a number of Marian devotions also involve the presence of the Virgin Mary in Calvary, e.g., Pope John Paul II stated that "Mary was united to Jesus on the Cross". Well known works of Christian art by masters such as Raphael (e.g., the Mond Crucifixion), and Caravaggio (e.g., his Entombment) depict the Virgin Mary as part of the crucifixion scene.
What symbol is popular in Marian Art?
****
The answer: Marian Cross


The problem: Answer a question about this article:
While the Philippines is generally considered a civil law nation, its Supreme Court is heavily modelled after the American Supreme Court. This can be attributed to the fact that the Philippines was colonized by both Spain and the United States, and the system of laws of both nations strongly influenced the development of Philippine laws and jurisprudence. Even as the body of Philippine laws remain mostly codified, the Philippine Civil Code expressly recognizes that decisions of the Supreme Court "form part of the law of the land", belonging to the same class as statutes. The 1987 Philippine Constitution also explicitly grants to the Supreme Court the power of judicial review over laws and executive actions. The Supreme Court is composed of 1 Chief Justice and 14 Associate Justices. The court sits either en banc or in divisions, depending on the nature of the case to be decided.
What document grants the Philippines Supreme Court the right of judicial review?
****
The answer: 1987 Philippine Constitution


The problem: Answer a question about this article:
The earliest evidence of the presence of human ancestors in the southern Balkans, dated to 270,000 BC, is to be found in the Petralona cave, in the Greek province of Macedonia. All three stages of the stone age (Paleolithic, Mesolithic, and Neolithic) are represented in Greece, for example in the Franchthi Cave. Neolithic settlements in Greece, dating from the 7th millennium BC, are the oldest in Europe by several centuries, as Greece lies on the route via which farming spread from the Near East to Europe.
Humans in the Balkans have been dated to what year?
****
The answer: 270,000 BC


The problem: Answer a question about this article:
The alkali metal ions are small and mobile; their presence in glass allows a degree of electrical conductivity, especially in molten state or at high temperature. Their mobility decreases the chemical resistance of the glass, allowing leaching by water and facilitating corrosion. Alkaline earth ions, with their two positive charges and requirement for two non-bridging oxygen ions to compensate for their charge, are much less mobile themselves and also hinder diffusion of other ions, especially the alkalis. The most common commercial glasses contain both alkali and alkaline earth ions (usually sodium and calcium), for easier processing and satisfying corrosion resistance. Corrosion resistance of glass can be achieved by dealkalization, removal of the alkali ions from the glass surface by reaction with e.g. sulfur or fluorine compounds. Presence of alkaline metal ions has also detrimental effect to the loss tangent of the glass, and to its electrical resistance; glasses for electronics (sealing, vacuum tubes, lamps...) have to take this in account.
What can alkaline ions in glass harm, in addition to electrical resistance?
****
The answer:
loss tangent
