Problem: A cappella:

Instruments have divided Christendom since their introduction into worship. They were considered a Catholic innovation, not widely practiced until the 18th century, and were opposed vigorously in worship by a number of Protestant Reformers, including Martin Luther (14831546), Ulrich Zwingli, John Calvin (15091564) and John Wesley (17031791). Alexander Campbell referred to the use of an instrument in worship as "a cow bell in a concert". In Sir Walter Scott's The Heart of Midlothian, the heroine, Jeanie Deans, a Scottish Presbyterian, writes to her father about the church situation she has found in England (bold added):

Problem: Architectural design competitions are used by an organisation that plans to build a new building or refurbish an existing building. They can be used for buildings, engineering work, structures, landscape design projects or public realm artworks. A competition typically asks for architects and/or designers to submit a design proposal in response to a given Brief. The winning design will then be selected by an independent jury panel of design professionals and client representatives. The independence of the jury is vital to the fair conduct of a competition.
What is necessary for the integrity of a design competition?
---
Answer: independence of the jury

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
While pursuing his PhD at Princeton, Feynman married his high school sweetheart, Arline Greenbaum (often misspelled "Arlene"), despite the knowledge that she was seriously ill with tuberculosisan incurable disease at the time. She died in 1945. In 1946, Feynman wrote a letter to her, expressing his deep love and heartbreak, that he kept for the rest of his life. ("Please excuse my not mailing this," the letter concluded, "but I don't know your new address.") This portion of Feynman's life was portrayed in the 1996 film Infinity, which featured Feynman's daughter, Michelle, in a cameo role.
In which year did his wife die?
A: 1945

Context and question: Two groups of invertebrates have notably complex brains: arthropods (insects, crustaceans, arachnids, and others), and cephalopods (octopuses, squids, and similar molluscs). The brains of arthropods and cephalopods arise from twin parallel nerve cords that extend through the body of the animal. Arthropods have a central brain with three divisions and large optical lobes behind each eye for visual processing. Cephalopods such as the octopus and squid have the largest brains of any invertebrates.
Which two groups of invertebrates have complex brains?
Answer: arthropods (insects, crustaceans, arachnids, and others), and cephalopods

Question: Protestantism also spread from the German lands into France, where the Protestants were nicknamed Huguenots. Calvin continued to take an interest in the French religious affairs from his base in Geneva. He regularly trained pastors to lead congregations there. Despite heavy persecution, the Reformed tradition made steady progress across large sections of the nation, appealing to people alienated by the obduracy and the complacency of the Catholic establishment. French Protestantism came to acquire a distinctly political character, made all the more obvious by the conversions of nobles during the 1550s. This established the preconditions for a series of conflicts, known as the French Wars of Religion. The civil wars gained impetus with the sudden death of Henry II of France in 1559. Atrocity and outrage became the defining characteristics of the time, illustrated at their most intense in the St. Bartholomew's Day massacre of August 1572, when the Roman Catholic party annihilated between 30,000 and 100,000 Huguenots across France. The wars only concluded when Henry IV of France issued the Edict of Nantes, promising official toleration of the Protestant minority, but under highly restricted conditions. Roman Catholicism remained the official state religion, and the fortunes of French Protestants gradually declined over the next century, culminating in Louis XIV's Edict of Fontainebleau which revoked the Edict of Nantes and made Roman Catholicism the sole legal religion once again. In response to the Edict of Fontainebleau, Frederick William I, Elector of Brandenburg declared the Edict of Potsdam, giving free passage to Huguenot refugees. In the late 17th century many Huguenots fled to England, the Netherlands, Prussia, Switzerland, and the English and Dutch overseas colonies. A significant community in France remained in the Cevennes region.
Is there an answer to this question: Whose death caused an increase in the French civil wars?

Answer: Henry II

QUES: The works of Virgil almost from the moment of their publication revolutionized Latin poetry. The Eclogues, Georgics, and above all the Aeneid became standard texts in school curricula with which all educated Romans were familiar. Poets following Virgil often refer intertextually to his works to generate meaning in their own poetry. The Augustan poet Ovid parodies the opening lines of the Aeneid in Amores 1.1.12, and his summary of the Aeneas story in Book 14 of the Metamorphoses, the so-called "mini-Aeneid", has been viewed as a particularly important example of post-Virgilian response to the epic genre. Lucan's epic, the Bellum Civile has been considered an anti-Virgilian epic, disposing with the divine mechanism, treating historical events, and diverging drastically from Virgilian epic practice. The Flavian poet Statius in his 12-book epic Thebaid engages closely with the poetry of Virgil; in his epilogue he advises his poem not to "rival the divine Aeneid, but follow afar and ever venerate its footsteps." In Silius Italicus, Virgil finds one of his most ardent admirers. With almost every line of his epic Punica Silius references Virgil. Indeed, Silius is known to have bought Virgil's tomb and worshipped the poet. Partially as a result of his so-called "Messianic" Fourth Ecloguewidely interpreted later to have predicted the birth of Jesus ChristVirgil was in later antiquity imputed to have the magical abilities of a seer; the Sortes Vergilianae, the process of using Virgil's poetry as a tool of divination, is found in the time of Hadrian, and continued into the Middle Ages. In a similar vein Macrobius in the Saturnalia credits the work of Virgil as the embodiment of human knowledge and experience, mirroring the Greek conception of Homer. Virgil also found commentators in antiquity. Servius, a commentator of the 4th century AD, based his work on the commentary of Donatus. Servius' commentary provides us with a great deal of information about Virgil's life, sources, and references; however, many modern scholars find the variable quality of his work and the often simplistic interpretations frustrating.

Which of Virgil's works was later widely interpreted to have predicted the birth of Jesus Christ?
What is the answer?
ANS:
Fourth Eclogue
