Problem: Old English:

Modern editions of Old English manuscripts generally introduce some additional conventions. The modern forms of Latin letters are used, including g in place of the insular G, s for long S, and others which may differ considerably from the insular script, notably e, f and r. Macrons are used to indicate long vowels, where usually no distinction was made between long and short vowels in the originals. (In some older editions an acute accent mark was used for consistency with Old Norse conventions.) Additionally, modern editions often distinguish between velar and palatal c and g by placing dots above the palatals: c, g. The letter wynn is usually replaced with w, but sc, eth and thorn are normally retained (except when eth is replaced by thorn).

What form of c, when written, contains a dot over the letter?
---
A: palatal

Problem: In the early part of the 20th century, San Diego hosted two World's Fairs: the Panama-California Exposition in 1915 and the California Pacific International Exposition in 1935. Both expositions were held in Balboa Park, and many of the Spanish/Baroque-style buildings that were built for those expositions remain to this day as central features of the park. The buildings were intended to be temporary structures, but most remained in continuous use until they progressively fell into disrepair. Most were eventually rebuilt, using castings of the original facades to retain the architectural style. The menagerie of exotic animals featured at the 1915 exposition provided the basis for the San Diego Zoo. During the 1950s there was a citywide festival called Fiesta del Pacifico highlighting the area's Spanish and Mexican past. In the 2010s there was a proposal for a large-scale celebration of the 100th anniversary of Balboa Park, but the plans were abandoned when the organization tasked with putting on the celebration went out of business.
What festival was celebrated in the 1950s in recognition of the city's Mexican and Spanish past?
---
Answer: Fiesta del Pacifico

Context and question: Cubism formed an important link between early-20th-century art and architecture. The historical, theoretical, and socio-political relationships between avant-garde practices in painting, sculpture and architecture had early ramifications in France, Germany, the Netherlands and Czechoslovakia. Though there are many points of intersection between Cubism and architecture, only a few direct links between them can be drawn. Most often the connections are made by reference to shared formal characteristics: faceting of form, spatial ambiguity, transparency, and multiplicity.
In which four countries were the impacts of avant garde art particularly weak?
Answer: unanswerable

The decline in the value of the U.S. dollar corresponds to price inflation, which is a rise in the general level of prices of goods and services in an economy over a period of time. A consumer price index (CPI) is a measure estimating the average price of consumer goods and services purchased by households. The United States Consumer Price Index, published by the Bureau of Labor Statistics, is a measure estimating the average price of consumer goods and services in the United States. It reflects inflation as experienced by consumers in their day-to-day living expenses. A graph showing the U.S. CPI relative to 19821984 and the annual year-over-year change in CPI is shown at right.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What does the Bureau of Labor Statistics estimate?
Ah, so..
