Input: Article: The Greater Richmond area was named the third-best city for business by MarketWatch in September 2007, ranking behind only the Minneapolis and Denver areas and just above Boston. The area is home to six Fortune 500 companies: electric utility Dominion Resources; CarMax; Owens & Minor; Genworth Financial; MeadWestvaco; McKesson Medical-Surgical and Altria Group.

Article: Southeastern Pennsylvania was assigned the 215 area code in 1947 when the North American Numbering Plan of the "Bell System" went into effect. The geographic area covered by the code was split nearly in half in 1994 when area code 610 was created, with the city and its northern suburbs retaining 215. Overlay area code 267 was added to the 215 service area in 1997, and 484 was added to the 610 area in 1999. A plan in 2001 to introduce a third overlay code to both service areas (area code 445 to 215, area code 835 to 610) was delayed and later rescinded.

Question: What area code is used in Philadelphia in 1947?

Here is a question about this article: Some multiracial individuals feel marginalized by U.S. society. For example, when applying to schools or for a job, or when taking standardized tests, Americans are sometimes asked to check boxes corresponding to race or ethnicity.

While some surveys offer an "other" box, this choice groups together individuals of many different multiracial types (ex: European Americans/African-Americans are grouped with Asian/Native American Indians).
What is the answer to this question: What does the "other" box do?
****
So... groups together individuals of many different multiracial types

Question: Read this and answer the question

Mithridates the Great was the ruler of Pontus, a large kingdom in Asia Minor (modern Turkey), from 120 to 63 BC. Mithridates antagonised Rome by seeking to expand his kingdom, and Rome for her part seemed equally eager for war and the spoils and prestige that it might bring. In 88 BC, Mithridates ordered the killing of a majority of the 80,000 Romans living in his kingdom. The massacre was the official reason given for the commencement of hostilities in the First Mithridatic War. The Roman general Lucius Cornelius Sulla forced Mithridates out of Greece proper, but then had to return to Italy to answer the internal threat posed by his rival, Gaius Marius. A peace was made between Rome and Pontus, but this proved only a temporary lull.

How did the ruler of Pontus anger Rome?
Answer:
by seeking to expand his kingdom
