Article: In diffuse-porous woods, as has been stated, the vessels or pores are even-sized, so that the water conducting capability is scattered throughout the ring instead of collected in the earlywood. The effect of rate of growth is, therefore, not the same as in the ring-porous woods, approaching more nearly the conditions in the conifers. In general it may be stated that such woods of medium growth afford stronger material than when very rapidly or very slowly grown. In many uses of wood, total strength is not the main consideration. If ease of working is prized, wood should be chosen with regard to its uniformity of texture and straightness of grain, which will in most cases occur when there is little contrast between the latewood of one season's growth and the earlywood of the next.

Question: What kind of wood has all similarly sized vessels?
Ans: diffuse-porous

Here is a question about this article: The Chronicle provides a mythic tale of Oleg's death. A sorcerer prophesies that the death of the Grand Prince would be associated with a certain horse. Oleg has the horse sequestered, and it later dies. Oleg goes to visit the horse and stands over the carcass, gloating that he had outlived the threat, when a snake strikes him from among the bones, and he soon becomes ill and dies. The Chronicle reports that Prince Igor succeeded Oleg in 913, and after some brief conflicts with the Drevlians and the Pechenegs, a period of peace ensued for over twenty years.
What is the answer to this question: WHo succeeded Oleg in 913?
****
So... Prince Igor

Freemasonry consists of fraternal organisations that trace their origins to the local fraternities of stonemasons, which from the end of the fourteenth century regulated the qualifications of stonemasons and their interaction with authorities and clients. The degrees of freemasonry retain the three grades of medieval craft guilds, those of Apprentice, Journeyman or fellow (now called Fellowcraft), and Master Mason. These are the degrees offered by Craft (or Blue Lodge) Freemasonry. Members of these organisations are known as Freemasons or Masons. There are additional degrees, which vary with locality and jurisdiction, and are usually administered by different bodies than the craft degrees.
Where are the origins of Freemasonry?
****
The answer: local fraternities of stonemasons

Problem: Please answer a question about the following article about Richmond, Virginia:
As the primary former Capital of the Confederate States of America, Richmond is home to many museums and battlefields of the American Civil War. Near the riverfront is the Richmond National Battlefield Park Visitors Center and the American Civil War Center at Historic Tredegar, both housed in the former buildings of the Tredegar Iron Works, where much of the ordnance for the war was produced. In Court End, near the Virginia State Capitol, is the Museum of the Confederacy, along with the Davis Mansion, also known as the White House of the Confederacy; both feature a wide variety of objects and material from the era. The temporary home of former Confederate General Robert E. Lee still stands on Franklin Street in downtown Richmond. The history of slavery and emancipation are also increasingly represented: there is a former slave trail along the river that leads to Ancarrow's Boat Ramp and Historic Site which has been developed with interpretive signage, and in 2007, the Reconciliation Statue was placed in Shockoe Bottom, with parallel statues placed in Liverpool and Benin representing points of the Triangle Trade.
Where are the Reconciliation Statues outside Richmond located?
A: Liverpool and Benin

Several systems were proposed as the new standard for the US, including the Japanese MUSE system, but all were rejected by the FCC because of their higher bandwidth requirements. At this time, the number of television channels was growing rapidly and bandwidth was already a problem. A new standard had to be more efficient, needing less bandwidth for HDTV than the existing NTSC.

Why did the FCC reject systems such as MUSE?
Answer: their higher bandwidth requirements

The five Great Lakes are located in the north-central portion of the country, four of them forming part of the border with Canada, only Lake Michigan situated entirely within United States. The southeast United States contain subtropical forests and, near the gulf coast, mangrove wetlands, especially in Florida. West of the Appalachians lies the Mississippi River basin and two large eastern tributaries, the Ohio River and the Tennessee River. The Ohio and Tennessee Valleys and the Midwest consist largely of rolling hills and productive farmland, stretching south to the Gulf Coast.
What type of land makes up the Ohio and Tennessee valleys?
rolling hills and productive farmland
