The problem: Answer a question about this article:
The general effect of the water content upon the wood substance is to render it softer and more pliable. A similar effect of common observation is in the softening action of water on rawhide, paper, or cloth. Within certain limits, the greater the water content, the greater its softening effect.
What material we use to write or print on, like wood, becomes softer and more pliable when wet?
****
The answer: paper


Problem: Please answer a question about the following article about Dwight D. Eisenhower:
In late 1954, Gen. J. Lawton Collins was made ambassador to "Free Vietnam" (the term South Vietnam came into use in 1955), effectively elevating the country to sovereign status. Collins' instructions were to support the leader Ngo Dinh Diem in subverting communism, by helping him to build an army and wage a military campaign. In February 1955, Eisenhower dispatched the first American soldiers to Vietnam as military advisors to Diem's army. After Diem announced the formation of the Republic of Vietnam (RVN, commonly known as South Vietnam) in October, Eisenhower immediately recognized the new state and offered military, economic, and technical assistance.
Along with Free Vietnam, what was another term for South Vietnam?
A: Republic of Vietnam


Question: Read this and answer the question

Raleigh is an early example in the United States of a planned city, chosen as the site of the state capital in 1788 and incorporated in 1792 as such. The city was originally laid out in a grid pattern with the North Carolina State Capitol in Union Square at the center. In the United States Civil War the city was spared from any significant battle, only falling in the closing days of the war, though it did not escape the economic hardships that plagued the rest of the American South during the Reconstruction Era. The twentieth century saw the opening of the Research Triangle Park in 1959, and with the jobs it created the region and city saw a large influx of population, making it one of the fastest growing communities in the United States by the early 21st century.

What war was near the city?
Answer: Civil War


Problem: Due to reciprocity (discussed above) the gain of an antenna used for transmitting must be proportional to its effective area when used for receiving. Consider an antenna with no loss, that is, one whose electrical efficiency is 100%. It can be shown that its effective area averaged over all directions must be equal to λ2/4π, the wavelength squared divided by 4π. Gain is defined such that the average gain over all directions for an antenna with 100% electrical efficiency is equal to 1. Therefore, the effective area Aeff in terms of the gain G in a given direction is given by:
What must the relationship of an antenna and the receiving area be due to reciprocity?
The answer is the following: proportional


Auto racing is also popular in the area. The Richmond International Raceway (RIR) has hosted NASCAR Sprint Cup races since 1953, as well as the Capital City 400 from 1962 − 1980. RIR also hosted IndyCar's Suntrust Indy Challenge from 2001 − 2009. Another track, Southside Speedway, has operated since 1959 and sits just southwest of Richmond in Chesterfield County. This .333-mile (0.536 km) oval short-track has become known as the "Toughest Track in the South" and "The Action Track", and features weekly stock car racing on Friday nights. Southside Speedway has acted as the breeding grounds for many past NASCAR legends including Richard Petty, Bobby Allison and Darrell Waltrip, and claims to be the home track of NASCAR superstar Denny Hamlin.
When did the Suntrust Indy Challenge stop being run at RIR?
2009


Here is a question about this article: On average, the mountains of the western states receive the highest levels of snowfall on Earth. The greatest annual snowfall level is at Mount Rainier in Washington, at 692 inches (1,758 cm); the record there was 1,122 inches (2,850 cm) in the winter of 1971–72. This record was broken by the Mt. Baker Ski Area in northwestern Washington which reported 1,140 inches (2,896 cm) of snowfall for the 1998-99 snowfall season. Other places with significant snowfall outside the Cascade Range are the Wasatch Mountains, near the Great Salt Lake, the San Juan Mountains in Colorado, and the Sierra Nevada, near Lake Tahoe.
What is the answer to this question: The Sierra Nevadas are located near which lake?
****
So...
Lake Tahoe
