Problem: Please answer a question about the following article about Wood:
There is a strong relationship between the properties of wood and the properties of the particular tree that yielded it. The density of wood varies with species. The density of a wood correlates with its strength (mechanical properties). For example, mahogany is a medium-dense hardwood that is excellent for fine furniture crafting, whereas balsa is light, making it useful for model building. One of the densest woods is black ironwood.
What property of wood has a correlation to its density?
A: strength
Problem: Please answer a question about the following article about The Legend of Zelda: Twilight Princess:
The team worked on a Wii control scheme, adapting camera control and the fighting mechanics to the new interface. A prototype was created that used a swinging gesture to control the sword from a first-person viewpoint, but was unable to show the variety of Link's movements. When the third-person view was restored, Aonuma thought it felt strange to swing the Wii Remote with the right hand to control the sword in Link's left hand, so the entire Wii version map was mirrored.[p] Details about Wii controls began to surface in December 2005 when British publication NGC Magazine claimed that when a GameCube copy of Twilight Princess was played on the Revolution, it would give the player the option of using the Revolution controller. Miyamoto confirmed the Revolution controller-functionality in an interview with Nintendo of Europe and Time reported this soon after. However, support for the Wii controller did not make it into the GameCube release. At E3 2006, Nintendo announced that both versions would be available at the Wii launch, and had a playable version of Twilight Princess for the Wii.[p] Later, the GameCube release was pushed back to a month after the launch of the Wii.
In what year did Nintendo reveal that the two different releases of Twilight Princess were planned for launch at the same time as the Wii?
A: 2006
Problem: Please answer a question about the following article about Communication:
Effective verbal or spoken communication is dependent on a number of factors and cannot be fully isolated from other important interpersonal skills such as non-verbal communication, listening skills and clarification. Human language can be defined as a system of symbols (sometimes known as lexemes) and the grammars (rules) by which the symbols are manipulated. The word "language" also refers to common properties of languages. Language learning normally occurs most intensively during human childhood. Most of the thousands of human languages use patterns of sound or gesture for symbols which enable communication with others around them. Languages tend to share certain properties, although there are exceptions. There is no defined line between a language and a dialect. Constructed languages such as Esperanto, programming languages, and various mathematical formalism is not necessarily restricted to the properties shared by human languages. Communication is two-way process not merely one-way.
What is an example of a language that is not restricted to properties of human language?
A: programming languages
Problem: Please answer a question about the following article about San Diego:
The development of skyscrapers over 300 feet (91 m) in San Diego is attributed to the construction of the El Cortez Hotel in 1927, the tallest building in the city from 1927 to 1963. As time went on multiple buildings claimed the title of San Diego's tallest skyscraper, including the Union Bank of California Building and Symphony Towers. Currently the tallest building in San Diego is One America Plaza, standing 500 feet (150 m) tall, which was completed in 1991. The downtown skyline contains no super-talls, as a regulation put in place by the Federal Aviation Administration in the 1970s set a 500 feet (152 m) limit on the height of buildings due to the proximity of San Diego International Airport. An iconic description of the skyline includes its skyscrapers being compared to the tools of a toolbox.
What organization regulates building heights in San Diego?
A:
Federal Aviation Administration
