Problem: Geography of the United States:

The Great Plains come to an abrupt end at the Rocky Mountains. The Rocky Mountains form a large portion of the Western U.S., entering from Canada and stretching nearly to Mexico. The Rocky Mountain region is the highest region of the United States by average elevation. The Rocky Mountains generally contain fairly mild slopes and wider peaks compared to some of the other great mountain ranges, with a few exceptions (such as the Teton Mountains in Wyoming and the Sawatch Range in Colorado). The highest peaks of the Rockies are found in Colorado, the tallest peak being Mount Elbert at 14,440 ft (4,400 m). The Rocky Mountains contain some of the most spectacular, and well known scenery in the world. In addition, instead of being one generally continuous and solid mountain range, it is broken up into a number of smaller, intermittent mountain ranges, forming a large series of basins and valleys.

Which northern country do the Rocky Mountains terminate at?

A: Mexico

Problem: Florida High Speed Rail was a proposed government backed high-speed rail system that would have connected Miami, Orlando, and Tampa. The first phase was planned to connect Orlando and Tampa and was offered federal funding, but it was turned down by Governor Rick Scott in 2011. The second phase of the line was envisioned to connect Miami. By 2014, a private project known as All Aboard Florida by a company of the historic Florida East Coast Railway began construction of a higher-speed rail line in South Florida that is planned to eventually terminate at Orlando International Airport.
What company is responsible for All Aboard Florida?

Answer: Florida East Coast Railway

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Interest in Darwin's writings continues, and scholars have generated an extensive literature, the Darwin Industry, about his life and work. The text of Origin itself has been subject to much analysis including a variorum, detailing the changes made in every edition, first published in 1959, and a concordance, an exhaustive external index published in 1981. Worldwide commemorations of the 150th anniversary of the publication of On the Origin of Species and the bicentenary of Darwin's birth were scheduled for 2009. They celebrated the ideas which "over the last 150 years have revolutionised our understanding of nature and our place within it".
What were the celebrants honoring with their commemorations?
A: They celebrated the ideas which "over the last 150 years have revolutionised our understanding of nature and our place within it".

Context and question: An argument for idealism, such as those of Hegel and Berkeley, is ipso facto an argument against materialism. Matter can be argued to be redundant, as in bundle theory, and mind-independent properties can in turn be reduced to subjective percepts. Berkeley presents an example of the latter by pointing out that it is impossible to gather direct evidence of matter, as there is no direct experience of matter; all that is experienced is perception, whether internal or external. As such, the existence of matter can only be assumed from the apparent (perceived) stability of perceptions; it finds absolutely no evidence in direct experience.
Why is it possible to gather direct evidence?
Answer: unanswerable

Question: In 1903, Josiah White III bought a parcel of land near Ohio Avenue and the boardwalk and built the Queen Anne style Marlborough House. The hotel was a hit and, in 190506, he chose to expand the hotel and bought another parcel of land next door to his Marlborough House. In an effort to make his new hotel a source of conversation, White hired the architectural firm of Price and McLanahan. The firm made use of reinforced concrete, a new building material invented by Jean-Louis Lambot in 1848 (Joseph Monier received the patent in 1867). The hotel's Spanish and Moorish themes, capped off with its signature dome and chimneys, represented a step forward from other hotels that had a classically designed influence. White named the new hotel the Blenheim and merged the two hotels into the Marlborough-Blenheim. Bally's Atlantic City was later constructed at this location.
Is there an answer to this question: What was the name of the hotel built by Josiah White III?

Answer: Marlborough House
