Problem: New Haven, Connecticut:

The New Haven Division buses follow routes that had originally been covered by trolley service. Horse-drawn steetcars began operating in New Haven in the 1860s, and by the mid-1890s all the lines had become electric. In the 1920s and 1930s, some of the trolley lines began to be replaced by bus lines, with the last trolley route converted to bus in 1948. The City of New Haven is in the very early stages of considering the restoration of streetcar (light-rail) service, which has been absent since the postwar period.

In what year was the final trolley route in New Haven converted to a bus line?

A: 1948

Problem: In philosophy, emotions are studied in sub-fields such as ethics, the philosophy of art (for example, sensoryemotional values, and matters of taste and sentimentality), and the philosophy of music (see also Music and emotion). In history, scholars examine documents and other sources to interpret and analyze past activities; speculation on the emotional state of the authors of historical documents is one of the tools of interpretation. In literature and film-making, the expression of emotion is the cornerstone of genres such as drama, melodrama, and romance. In communication studies, scholars study the role that emotion plays in the dissemination of ideas and messages. Emotion is also studied in non-human animals in ethology, a branch of zoology which focuses on the scientific study of animal behavior. Ethology is a combination of laboratory and field science, with strong ties to ecology and evolution. Ethologists often study one type of behavior (for example, aggression) in a number of unrelated animals.
Along with laboratory work, what doesn't an ethologist engage in?

Q: What is a question about this article? If the question is unanswerable, say "unanswerable".
Developers also found the machine difficult to program for. In 2007, Gabe Newell of Valve said "The PS3 is a total disaster on so many levels, I think it's really clear that Sony lost track of what customers and what developers wanted". He continued "I'd say, even at this late date, they should just cancel it and do a do over. Just say, 'This was a horrible disaster and we're sorry and we're going to stop selling this and stop trying to convince people to develop for it'". Doug Lombardi VP of Marketing for Valve has since stated that they are interested in developing for the console and are looking to hire talented PS3 programmers for future projects. He later restated Valve's position, "Until we have the ability to get a PS3 team together, until we find the people who want to come to Valve or who are at Valve who want to work on that, I don't really see us moving to that platform". At Sony's E3 2010 press conference, Newell made a live appearance to recant his previous statements, citing Sony's move to make the system more developer friendly, and to announce that Valve would be developing Portal 2 for the system. He also claimed that the inclusion of Steamworks (Valve's system to automatically update their software independently) would help to make the PS3 version of Portal 2 the best console version on the market.
In what year did Gabe Newell call the PS3 "a total disaster"?
A: 2007

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.
Is there an answer to this question: What city was chosen as the capital in 1792?

Answer: unanswerable

QUES: Isaac Newton (16431727) inherited Descartes' mechanical conception of matter. In the third of his "Rules of Reasoning in Philosophy", Newton lists the universal qualities of matter as "extension, hardness, impenetrability, mobility, and inertia". Similarly in Optics he conjectures that God created matter as "solid, massy, hard, impenetrable, movable particles", which were "...even so very hard as never to wear or break in pieces". The "primary" properties of matter were amenable to mathematical description, unlike "secondary" qualities such as color or taste. Like Descartes, Newton rejected the essential nature of secondary qualities.

Both primary and secondary properties are suited to what form of description?
