Problem: Melbourne:

In recent years, Melton, Wyndham and Casey, part of the Melbourne statistical division, have recorded the highest growth rate of all local government areas in Australia. Melbourne could overtake Sydney in population by 2028, The ABS has projected in two scenarios that Sydney will remain larger than Melbourne beyond 2056, albeit by a margin of less than 3% compared to a margin of 12% today. Melbourne's population could overtake that of Sydney by 2037 or 2039, according to the first scenario projected by the ABS; primarily due to larger levels of internal migration losses assumed for Sydney. Another study claims that Melbourne will surpass Sydney in population by 2040.

According to the first scenario projected by the ABS, how soon could Melbourne overtake Sydney's population level?

A: 2037 or 2039


Problem: The first PCBs used through-hole technology, mounting electronic components by leads inserted through holes on one side of the board and soldered onto copper traces on the other side. Boards may be single-sided, with an unplated component side, or more compact double-sided boards, with components soldered on both sides. Horizontal installation of through-hole parts with two axial leads (such as resistors, capacitors, and diodes) is done by bending the leads 90 degrees in the same direction, inserting the part in the board (often bending leads located on the back of the board in opposite directions to improve the part's mechanical strength), soldering the leads, and trimming off the ends. Leads may be soldered either manually or by a wave soldering machine.
In through-hole construction, what are the leads on the front attached to on the back?

Answer: copper traces

Within the city there have been two tram networks in operation. A proposal to develop a horse-drawn tram (linking the city's railway termini) was made by American George Francis Train in the 1860s, and implemented in 1872 by the Cork Tramway Company. However, the company ceased trading in 1875 after Cork Corporation refused permission to extend the line, mainly because of objections from cab operators to the type of tracks which – although they were laid to the Irish national railway gauge of 5 ft 3in – protruded from the road surface.[citation needed]
How many tram systems were in Cork?
A: two


Context and question: The working memory model explains many practical observations, such as why it is easier to do two different tasks (one verbal and one visual) than two similar tasks (e.g., two visual), and the aforementioned word-length effect. However, the concept of a central executive as noted here has been criticised as inadequate and vague.[citation needed] Working memory is also the premise for what allows us to do everyday activities involving thought. It is the section of memory where we carry out thought processes and use them to learn and reason about topics.
What does the non-working memory model explain?
Answer: unanswerable


Question: The Lacey Act of 1900 was the first federal law that regulated commercial animal markets. It prohibited interstate commerce of animals killed in violation of state game laws, and covered all fish and wildlife and their parts or products, as well as plants. Other legislation followed, including the Migratory Bird Conservation Act of 1929, a 1937 treaty prohibiting the hunting of right and gray whales, and the Bald Eagle Protection Act of 1940. These later laws had a low cost to society–the species were relatively rare–and little opposition was raised.
Is there an answer to this question: What legislation was considered costly?

Answer: unanswerable


QUES: Yale is noted for its largely Collegiate Gothic campus as well as for several iconic modern buildings commonly discussed in architectural history survey courses: Louis Kahn's Yale Art Gallery and Center for British Art, Eero Saarinen's Ingalls Rink and Ezra Stiles and Morse Colleges, and Paul Rudolph's Art & Architecture Building. Yale also owns and has restored many noteworthy 19th-century mansions along Hillhouse Avenue, which was considered the most beautiful street in America by Charles Dickens when he visited the United States in the 1840s. In 2011, Travel+Leisure listed the Yale campus as one of the most beautiful in the United States.

When did Travel + Leisure list Yale as one of the most beautiful campuses?
