Question: Read this and answer the question

Several dozen radioisotopes have been characterized. 65Zn, which has a half-life of 243.66 days, is the most long-lived radioisotope, followed by 72Zn with a half-life of 46.5 hours. Zinc has 10 nuclear isomers. 69mZn has the longest half-life, 13.76 h. The superscript m indicates a metastable isotope. The nucleus of a metastable isotope is in an excited state and will return to the ground state by emitting a photon in the form of a gamma ray. 61Zn has three excited states and 73Zn has two. The isotopes 65Zn, 71Zn, 77Zn and 78Zn each have only one excited state.

What does a metastable isotope do to return to ground state from an excited state?
Answer: emitting a photon in the form of a gamma ray


Problem: The New Haven area supports several medical facilities that are considered some of the best hospitals in the country. There are two major medical centers downtown: Yale – New Haven Hospital has four pavilions, including the Yale – New Haven Children's Hospital and the Smilow Cancer Hospital; the Hospital of Saint Raphael is several blocks north, and touts its excellent cardiac emergency care program. Smaller downtown health facilities are the Temple Medical Center located downtown on Temple Street, Connecticut Mental Health Center/ across Park Street from Y-NHH, and the Hill Health Center, which serves the working-class Hill neighborhood. A large Veterans Affairs hospital is located in neighboring West Haven. To the west in Milford is Milford Hospital, and to the north in Meriden is the MidState Medical Center.
What overarching New Haven medical center is the Smilow Cancer Hospital a part of?
The answer is the following: Yale – New Haven Hospital


Australian rules football and cricket are the most popular sports in Melbourne. It is considered the spiritual home of the two sports in Australia. The first official Test cricket match was played at the Melbourne Cricket Ground in March 1877. The origins of Australian rules football can be traced to matches played next to the MCG in 1858. The Australian Football League is headquartered at Docklands Stadium. Nine of the League's teams are based in the Melbourne metropolitan area: Carlton, Collingwood, Essendon, Hawthorn, Melbourne, North Melbourne, Richmond, St Kilda, and Western Bulldogs. Up to five AFL matches are played each week in Melbourne, attracting an average 40,000 people per game. Additionally, the city annually hosts the AFL Grand Final.
Up to how many AFL matches are played each week in Melbourne?
five


Input: Software testing
Software faults occur through the following processes. A programmer makes an error (mistake), which results in a defect (fault, bug) in the software source code. If this defect is executed, in certain situations the system will produce wrong results, causing a failure. Not all defects will necessarily result in failures. For example, defects in dead code will never result in failures. A defect can turn into a failure when the environment is changed. Examples of these changes in environment include the software being run on a new computer hardware platform, alterations in source data, or interacting with different software. A single defect may result in a wide range of failure symptoms.

What is the result of the programmer making a mistake?
Output: defect (fault, bug)


Input: Article: CBC Television stations can be received in many United States communities along the Canadian border over-the-air and have a significant audience in those areas. Such a phenomenon can also take place within Great Lakes communities such as Ashtabula, Ohio, which received programming from the CBC's London, Ontario, transmitter, based upon prevailing atmospheric conditions over Lake Erie. As of September 2010 CBC shut down its analogue transmitter and decided not to replace it with a digital transmitter. As a result, there is now a giant hole in the coverage of CBC in South-Western Ontario. Both CBC - Toronto and CBC - Windsor are both over 100 miles from London, ON and out of range for even the largest antennas[citation needed].

Now answer this question: When did CBC shut down its analogue transmitter?

Output: September 2010


Problem: While inert gas reduces filament evaporation, it also conducts heat from the filament, thereby cooling the filament and reducing efficiency. At constant pressure and temperature, the thermal conductivity of a gas depends upon the molecular weight of the gas and the cross sectional area of the gas molecules. Higher molecular weight gasses have lower thermal conductivity, because both the molecular weight is higher and also the cross sectional area is higher. Xenon gas improves efficiency because of its high molecular weight, but is also more expensive, so its use is limited to smaller lamps.
What affects the thermal conductivity of a gas?
The answer is the following:
molecular weight of the gas and the cross sectional area of the gas molecules
