Problem: Philadelphia:

The number of shootings in the city has declined significantly in the last 10 years. Shooting incidents peaked in 2006 when 1,857 shootings were recorded. That number has dropped 44 percent to 1,047 shootings in 2014. Similarly, major crimes in the city has decreased gradually in the last ten years since its peak in 2006 when 85,498 major crimes were reported. In the past three years, the number of reported major crimes fell 11 percent to a total of 68,815. Violent crimes, which include homicide, rape, aggravated assault, and robbery, decreased 14 percent in the past three years with a reported 15,771 occurrences in 2014. Based on the rate of violent crimes per 1,000 residents in American cities with 25,000 people or more, Philadelphia was ranked as the 54th most dangerous city in 2015.

What rank in danger does Philadelphia have in the U.S.?

A: 54th


Problem: John, King of England:

Henry II wanted to secure the southern borders of Aquitaine and decided to betroth his youngest son to Alais, the daughter and heiress of Humbert III of Savoy. As part of this agreement John was promised the future inheritance of Savoy, Piedmont, Maurienne, and the other possessions of Count Humbert. For his part in the potential marriage alliance, Henry II transferred the castles of Chinon, Loudun and Mirebeau into John's name; as John was only five years old his father would continue to control them for practical purposes. Henry the Young King was unimpressed by this; although he had yet to be granted control of any castles in his new kingdom, these were effectively his future property and had been given away without consultation. Alais made the trip over the Alps and joined Henry II's court, but she died before marrying John, which left the prince once again without an inheritance.

What castles did Henry II transfer into John's name?
---
A: Chinon, Loudun and Mirebeau


Problem: Nintendo Entertainment System:

When Nintendo released the NES in the US, the design styling was deliberately different from that of other game consoles. Nintendo wanted to distinguish its product from those of competitors and to avoid the generally poor reputation that game consoles had acquired following the video game crash of 1983. One result of this philosophy was to disguise the cartridge slot design as a front-loading zero insertion force (ZIF) cartridge socket, designed to resemble the front-loading mechanism of a VCR. The newly designed connector worked quite well when both the connector and the cartridges were clean and the pins on the connector were new. Unfortunately, the ZIF connector was not truly zero insertion force. When a user inserted the cartridge into the NES, the force of pressing the cartridge down and into place bent the contact pins slightly, as well as pressing the cartridge’s ROM board back into the cartridge itself. Frequent insertion and removal of cartridges caused the pins to wear out from repeated usage over the years and the ZIF design proved more prone to interference by dirt and dust than an industry-standard card edge connector. These design issues were not alleviated by Nintendo’s choice of materials; the console slot nickel connector springs would wear due to design and the game cartridge copper connectors were also prone to tarnishing. Many players would try to alleviate issues in the game caused by this corrosion by blowing into the cartridges, then reinserting them, which actually hurt the copper connectors by speeding up the tarnishing.

The ZIF insertion used by Nintendo was set to emulate what device?

A: VCR


Problem: Planck constant:

Prior to Einstein's paper, electromagnetic radiation such as visible light was considered to behave as a wave: hence the use of the terms "frequency" and "wavelength" to characterise different types of radiation. The energy transferred by a wave in a given time is called its intensity. The light from a theatre spotlight is more intense than the light from a domestic lightbulb; that is to say that the spotlight gives out more energy per unit time and per unit space(and hence consumes more electricity) than the ordinary bulb, even though the colour of the light might be very similar. Other waves, such as sound or the waves crashing against a seafront, also have their own intensity. However, the energy account of the photoelectric effect didn't seem to agree with the wave description of light.

What is the name for the amount of energy transfered by a wave in a given time?

A:
intensity
