Problem: IPod:

The third generation began including a 30-pin dock connector, allowing for FireWire or USB connectivity. This provided better compatibility with non-Apple machines, as most of them did not have FireWire ports at the time. Eventually Apple began shipping iPods with USB cables instead of FireWire, although the latter was available separately. As of the first-generation iPod Nano and the fifth-generation iPod Classic, Apple discontinued using FireWire for data transfer (while still allowing for use of FireWire to charge the device) in an attempt to reduce cost and form factor. As of the second-generation iPod Touch and the fourth-generation iPod Nano, FireWire charging ability has been removed. The second-, third-, and fourth-generation iPod Shuffle uses a single 3.5 mm minijack phone connector which acts as both a headphone jack and a data port for the dock.

Starting with which generation of iPod Nano was FireWire charging functionality no longer available?

A: fourth

Problem: Canadian Armed Forces:

This unified institution consists of sea, land, and air elements referred to as the Royal Canadian Navy (RCN), Canadian Army, and Royal Canadian Air Force (RCAF). Personnel may belong to either the Regular Force or the Reserve Force, which has four sub-components: the Primary Reserve, Supplementary Reserve, Cadet Organizations Administration and Training Service, and the Canadian Rangers. Under the National Defence Act, the Canadian Armed Forces are an entity separate and distinct from the Department of National Defence (the federal government department responsible for administration and formation of defence policy), which also exists as the civilian support system for the Forces.

What act does not define the CAF?

A: unanswerable

Problem: Napoleon:

Unhappy with this change of policy by the Portuguese government, Napoleon sent an army to invade Portugal. On 17 October 1807, 24,000 French troops under General Junot crossed the Pyrenees with Spanish cooperation and headed towards Portugal to enforce Napoleon's orders. This attack was the first step in what would eventually become the Peninsular War, a six-year struggle that significantly sapped French strength. Throughout the winter of 1808, French agents became increasingly involved in Spanish internal affairs, attempting to incite discord between members of the Spanish royal family. On 16 February 1808, secret French machinations finally materialized when Napoleon announced that he would intervene to mediate between the rival political factions in the country. Marshal Murat led 120,000 troops into Spain and the French arrived in Madrid on 24 March, where wild riots against the occupation erupted just a few weeks later. Napoleon appointed his brother, Joseph Bonaparte, as the new King of Spain in the summer of 1808. The appointment enraged a heavily religious and conservative Spanish population. Resistance to French aggression soon spread throughout the country. The shocking French defeat at the Battle of Bailen in July gave hope to Napoleon's enemies and partly persuaded the French emperor to intervene in person.

When did Napoleon's invasion of Portugal begin?

A: 17 October 1807

Problem: Nutrition:

In 1816, Francois Magendie discovered that dogs fed only carbohydrates (sugar), fat (olive oil), and water died evidently of starvation, but dogs also fed protein survived, identifying protein as an essential dietary component. William Prout in 1827 was the first person to divide foods into carbohydrates, fat, and protein. During the 19th century, Jean-Baptiste Dumas and Justus von Liebig quarrelled over their shared belief that animals get their protein directly from plants (animal and plant protein are the same and that humans do not create organic compounds). With a reputation as the leading organic chemist of his day but with no credentials in animal physiology, Liebig grew rich making food extracts like beef bouillon and infant formula that were later found to be of questionable nutritious value. In the 1860s, Claude Bernard discovered that body fat can be synthesized from carbohydrate and protein, showing that the energy in blood glucose can be stored as fat or as glycogen.

Who first began dividing foods into categories?

A:
William Prout
