Historians agree that Napoleon's remarkable personality was one key to his influence. They emphasize the strength of his ambition that took him from an obscure village to command of most of Europe. George F. E. Rudé stresses his "rare combination of will, intellect and physical vigour." At 5 ft 6 in (168 cm), he was not physically imposing but in one-on-one situations he typically had a hypnotic impact on people and seemingly bent the strongest leaders to his will. He understood military technology, but was not an innovator in that regard. He was an innovator in using the financial, bureaucratic, and diplomatic resources of France. He could rapidly dictate a series of complex commands to his subordinates, keeping in mind where major units were expected to be at each future point, and like a chess master, "seeing" the best plays moves ahead.
How tall was Napoleon in centimeters?
****
The answer: 168 cm

Most major airports provide commercial outlets for products and services. Most of these companies, many of which are internationally known brands, are located within the departure areas. These include clothing boutiques and restaurants. Prices charged for items sold at these outlets are generally higher than those outside the airport. However, some airports now regulate costs to keep them comparable to "street prices". This term is misleading as prices often match the manufacturers' suggested retail price (MSRP) but are almost never discounted.[citation needed]
Where are most of these companies located in an airport?
****
The answer: within the departure areas
