The Queen surpassed her great-great-grandmother, Queen Victoria, to become the longest-lived British monarch in December 2007, and the longest-reigning British monarch on 9 September 2015. She was celebrated in Canada as the "longest-reigning sovereign in Canada's modern era". (King Louis XIV of France reigned over part of Canada for longer.) She is the longest-reigning queen regnant in history, the world's oldest reigning monarch and second-longest-serving current head of state after King Bhumibol Adulyadej of Thailand.
Who did Elizabeth surpass in longest lived British monarch?
****
The answer: Queen Victoria

Problem: Please answer a question about the following article about Capacitor:
Ripple current is the AC component of an applied source (often a switched-mode power supply) whose frequency may be constant or varying. Ripple current causes heat to be generated within the capacitor due to the dielectric losses caused by the changing field strength together with the current flow across the slightly resistive supply lines or the electrolyte in the capacitor. The equivalent series resistance (ESR) is the amount of internal series resistance one would add to a perfect capacitor to model this. Some types of capacitors, primarily tantalum and aluminum electrolytic capacitors, as well as some film capacitors have a specified rating value for maximum ripple current.
What is the name given to the amount of internal series resistance needed to add to an ideal capacitor model in order to represent the heat generated by dielectric losses?
A: equivalent series resistance (ESR)

The development of a three-field rotation system for planting crops[AA] increased the usage of land from one half in use each year under the old two-field system to two-thirds under the new system, with a consequent increase in production. The development of the heavy plough allowed heavier soils to be farmed more efficiently, aided by the spread of the horse collar, which led to the use of draught horses in place of oxen. Horses are faster than oxen and require less pasture, factors that aided the implementation of the three-field system.

What invention led to an increase in efficiency in the farming of heavy soils?
Answer: the heavy plough

Problem: In 1920 French Equatorial Africa was established and Ubangi-Shari was administered from Brazzaville. During the 1920s and 1930s the French introduced a policy of mandatory cotton cultivation, a network of roads was built, attempts were made to combat sleeping sickness and Protestant missions were established to spread Christianity. New forms of forced labor were also introduced and a large number of Ubangians were sent to work on the Congo-Ocean Railway. Many of these forced laborers died of exhaustion, illness, or the poor conditions which claimed between 20% and 25% of the 127,000 workers.
When was Equatorial Africa established?
The answer is the following: 1920

The Times faced financial extinction in 1890 under Arthur Fraser Walter, but it was rescued by an energetic editor, Charles Frederic Moberly Bell. During his tenure (18901911), The Times became associated with selling the Encyclopdia Britannica using aggressive American marketing methods introduced by Horace Everett Hooper and his advertising executive, Henry Haxton. Due to legal fights between the Britannica's two owners, Hooper and Walter Montgomery Jackson, The Times severed its connection in 1908 and was bought by pioneering newspaper magnate, Alfred Harmsworth, later Lord Northcliffe.
Which editor nearly ruined The Times in 1890?
Arthur Fraser Walter

Here is a question about this article: The Kalahari Desert, an arid region shared with South Africa and Botswana, is one of Namibia's well-known geographical features. The Kalahari, while popularly known as a desert, has a variety of localised environments, including some verdant and technically non-desert areas. One of these, known as the Succulent Karoo, is home to over 5,000 species of plants, nearly half of them endemic; Approximately 10 percent of the world's succulents are found in the Karoo. The reason behind this high productivity and endemism may be the relatively stable nature of precipitation.
What is the answer to this question: What Desert is shared between South Africa and Botswana?
****
So...
Kalahari Desert
