Article: With over 90 million inhabitants, Egypt is the most populous country in North Africa and the Arab World, the third-most populous in Africa (after Nigeria and Ethiopia), and the fifteenth-most populous in the world. The great majority of its people live near the banks of the Nile River, an area of about 40,000 square kilometres (15,000 sq mi), where the only arable land is found. The large regions of the Sahara desert, which constitute most of Egypt's territory, are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.

Question: How many inhabitants does Egypt have?
Ans: over 90 million


Article: Having small population size is a characteristic almost universally inherent to apex predators, humans and dogs by far the most blatant exceptions. Low numbers wouldn't be a problem for apex predators if there was an abundance of prey and no competition or niche overlap, a scenario that is rarely, if ever, encountered in the wild. The competitive exclusion principle states that if two species' ecological niches overlap, there is a very high likelihood of competition as both species are in direct competition for the same resources. This factor alone could lead to the extirpation of one or both species, but is compounded by the added factor of prey abundance.

Question: What other factor is relevant to the competitive exclusion principle?
Ans: prey abundance


Article: The mutineers seized the Citadel, a Supreme Junta government took over, and on 26–28 June, Napoleon's Marshal Moncey attacked the city with a column of 9,000 French imperial troops in the First Battle of Valencia. He failed to take the city in two assaults and retreated to Madrid. Marshal Suchet began a long siege of the city in October 1811, and after intense bombardment forced it to surrender on 8 January 1812. After the capitulation, the French instituted reforms in Valencia, which became the capital of Spain when the Bonapartist pretender to the throne, José I (Joseph Bonaparte, Napoleon's elder brother), moved the Court there in the summer of 1812. The disaster of the Battle of Vitoria on 21 June 1813 obliged Suchet to quit Valencia, and the French troops withdrew in July.

Question: Who attacked Valencia with French soldiers but failed to capture it?
Ans: Moncey


Article: Gram quantities of various copper salts have been taken in suicide attempts and produced acute copper toxicity in humans, possibly due to redox cycling and the generation of reactive oxygen species that damage DNA. Corresponding amounts of copper salts (30 mg/kg) are toxic in animals. A minimum dietary value for healthy growth in rabbits has been reported to be at least 3 ppm in the diet. However, higher concentrations of copper (100 ppm, 200 ppm, or 500 ppm) in the diet of rabbits may favorably influence feed conversion efficiency, growth rates, and carcass dressing percentages.

Question: What is a major benefit to rabbits having a higher concentration of copper in their diet?
Ans:
growth rates
