The city lies on approximately 200 deep canyons and hills separating its mesas, creating small pockets of natural open space scattered throughout the city and giving it a hilly geography. Traditionally, San Diegans have built their homes and businesses on the mesas, while leaving the urban canyons relatively wild. Thus, the canyons give parts of the city a segmented feel, creating gaps between otherwise proximate neighborhoods and contributing to a low-density, car-centered environment. The San Diego River runs through the middle of San Diego from east to west, creating a river valley which serves to divide the city into northern and southern segments. The river used to flow into San Diego Bay and its fresh water was the focus of the earliest Spanish explorers.[citation needed] Several reservoirs and Mission Trails Regional Park also lie between and separate developed areas of the city.
What is created by the many canyons and hills throughout San Diego?
****
The answer: small pockets of natural open space

The problem: Answer a question about this article:
There are approximately ten times as many bacterial cells in the human flora as there are human cells in the body, with the largest number of the human flora being in the gut flora, and a large number on the skin. The vast majority of the bacteria in the body are rendered harmless by the protective effects of the immune system, and some are beneficial. However, several species of bacteria are pathogenic and cause infectious diseases, including cholera, syphilis, anthrax, leprosy, and bubonic plague. The most common fatal bacterial diseases are respiratory infections, with tuberculosis alone killing about 2 million people per year, mostly in sub-Saharan Africa. In developed countries, antibiotics are used to treat bacterial infections and are also used in farming, making antibiotic resistance a growing problem. In industry, bacteria are important in sewage treatment and the breakdown of oil spills, the production of cheese and yogurt through fermentation, and the recovery of gold, palladium, copper and other metals in the mining sector, as well as in biotechnology, and the manufacture of antibiotics and other chemicals.
What makes bacteria resistant to antibiotic treatment?
****
The answer: farming

By the early 20th century, mass civil disorder had begun in China, and it was growing continuously. To overcome such problems, Empress Dowager Cixi issued an imperial edict in 1901 calling for reform proposals from the governors-general and governors and initiated the era of the dynasty's "New Policies", also known as the "Late Qing Reform".

In 1374 King Louis of Hungary approved the Privilege of Koszyce (Polish: "przywilej koszycki" or "ugoda koszycka") in Kosice in order to guarantee the Polish throne for his daughter Jadwiga. He broadened the definition of who was a member of the nobility and exempted the entire class from all but one tax (anowy, which was limited to 2 grosze from an (an old measure of land size)). In addition, the King's right to raise taxes was abolished; no new taxes could be raised without the agreement of the nobility. Henceforth, also, district offices (Polish: "urzedy ziemskie") were reserved exclusively for local nobility, as the Privilege of Koszyce forbade the king to grant official posts and major Polish castles to foreign knights. Finally, this privilege obliged the King to pay indemnities to nobles injured or taken captive during a war outside Polish borders.
WHat happened to the kings right to raise taxes?
****
The answer:
abolished
