Tuvalu experiences the effects of El Nino and La Nina caused by changes in ocean temperatures in the equatorial and central Pacific. El Nino effects increase the chances of tropical storms and cyclones, while La Nina effects increase the chances of drought. Typically the islands of Tuvalu receive between 200 to 400 mm (8 to 16 in) of rainfall per month. However, in 2011 a weak La Nina effect caused a drought by cooling the surface of the sea around Tuvalu. A state of emergency was declared on 28 September 2011; with rationing of fresh-water on the islands of Funafuti and Nukulaelae. Households on Funafuti and Nukulaelae were restricted to two buckets of fresh water per day (40 litres).

What is the usual amount of rainfall per month on Tuvalu?
Answer: 200 to 400 mm

The Bronx is almost entirely situated on the North American mainland. The Hudson River separates the Bronx on the west from Alpine, Tenafly and Englewood Cliffs in Bergen County, New Jersey; the Harlem River separates it from the island of Manhattan to the southwest; the East River separates it from Queens to the southeast; and to the east, Long Island Sound separates it from Nassau County in western Long Island. Directly north of the Bronx are (from west to east) the adjoining Westchester County communities of Yonkers, Mount Vernon, Pelham Manor and New Rochelle. (There is also a short southern land boundary with Marble Hill in the Borough of Manhattan, over the filled-in former course of the Spuyten Duyvil Creek. Marble Hill's postal ZIP code, telephonic Area Code and fire service, however, are shared with the Bronx and not Manhattan.)

What's on the other side of the East River from the Bronx?
Answer: Queens

Between 2000 and 2004 an average of 478 crimes were reported each day in Mexico City; however, the actual crime rate is thought to be much higher "since most people are reluctant to report crime". Under policies enacted by Mayor Marcelo Ebrard between 2009 and 2011, Mexico City underwent a major security upgrade with violent and petty crime rates both falling significantly despite the rise in violent crime in other parts of the country. Some of the policies enacted included the installation of 11,000 security cameras around the city and a very large expansion of the police force. Mexico City has one of the world's highest police officer-to-resident ratios, with one uniformed officer per 100 citizens.

What is one way the city tried to combat crime?
Answer:
installation of 11,000 security cameras
