Problem: 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 did a drought in 2011 cause on Funafuti?
The answer is the following: rationing of fresh-water

Problem: The first Grand Lodge, the Grand Lodge of London and Westminster (later called the Grand Lodge of England (GLE)), was founded on 24 June 1717, when four existing London Lodges met for a joint dinner. Many English Lodges joined the new regulatory body, which itself entered a period of self-publicity and expansion. However, many Lodges could not endorse changes which some Lodges of the GLE made to the ritual (they came to be known as the Moderns), and a few of these formed a rival Grand Lodge on 17 July 1751, which they called the "Antient Grand Lodge of England." These two Grand Lodges vied for supremacy until the Moderns promised to return to the ancient ritual. They united on 27 December 1813 to form the United Grand Lodge of England (UGLE).
The Ancient Grand Lodge of England was formed on what date?
The answer is the following: 17 July 1751
