Problem: In February 1975, Margaret Thatcher was elected leader of the British Conservative Party. The Institute of Economic Affairs arranged a meeting between Hayek and Thatcher in London soon after. During Thatcher's only visit to the Conservative Research Department in the summer of 1975, a speaker had prepared a paper on why the "middle way" was the pragmatic path the Conservative Party should take, avoiding the extremes of left and right. Before he had finished, Thatcher "reached into her briefcase and took out a book. It was Hayek's The Constitution of Liberty. Interrupting our pragmatist, she held the book up for all of us to see. 'This', she said sternly, 'is what we believe', and banged Hayek down on the table".
Which of Hayek's works did Thatcher produce at the Conservative Research Department?
The answer is the following: The Constitution of Liberty

Problem: The initial cost of an incandescent bulb is small compared to the cost of the energy it uses over its lifetime. Incandescent bulbs have a shorter life than most other lighting, an important factor if replacement is inconvenient or expensive. Some types of lamp, including incandescent and fluorescent, emit less light as they age; this may be an inconvenience, or may reduce effective lifetime due to lamp replacement before total failure. A comparison of incandescent lamp operating cost with other light sources must include illumination requirements, cost of the lamp and labor cost to replace lamps (taking into account effective lamp lifetime), cost of electricity used, effect of lamp operation on heating and air conditioning systems. When used for lighting in houses and commercial buildings, the energy lost to heat can significantly increase the energy required by a building's air conditioning system. During the heating season heat produced by the bulbs is not wasted, although in most cases it is more cost effective to obtain heat from the heating system. Regardless, over the course of a year a more efficient lighting system saves energy in nearly all climates.
Do incandescent lights have a longer or shorter life than other lighting sources?
The answer is the following: shorter

Problem: In March 1861, Victoria's mother died, with Victoria at her side. Through reading her mother's papers, Victoria discovered that her mother had loved her deeply; she was heart-broken, and blamed Conroy and Lehzen for "wickedly" estranging her from her mother. To relieve his wife during her intense and deep grief, Albert took on most of her duties, despite being ill himself with chronic stomach trouble. In August, Victoria and Albert visited their son, the Prince of Wales, who was attending army manoeuvres near Dublin, and spent a few days holidaying in Killarney. In November, Albert was made aware of gossip that his son had slept with an actress in Ireland. Appalled, Albert travelled to Cambridge, where his son was studying, to confront him. By the beginning of December, Albert was very unwell. He was diagnosed with typhoid fever by William Jenner, and died on 14 December 1861. Victoria was devastated. She blamed her husband's death on worry over the Prince of Wales's philandering. He had been "killed by that dreadful business", she said. She entered a state of mourning and wore black for the remainder of her life. She avoided public appearances, and rarely set foot in London in the following years. Her seclusion earned her the nickname "widow of Windsor".
During which year did Victoria's mother die?
The answer is the following: 1861

Problem: The rising population has resulted in an increased demand on fish stocks, which are under stress; although the creation of the Funafuti Conservation Area has provided a fishing exclusion area to help sustain the fish population across the Funafuti lagoon. Population pressure on the resources of Funafuti and inadequate sanitation systems have resulted in pollution. The Waste Operations and Services Act of 2009 provides the legal framework for waste management and pollution control projects funded by the European Union directed at organic waste composting in eco-sanitation systems. The Environment Protection (Litter and Waste Control) Regulation 2013 is intended to improve the management of the importation of non-biodegradable materials. In Tuvalu plastic waste is a problem as much imported food and other commodities are supplied in plastic containers or packaging.
What has been formed to protect the fish stocks in Tuvalu Lagoon?
The answer is the following:
Funafuti Conservation Area
