Problem: Antenna (radio):

The majority of antenna designs are based on the resonance principle. This relies on the behaviour of moving electrons, which reflect off surfaces where the dielectric constant changes, in a fashion similar to the way light reflects when optical properties change. In these designs, the reflective surface is created by the end of a conductor, normally a thin metal wire or rod, which in the simplest case has a feed point at one end where it is connected to a transmission line. The conductor, or element, is aligned with the electrical field of the desired signal, normally meaning it is perpendicular to the line from the antenna to the source (or receiver in the case of a broadcast antenna).

What type of surface is formed by the tip of a conductor?
---
A: reflective

Problem: Gamal Abdel Nasser:

Nasser was greatly influenced by Egyptian nationalism, as espoused by politician Mustafa Kamel, poet Ahmed Shawqi, and his anti-colonialist instructor at the Royal Military Academy, Aziz al-Masri, to whom Nasser expressed his gratitude in a 1961 newspaper interview. He was especially influenced by Egyptian writer Tawfiq al-Hakim's novel Return of the Spirit, in which al-Hakim wrote that the Egyptian people were only in need of a "man in whom all their feelings and desires will be represented, and who will be for them a symbol of their objective". Nasser later credited the novel as his inspiration to launch the 1952 revolution.

Where did Nasser meet his anti-colonialist teacher?

A: Royal Military Academy

Problem: Melbourne:

Melbourne is also an important financial centre. Two of the big four banks, NAB and ANZ, are headquartered in Melbourne. The city has carved out a niche as Australia's leading centre for superannuation (pension) funds, with 40% of the total, and 65% of industry super-funds including the $109 billion-dollar Federal Government Future Fund. The city was rated 41st within the top 50 financial cities as surveyed by the MasterCard Worldwide Centers of Commerce Index (2008), second only to Sydney (12th) in Australia. Melbourne is Australia's second-largest industrial centre. It is the Australian base for a number of significant manufacturers including Boeing, truck-makers Kenworth and Iveco, Cadbury as well as Bombardier Transportation and Jayco, among many others. It is also home to a wide variety of other manufacturers, ranging from petrochemicals and pharmaceuticals to fashion garments, paper manufacturing and food processing. The south-eastern suburb of Scoresby is home to Nintendo's Australian headquarters. The city also boasts a research and development hub for Ford Australia, as well as a global design studio and technical centre for General Motors and Toyota respectively.

Melbourne is home to a research and development hub for which auto manufacturer?
---
A: Ford Australia

Problem: The Bronx:

The office of Borough President was created in the consolidation of 1898 to balance centralization with local authority. Each borough president had a powerful administrative role derived from having a vote on the New York City Board of Estimate, which was responsible for creating and approving the city's budget and proposals for land use. In 1989 the Supreme Court of the United States declared the Board of Estimate unconstitutional on the grounds that Brooklyn, the most populous borough, had no greater effective representation on the Board than Staten Island, the least populous borough, a violation of the Fourteenth Amendment's Equal Protection Clause pursuant to the high court's 1964 "one man, one vote" decision.

When was the Board of Estimate found unconstitutional?
---
A:
1989
