Problem: San Diego:

The development of skyscrapers over 300 feet (91 m) in San Diego is attributed to the construction of the El Cortez Hotel in 1927, the tallest building in the city from 1927 to 1963. As time went on multiple buildings claimed the title of San Diego's tallest skyscraper, including the Union Bank of California Building and Symphony Towers. Currently the tallest building in San Diego is One America Plaza, standing 500 feet (150 m) tall, which was completed in 1991. The downtown skyline contains no super-talls, as a regulation put in place by the Federal Aviation Administration in the 1970s set a 500 feet (152 m) limit on the height of buildings due to the proximity of San Diego International Airport. An iconic description of the skyline includes its skyscrapers being compared to the tools of a toolbox.

Problem: Gene:

Prior to Mendel's work, the dominant theory of heredity was one of blending inheritance, which suggested that each parent contributed fluids to the fertilisation process and that the traits of the parents blended and mixed to produce the offspring. Charles Darwin developed a theory of inheritance he termed pangenesis, which used the term gemmule to describe hypothetical particles that would mix during reproduction. Although Mendel's work was largely unrecognized after its first publication in 1866, it was 'rediscovered' in 1900 by three European scientists, Hugo de Vries, Carl Correns, and Erich von Tschermak, who claimed to have reached similar conclusions in their own research.

What does the term gemmule describe?
---
A: hypothetical particles that would mix during reproduction


Problem: Florida:

In the closely contested 2000 election, the state played a pivotal role. Out of more than 5.8 million votes for the two main contenders Bush and Al Gore, around 500 votes separated the two candidates for the all-decisive Florida electoral votes that landed Bush the election win. Florida's felony disenfranchisement law is more severe than most European nations or other American states. A 2002 study in the American Sociological Review concluded that "if the state’s 827,000 disenfranchised felons had voted at the same rate as other Floridians, Democratic candidate Al Gore would have won Florida—and the presidency—by more than 80,000 votes."

A: Florida's felony disenfranchisement law is more severe than most European nations or other American states


Problem: Greeks:

The traditional Greek homelands have been the Greek peninsula and the Aegean Sea, the Southern Italy (Magna Graecia), the Black Sea, the Ionian coasts of Asia Minor and the islands of Cyprus and Sicily. In Plato's Phaidon, Socrates remarks, "we (Greeks) live around a sea like frogs around a pond" when describing to his friends the Greek cities of the Aegean. This image is attested by the map of the Old Greek Diaspora, which corresponded to the Greek world until the creation of the Greek state in 1832. The sea and trade were natural outlets for Greeks since the Greek peninsula is rocky and does not offer good prospects for agriculture.
