Uranus

 Uranus is the seventh planet from the Sun. Its name is a reference to Uranus, the Greek god of the sky, who was the great-grandfather of Ares, grandfather of Zeus, and father of Cronus, according to Greek mythology. It possesses the Solar System's third-largest planetary radius and fourth-largest planetary mass. Uranus and Neptune are chemically similar, although their bulk chemical compositions vary from those of Jupiter and Saturn, the bigger gas giants. As a result, Uranus and Neptune are often referred to as "ice giants" to differentiate them from the other large planets.

Uranus, like the other classical planets, is visible to the naked eye, but due to its dimness and slow orbit, it was never identified as a planet by ancient observers. On March 13, 1781, Sir William Herschel made the first observation of Uranus, which led to its identification as a planet, extending the Solar System's recognized limits for the first time in history and making Uranus the first planet designated as such using a telescope.

Uranus features a ring system, a magnetosphere, and multiple moons, much like the other major planets. Because its axis of spin is slanted sideways, almost into the plane of its solar orbit, the Uranian system has a peculiar configuration. As a result, its north and south poles are located where the equators of most other planets are located. In 1986, photographs from the Voyager 2 spacecraft revealed Uranus to be a nearly featureless planet in visible light, lacking the cloud bands and storms seen on other big planets. The only spaceship to visit the planet is Voyager 2. As Uranus reached its equinox in 2007, observations from Earth revealed seasonal changes and increasing weather activity.

Manfred von Richthofen

 Manfred von Richthofen, famously known as the "Red Baron," was a legendary fighter pilot in the German Air Force during World War I. Revered as the war's "ace of aces," he is officially credited with an astonishing 80 air combat victories before his untimely death in 1918. His Great Dane, “Moritz,” was more than just a loyal companion—he frequently accompanied the Red Baron on his daring missions, including during some of his most celebrated aerial victories, earning the affectionate title of the Red Baron's "partner in flight."

President/Vice President Surnames

 Bill Clinton and George Clinton shared the surname Clinton while serving in the roles of President and Vice President, respectively. Bill Clinton served as the 42nd President of the United States, while George Clinton served as Vice President under both Thomas Jefferson and James Madison. While the surname Johnson was not listed as a multiple-choice option, it would also have been a correct answer. The surname Johnson was shared by Andrew Johnson, the 17th President, and Lyndon B. Johnson, who served as Vice President under John F. Kennedy before becoming the 36th President.

Petra, Jordan

 Petra is a historic and archaeological city in southern Jordan. It is located next to the Jabal Al-Madbah mountain, in a basin surrounded by mountains that constitute the eastern side of the Arabah valley, which runs from the Dead Sea to the Gulf of Aqaba. Petra has been inhabited since at least 7000 BC, and the Nabataeans may have resided in what would become their kingdom's capital city as early as the 4th century BC. Only evidence of Nabataean presence has been uncovered, going back to the second century BC, when Petra had been their city. The Nabataeans were nomadic Arabs who established Petra as a key regional economic centre because of its closeness to the incense trade routes.

The Nabataeans made a lot of money through commerce, and Petra became the center of their prosperity. Unlike their attackers, the Nabataeans were used to living in desolate deserts and were able to withstand invasions by taking use of the area's rugged environment. Rainwater gathering, agriculture, and stone sculpting were among their specialties. Petra reached its height in the first century AD, when the magnificent Al-Khazneh edifice – thought to be the tomb of Nabataean king Aretas IV – was built, and its population reached 20,000 people.

Although the Nabataean kingdom became a Roman Empire client state in the first century BC, it did not lose its independence until 106 AD. The Romans conquered Petra and acquired Nabataea, renaming it Arabia Petraea. Petra's significance waned when sea trade routes established, and many of its buildings were damaged by an earthquake in 363. Several Christian churches were erected during the Byzantine period, but the city continued to decay, and by the early Islamic era, it had been abandoned save for a few nomads. It remained undiscovered until Johann Ludwig Burckhardt uncovered it in 1812.

Petra was declared a UNESCO World Heritage Site on December 6, 1985. It was also designated one of the New7Wonders of the World in a public survey in 2007. In August 2007, the Petra Archaeological Park (PAP) was established as a separate legal organization to oversee the site's administration. The Bidouls are a Bedouin tribe whose cultural legacy and traditional skills were declared intangible cultural heritage by UNESCO in 2005 and inscription in 2008.

George W. Bush

 The last time a Republican presidential candidate won the popular vote prior to this year's election was in 2004. During that election, President George W. Bush secured a second term by defeating Democratic challenger John Kerry. Bush received approximately 62 million votes, which accounted for 50.7% of the total votes cast, making it the first time since 1988 that a Republican candidate achieved a majority in the popular vote. At the time, Bush received the most popular votes in history, a record which would later be surpassed in the 2008 presidential election.
