Cities and Cultural Landmarks

Shanghai has been the most populous city proper in the world for many years, with over 24 million residents within city limits. The ranking can vary based on whether counting city proper, urban area, or metropolitan area. By city proper population, Shanghai leads. Mumbai is India's most populous city but ranks lower globally.

Philadelphia served as the United States' first capital city from 1790 to 1800, before Washington D.C. It hosted the Continental Congress and the Constitutional Convention, making it the nation's first capital under the Constitution.

Harvard Business School is located in Boston, Massachusetts, specifically in the Harvard Square area of Cambridge (part of Greater Boston). It's part of Harvard University, the oldest institution of higher learning in the United States.

Las Vegas is renowned worldwide for its casinos and gambling industry. Los Angeles is known for entertainment, New York for finance and culture, and Miami for beaches and nightlife. None of the other cities are famous for casinos like Las Vegas.

Summersville is a town in Missouri. However, it's worth noting that there is also a Summersville in West Virginia. The question structure with 'All of these' as option B suggests a poorly constructed question, as multiple states likely have towns named Summersville.

LA Galaxy plays at Home Depot Centre (now Dignity Health Sports Park). Wrigley is a Chicago baseball stadium, Staples hosts Lakers/Kings, and Madison Square Garden is in New York.

Shanghai (misspelled as 'Sanghai' in the option) has been called 'Paris of the East', 'Queen of the Orient', and 'Pearl of the Orient' due to its colonial-era architecture, cosmopolitan culture, and economic importance. Hong Kong is sometimes called 'Pearl of the Orient' too, but the other two nicknames are specifically associated with Shanghai. Beijing is the capital and Yunan is a province, not a city.

Swami Vivekananda delivered his famous opening address 'Sisters and Brothers of America' (often quoted as 'My American brothers and sisters') at the Parliament of the World's Religions in Chicago in 1893. This speech introduced him to international acclaim.

The Royal Penthouse Suite at President Wilson Hotel in Geneva consistently ranks as the world's most expensive hotel suite, costing approximately $80,000-90,000 per night. It offers unparalleled views of Lake Geneva and the Alps.

Greenwich is the London borough where the Royal Observatory is located, and it marks the Prime Meridian (0° longitude) which is the reference point for Greenwich Mean Time (GMT) and international timekeeping. The observatory was established in 1675 and the Prime Meridian line runs through it. This is why world time is measured relative to Greenwich.

New York City's nickname 'The Big Apple' originated in the 1920s among jazz musicians, who called performing gigs 'the big time' or 'the big apple.' A 1970s tourism campaign popularized it globally.

Hartford, Connecticut has a law that makes it illegal for a husband to kiss his wife on Sundays. This is one of the many blue laws or outdated morality laws that exist in various American states. Houston, Los Angeles, and Memphis do not have such specific laws regarding Sunday kissing.

The Forbidden City in Beijing (then called Peking in English) was the imperial palace from the Ming dynasty (1420s) through the Qing dynasty (until 1912). The term 'Forbidden City' refers to how entry was restricted without emperor's permission. Hong Kong, Tokyo, and Honolulu were never capitals of Chinese dynasties. 'Peking' was the standard Western name for Beijing until the 1970s.

New York City was originally named New Amsterdam by the Dutch colonists who settled there in 1624. The British captured the colony in 1664 and renamed it New York in honor of the Duke of York. 'Big Apple' is a modern nickname, while 'East Side Ghetto' is a fictional distractor.

Rome is traditionally known as the 'City of Seven Hills' (Sette Colli in Italian), referring to the seven hills on which the ancient city was built: Palatine, Capitoline, Quirinal, Viminal, Esquiline, Caelian, and Aventine. Amsterdam, Berlin, and Paris do not share this nickname.
