Which dance originated in Buenos Aires and spread to America and Europe in the early 20th century?

• A. Waltz
• B. Flamenco
• C. Tango
• D. Salsa

Answer: (C)

The main idea here is identifying a dance that began in Buenos Aires and then spread to America and Europe in the early 20th century. That dance is tango. It started in Buenos Aires in the late 1800s, born from a blend of influences in the port city and barrios, and its distinctive close embrace and dramatic, sultry steps helped it stand out. As performers and musicians took tango abroad, it quickly gained popularity in Europe and North America, especially during the 1910s and 1920s.

Waltz comes from central Europe and was already popular well before the 20th century, flamenco has roots in Spain, and salsa developed later in the Caribbean and the United States, not specifically tied to Buenos Aires in its origin.
