In 1876, the key idea is identifying which invention is tied to that specific year and its impact on how industry and commerce operated. The telephone was patented by Alexander Graham Bell in 1876, a milestone that transformed everyday communication. Before this, long-distance talk was impractical; with the telephone, people and businesses could speak in real time across distances, speeding decision-making, coordinating work, and enabling new kinds of networks that powered industrial growth. Other options don’t fit the same year and impact. The Moon Landing happened in 1969, far beyond the Industrial Age. The printing press was invented much earlier and started a different wave of mass communication centuries prior. The typewriter emerged in the late 19th century and reshaped writing and offices, but the year most associated with a leap in direct voice communication is 1876, making the telephone the best match.
