Which development reshaped American life in the late 20th century?

• A. Rise of computers and the Internet
• B. Invention of the telephone
• C. Discovery of electricity
• D. Invention of the printing press

Answer: (A)

The main idea this item tests is how digital technology changed everyday life in the late 20th century. The rise of computers and the Internet brought instant communication, vast access to information, and new ways of doing business, learning, and entertainment. In the 1980s, personal computers became common at home and in schools, making tasks like writing, budgeting, and data work easier and more affordable. In the 1990s, the World Wide Web, email, search engines, and online services connected people across distances in ways that transformed work, education, shopping, and culture. This shift created a more connected, information-driven society and helped spur new industries and global exchanges. Other options point to inventions that were major in earlier eras—telephones, electricity, and the printing press—but they occurred well before the late 20th century and did not redefine daily life in that period as profoundly as the rise of computers and the Internet did.
