How many main old industries were identified?

• A. Three
• B. Four
• C. Five
• D. Six

Answer: (B)

The main idea here is to identify how many categories the passage calls the main old industries. The text groups the traditional economy into four distinct sectors—typically coal mining, iron and steel, textiles, and shipbuilding—each presented as its own major area. By listing these four as the core old industries, the author makes four the number to count. So the correct choice is the one that reflects four. If you looked for three, five, or six, you’d be counting more or fewer categories than the passage actually names, which would miss how the author frames the traditional economy.
