Classifying economic sectors

Steps:

• Recall that the primary sector involves extracting raw materials, like farming or mining.
• The secondary sector covers manufacturing and processing goods from raw materials.
• The tertiary sector provides services to people and businesses, such as advice or retail.
• Match each option to its sector based on these definitions.

Why B is correct:

• Giving legal advice is a professional service, fitting the tertiary sector's focus on intangible services per economic classification systems.

Why the others are wrong:

• A is secondary, as assembling computers is manufacturing.
• C is primary, as harvesting grain extracts natural resources.
• D is secondary, as making bread processes ingredients into goods.

Final answer: B
