Comparing employment changes in economic sectors

Steps:

• Review year 1 data: primary sector employs 40% of workforce, secondary 30%.
• Review year 2 data: primary sector drops to 35%, secondary stays at 30%.
• Calculate changes: primary decreases by 5%, secondary shows 0% change.
• Determine distribution shift: primary falls, secondary unchanged.

Why B is correct:

• Option B matches the observed data where primary sector employment percentage declined while secondary remained constant, per standard economic sector definitions.

Why the others are wrong:

• A: Secondary sector did not rise; it stayed the same.
• C: Primary sector did not rise; it fell.
• D: Primary sector did not rise; it fell.

Final answer: B
