Which data display best shows a comparison of advantages and disadvantages for wind farms using two columns?

• A. Two-column chart listing advantages and disadvantages
• B. Venn diagram
• C. Pie chart
• D. Line graph

Answer: (B)

When you want to compare what wind farms do well with what they don’t, a layout that puts pros and cons side by side is the clearest. A two-column chart that lists advantages on one side and disadvantages on the other lets you see each point next to its counterpart, so you can weigh trade-offs like cost, environmental impact, energy output, maintenance, and land use at a glance. The other formats don’t show this kind direct, side-by-side comparison: a Venn diagram emphasizes overlaps between groups, not a simple list of pros and cons; a pie chart breaks a whole into parts, not a set of separate advantages and disadvantages; and a line graph shows how something changes over time, which isn’t the goal here. So the two-column chart is the most effective for this purpose.
