Show answer & explanation
Correct answer: A
Concept
A pie-chart share converts to an absolute amount by multiplying the total by the share written as a fraction of 100. For combined sectors, first add their percentage shares, then apply the combined share to the total.
Application
Add the two sector shares: 35% + 30% = 65%.
Convert the combined percentage to a decimal: 65% = 65/100 = 0.65.
Multiply by the total emission: 0.65 × 5 mmt = 3.25 mmt.
Cross-check
Compute the sectors separately: 35% of 5 mmt is 1.75 mmt and 30% of 5 mmt is 1.50 mmt; their sum is 3.25 mmt.
Result
The combined absolute CO2 emission is 3.25 mmt.
