Question 1 Report
The bar chart shows the volume of carbon dioxide, in arbitrary units, released by burning equal masses of four fuels. Which fuel, shown by bar S, releases the least carbon dioxide?
Answer Details
On a bar chart the height of each bar shows the size of the quantity, so the shortest bar means the smallest release of carbon dioxide.
Reading the chart against the same axis, the first bar is the tallest, the third bar is next, then the second, and bar S is clearly the shortest of the four, standing at roughly a third of the height of the tallest. The fuel represented by bar S therefore releases the least carbon dioxide for the same mass burned, which makes it the cleanest of the four in this respect. The mistake to avoid is picking the tallest bar, which answers the opposite question by giving the fuel that releases the most.
