Ahistorian wants to compare the causes of death in the people of particular civilization. she wants to show each cause of death as a percentage to indicate the largest cause of death. which form of visual representation of data is best suited for this task ?

I think a pie chart because if she wants to use the whole causes of deaths as percentages and if the answers are either a bar graph, line graph, pie chart, diagram, or map then a bar graph and line graph show how many deaths over time. Diagram and map, kinda just show where and how often the deaths were. So I went with pie chart and i'll let you know if it says it was correct or not.

It is pie chart. :)

d) iowa i believe is the answer
