Questions: Which graphs present the same data as the infographic's graph, thus allowing the same conclusions to be drawn?

Solution Steps

The infographic's graph is a pie chart showing the elements in the human body as a percentage of total mass. The elements and their percentages are:

• Oxygen: 65%
• Carbon: 18%
• Hydrogen: 10%
• Nitrogen: 3%
• Other elements (including Ca, P, K, S, Na, Cl): 4%

There are three bar graphs below the pie chart. We need to determine which of these bar graphs present the same data as the pie chart.

• The first bar graph shows the elements in the human body with the same percentages as the pie chart: Oxygen (65%), Carbon (18%), Hydrogen (10%), Nitrogen (3%), and Other elements (4%).
• The second bar graph shows the big four elements (Oxygen, Carbon, Hydrogen, Nitrogen) as 96% and other elements as 4%. This does not match the pie chart exactly.
• The third bar graph shows a single bar for elements in the human body, which does not provide the same detailed breakdown as the pie chart.
