A state agency evaluates the safety of heavy metal concentrations in soil. The table 1 lists the limits that are considered acceptable. Levels that are higher than the ones in the table could harm human health. So, land must be tested for heavy metals before houses are built. If any levels are too high, then a developer must clean up the soil before building. A developer wants to build a neighborhood on a site where a car manufacturing plant used to be located. He takes a sample of soil from the site and has it tested. The results are shown in the table 2.
Based on the results, the developer decided not to clean up the site before building. Do the data support this decision?
(71% WRONG)
29No, because one level is above the acceptable limit.
Yes, because all levels are below the acceptable limits.
No, because two levels are above the acceptable limits.
Yes, because only one level is above the acceptable limit.
