Lead left in soil can be traced years past. Lead comes from car's waste tail gas. Soil nearby highway roads has higher trace of lead if more cars are on the highway. In 1970-1980, lead was added in car's gasoline, so we can conclude that the highway traffic was busy at that time if soil tested there contains more lead.

Commit which following mistake?

A. take one probable cause as the only cause for a result.
C. take what is necessary to a conclusion as what is sufficient to that conclusion.

It should be A.

The question stem takes vehicular emmisions as the only cause for lead present in soil.
