Question

jorge is testing the effect of lead on child development. based on his observations, he finds that the longer the children are exposed to lead - based paint, the higher the chance becomes that the children may develop behavioral problems. he has done repeated experiments, and his results are similar to the results of many other scientists. why is this scenario considered a theory rather than a hypothesis? it is a testable scenario. it is based on prior knowledge. it is a well - tested explanation. it is a factual statement.

Explanation:

A hypothesis is a proposed explanation that is testable but not yet proven. A theory, on the other hand, is a well - tested explanation that has been supported by multiple experiments and observations. In this scenario, Jorge has done repeated experiments and his results are similar to those of many other scientists. This indicates that the explanation (the relationship between lead exposure and behavioral problems in children) has been well - tested. Just being testable (as in the first option) is a characteristic of a hypothesis as well. Being based on prior knowledge (second option) is also common for hypotheses. A factual statement (fourth option) is too simplistic as a theory is a more comprehensive and well - supported explanation compared to a simple fact.

Answer:

It is a well - tested explanation.
