Question

which of the following is not a step they would take to study or explain the origins of life on earth?
make claims based on empirical evidence they collected through experimentation.
run a single experimental trial to simulate early conditions on the earth.
form and test hypotheses about natural processes that could account for the formation of the building blocks of life.
review the empirical evidence collected by other scientists before forming a hypothesis.

Explanation:

In scientific studies, especially complex ones like the origins of life, a single - experimental trial is not sufficient. Multiple trials are needed to ensure reliability and validity of results. Making claims based on empirical evidence, forming and testing hypotheses, and reviewing prior evidence are standard scientific steps.

Answer:

Run a single experimental trial to simulate early conditions on the Earth.
