Question

Savion listed the steps involved when nuclear power plants generate electricity.

Nuclear reaction occurs.
Nuclear energy is converted to radiant and thermal energy.
Heat is used to generate steam.
Light and heat are released.
Steam turns turbines.
Mechanical energy is converted to electrical energy.
Which best explains how to correct Savion’s error?

In step 2, change “radiant and thermal ” to “chemical and mechanical.”
Reorder the steps so that step 4 appears before step 3.
Reorder the steps so that step 6 appears before step 5.
In step 6, change “mechanical” to “thermal.”

Answer 1

Reorder the steps so that step 4 appears before step 3.

Explanation: Light and heat are released as part of (or immediately after) the nuclear reaction/radiant-and-thermal energy release, and that occurs before the released heat is used to generate steam. The other options change incorrect energy types or reverse the turbine/electric conversion order.
