Question

1. in a nuclear reactor, lowering control rods will result in ____.

○ reduced energy output
○ meltdown
○ increased temperature
○ more free neutrons

Explanation:

Control rods in nuclear reactors absorb neutrons to slow or stop fission reactions. Lowering them increases neutron absorption, reducing the chain reaction rate, which decreases energy output. This prevents overheating/meltdown and reduces free neutrons.

Answer:

A. reduced energy output
