CONTAMINATION DRILL case: powder spill produces evidence from surface activity. Which option best answers the objective "Explain nuclear stability using neutron-proton ratio." for Nuclear instability, while reaching the conclusion about decontamination route?.
- A.nuc-125-contamination-drill: Link powder spill to surface activity and conclude decontamination route for Nuclear instability.
- B.nuc-125-contamination-drill: Ignore surface activity and answer with an unrelated Radioactivity recall phrase.
- C.nuc-125-contamination-drill: Swap the required nuclear distinction and claim decontamination route without evidence.
- D.nuc-125-contamination-drill: Use a calculation label only, without applying explain nuclear stability using neutron-proton ratio..
Model answer
What a good answer should say
- The correct option is nuc-125-contamination-drill: Link powder spill to surface activity and conclude decontamination route for Nuclear instability.
Explanation
Why this works
It is correct because the contamination drill context uses surface activity to support explain nuclear stability using neutron-proton ratio. in Nuclear instability.
The distractors fail because they either ignore the evidence, swap a nuclear concept boundary, or give a label without the required A-Level Physics reasoning.
