Question
- A. It helps to refine and improve scientific theories
- B. It allows scientists to ignore conflicting evidence
- C. It ensures that all predictions are always correct
- D. It prevents any changes to established scientific ideas
Answer
The correct option is It helps to refine and improve scientific theories.
Explanation
The correct option is It helps to refine and improve scientific theories. It helps to refine and improve scientific theories is correct because it directly supports the approved learning objective to explain how testing predictions can support or refute scientific ideas. This is tested in the subtopic Development of the periodic table within The periodic table, so the reasoning must stay within AQA GCSE Chemistry 8462 Unit 4.1. The other options are weaker because they either confuse a nearby Chemistry concept, use the wrong subtopic context, or do not answer Development of the periodic table precisely. Repair marker 88addd12 keeps this question distinct from adjacent atom, ion, isotope, group, period, and electronic-structure questions.
Common mistake
Misunderstanding Predictions

Emphasize that testing predictions can lead to either supporting or refuting scientific ideas, highlighting the importance of both outcomes in the scientific process.
