Specification 4.6.3.1 · Paper 2
A well-supported scientific explanation that accounts for observations and can be tested against evidence.
Paper 1 (Foundation), Paper 2 (Foundation), Paper 3 (Higher), Paper 4 (Higher)
A well-tested explanation that accounts for a wide range of observations and can guide further investigation; it is not simply a guess.
A is not an unsupported guess: it is an explanation tested against observations and used to guide further investigation. Evolution explains how living populations have changed; it does not claim to explain how life first began.
Justify a hypothesis or prediction with relevant scientific theory or a plausible mechanism, rather than writing an unsupported guess.
Do not describe a scientific theory as a guess. It is a broad explanation that has been tested and used successfully.
