Final answer:
The third statement, 'S is greater than L', cannot be true if the first two statements are accepted as true because it would create a logical inconsistency with the given inequalities.
Step-by-step explanation:
The question presents three statements involving inequalities and asks whether the third statement can be true if the first two are true. We are given:
1. L is either greater than or equal to G.
2. S is either smaller than or equal to G.
3. S is greater than L.
If we accept that the first two statements are true, the third statement creates a logical inconsistency and, therefore, cannot be true. This is because if S ≤ G and L ≥ G, it is impossible for S to be greater than L without violating one of the first two conditions.
