1 – Wrong
The word “would” suggests that improving staff levels will definitely reduce death rates. Also, this statement makes a casual link between staff levels and death rates.
2 – Wrong
If patients are unable to be saved in hospitals, then enhancing weekend provision of community and primary care services would be ineffective as well.
3 – Wrong
Patients should be admitted when they are seriously ill or injured. It does not matter whether the staff levels are low or high.
Since all statements are wrong, G is the answer.
