7 - 8. Guard rails were introduced on British roads to improve the _______ of
pedestrians, while ensuring that the movement of _______ is not disrupted.
Key words: Guard rails, improve, pedestrians, movement, not disrupted
In paragraph E, the guard rails are described as “an engineering solution to pedestrian
safety …”; “pedestrian safety” could be rephrased as “the safety of pedestrians”.
Therefore, “safety” is the answer for gap 7.
Moreover, the guard rails were based on models that “prioritise the smooth flow of
traffic”, where the “smooth flow” could be understood as “movement” that is “not
disrupted”, meaning that it also ensures the undisrupted movement of traffic. Thus,
“traffic” should be filled in gap 8
movement = flow
→ Answer: safety – traffic.
