Final answer:
Lin's presentation about road safety can benefit from the inclusion of universal road signs and the use of signpost language to guide the audience. Explaining the installation of traffic signals with a cause-and-effect approach can further enhance understanding and support for safety measures.
Step-by-step explanation:
When Lin is making a presentation about road safety, it's important to recognize that signage is a vital component. Road signs serve to direct drivers, warn them of potential dangers, and inform them of local regulations such as speed limits. Some road signs are universal, meaning they are recognized across different regions and cultures, which can make a presentation resonate with a diverse audience. For instance, a stop sign's octagonal shape and bold red color are recognized worldwide.
Incorporating images of road signs into a presentation about road safety can help clarify the points being made, such as advocating for reassessing speed limits or highlighting pedestrian safety concerns. For a more effective presentation, Lin could use signpost language to clearly guide the audience through the content, analogous to how road signs guide drivers.
Discussing the reasons for installing traffic signals at dangerous intersections is another way to address road safety. One could explain the cause and effect, such as increased accidents or pedestrian risks, leading to the decision to install a traffic signal. This approach not only informs the audience but also helps them understand the rationale behind road safety measures.
