Conca brings in different media information. He brings in a second medium into the mix to try to reach the audience from a different point of view. It does use several modes like linguistic and gestural. He uses words that can be quite subjective like "believed" or "intelligible". And does leave a link to the other media, to connect issue of similar subject to another point of view.

Conca is showing that all forms of multimodal communication must be used to get the maximum effect for the maximum amount of time. The better organized it is for the reader to understand the message.

Again showing the importance of linguistic modes of communication by presenting multiple languages on information it allows for a more significant chance that it will be understood by a larger demographic.

Showing signs of danger that are only prevalent in our time will not work. Conca is suggesting something further than what can written or what can be shown. The message has to present some aura around it to make it more intimidating when giving off cautions. This Aural mode of thinking can come from take elements from both visual and linguistic modes to create a more emphasis to the message someone is trying to portray.

Conca brings a very interesting point to the matter, from the context of the article the reader knows that it's referring to the nuclear danger zones that people should not enter and have clear markings warning them. But Conca suggest that how will people understand the phrase and how will they interpret it? "STAY OUT!" can mean several things it could be someone's land or secured property by the government. Without the context of linguistic modal text ideas and message can be understood in a risky way.
