Answer:
The spokesperson did not follow the guideline of adapting the language to the public.
Step-by-step explanation:
When making a speech, it is essential that the speaker adapts the language used to the audience that will be listening to the lecture. In this case, the use of technical terms aligned with a specific type of profession, should only be used if the audience is part of that profession and knows all or most of these terms. It was exactly at this point that the spokesperson shown above failed, as he used technical terms for an audience that did not know them and did not understand what was being lectured.
