Answer:
Gio is suffering from B. the primacy effect.
Step-by-step explanation:
Primacy is the ability we have to remember the first information received or memorized. Since audiences usually have a fresh mind at the beginning of a speech, the primacy effect must be taken into consideration by public speakers. The correct and important information must be presented first in a way that catches people's attention. It can be restated at the end of the speech to combine the primacy effect with the recency one - the ability to remember what was seen last.
