Semantic memory is the part of our memory. Semantic memories are all about the facts that we all gather in our life when we all were young. these are the memories that are not related to our emotional or personal experience.
There are some semantic memories such as:
It is to be known that grass is green.
It is to be known that how scissors work.
To recognize the color of the pencil, pen, etc.
To know how to use a cell phone.
Thus here in the above context, Shelly has been used semantic memory in which she gets information about facts such as the president of the United States.
