Answer:
She floated around the room so easily she
could be Phileas Fogg - Allusion
She floated around the room like a balloon - Simile
She floated around the room, moving in no
specific direction - Metaphor.
Explanation:
A similar is used when comparing something to another. A sentence bearing a simile is identified by the presence of "like" or "as"
This is shown in the answer above where a lady's movement was compared to a balloon floating.
A metaphor is also used in comparison but this time directly. The quality given to the subject may not necessarily be true.
In the example above, the lady was described as floating "floated around the room..." Also notice that people do not necessarily float but in this case her movement was directly described as floating.
Allusion is used to make reference to objects, persons, places or even events.
In the example above, the ladies movement was not only described as floating but Phileas Fogg was used in reference to it.
