Answer: D. a simile that is long and makes detailed comparisons
Explanation:
An epic simile is a simile that extends over several lines and often compares two unlike things. It is also known as Homeric simile, because Homer was the first author to use it in his epics. It is typically used in epic poetry as a decoration, or a means to demonstrate a character's courage. Epic simile is recognized by the frequent use of comparative structures with words such as: <em>as, so, like </em>or<em> just so.</em>
Cavaliers is the group who supported the king.
A pod is a shell that holds a plant's seeds (such as peas). When these pods become ripe, they burst open, releasing the seeds to the ground.
The comparison implies that the children were desperate to go outside, so that when the door was open, they burst out desperately and suddenly, just like the peas of a pod.
