card with her into the higher level?

Nancy Jaax is a veterinary pathologist in United States. She was the one to bring out the cure for the most infectious Ebola virus.

Explanation:

Based on this true story, Richard Preston wrote a novel name ‘The Hot Zone’ which describes how Nancy worked on this disease, and how it finally resulted in a success.

The thing about why Nancy Jaax couldn’t bring her security card into higher level is a totally different story. It might have possibly got to do  with the United States service rules and regulations.

(you didn't attach a copy of the poem, but i'm answering as best as i can)

since a simile compares two unlike things using like or as, it kind of gives an item the ability to do something it can't.

example: "the player was like a tiger on the field"

in this sentence, the simile conveys the idea that the player was fast and strong, like a tiger.
