Question

read the excerpt from the hot zone.
jerry was terribly keyed up. in the past he had lectured nancy on the dangers of working with ebola in a space suit, and now he was leading a team into an ebola hell. at the moment, he didnt care what happened to himself, personally. he was expendable, and he knew it.
based on context clues, what is the best definition of the word \expendable\?

• necessary to an operation
• knowledgeable about a topic
• capable of being sacrificed
• useless in a specific situation

Explanation:

The context states Jerry "didn't care what happened to himself, personally" while leading a team into an Ebola-contaminated area. This shows he viewed himself as someone whose safety could be given up for the mission, matching "capable of being sacrificed". Other options don’t fit: "necessary" contradicts his disregard for his own safety; "knowledgeable" and "useless" aren’t supported by the text.

Answer:

capable of being sacrificed
