However, he can die as well. And this only means he is insignificant but only seeing the number of people suffering from it.

Explanation:

The answer is self explanatory.

Capable of being sacrificed

Explanation:

Context clues is a literary strategy where authors use their own text to give a hint about the meaning of a little-known word to the reader. In the case shown in the text above, the author left contextual clues to show the meaning of the word "expendable". This is because one of the characters in the text states that he does not mind going to a region that is the center of an Ebola epidemic, because it is expendable.

Ebola is a contagious and deadly disease, which is why, according to the context, we can see that the word "expendable" refers to something that is capable of being sacrificed.
