Final answer:
The word in the passage that means the same as 'use up' is 'consumption', as it refers to the act of using resources or goods, often leading to their depletion. The correct answer is option 2.
Step-by-step explanation:
The word in the passage that means the same as use up is consumption. The word 'remains' generally refers to what is left over after other parts have been removed, used, or destroyed. 'Indelible' describes something that cannot be removed or washed away. 'Materials' are the substances or objects that are needed to do something or create something. Therefore, the term that aligns with the meaning of 'use up' is 'consumption,' as it involves using resources or goods to the point where they may be depleted.
