Question

read this sentence from the text. in this sentence, the word \preserved\ is used to mean a saved for future use b kept in its original condition c used for a certain purpose d broken apart waste in modern landfills is well preserved because it decomposes at a slow rate.

Explanation:

To determine the meaning of "preserved" in the sentence "Waste in modern landfills is well preserved because it decomposes at a slow rate", we analyze each option:

• Option A: "Saved for future use" doesn't fit as the context is about the waste's condition, not saving it for later use.
• Option B: "Kept in its original condition" makes sense. Since the waste decomposes slowly, it remains in a relatively original state, so "preserved" here means kept as it was.
• Option C: "Used for a certain purpose" is irrelevant to the context of the waste's state in landfills.
• Option D: "Broken apart" is the opposite of what "preserved" would mean, as decomposition being slow means it's not breaking apart quickly.

Answer:

B. kept in its original condition
