Question 5: 70% of people live in the countryside. A the countryside B 70% of C 70% of people

The correct answer is **C: 70% of people**.<br /><br />The question is asking for the complete subject of the sentence. "70%" is a percentage, and "of people" specifies what the percentage refers to. Together, "70% of people" forms the subject of the sentence, indicating who lives in the countryside. Option A only provides a location, and option B is an incomplete phrase.<br />
