Select the option that best explains the information conveyed in the sentence Our school field is bigger than yours.

Analyze the question: The sentence "Our school field is bigger than yours" is a comparison. It tells us that our field has more size than your field. We need the option that says the same thing in a different way.

Concept: Comparatives like "bigger than" can be restated with "not as ... as" from the other side:

• "X is bigger than Y" = "Y is not as big as X"

Check each option:

• A. Your school is bigger than ours. This reverses the comparison. It also talks about the school, not the school field. Wrong.
• B. Your school is not bigger than ours. This talks about the school, not the field. It also only says yours is not bigger, which would still be true if the two were equal. Wrong.
• C. Our school field is as big as yours. This says the two fields are equal, but the original says ours is bigger. Wrong.
• D. Your school field is not as big as ours. This says your field is smaller than ours, which means ours is bigger. Correct.

Answer: D.

Tip: For comparison questions, check two things:

1. The subject: field, not school.
2. The direction: who is bigger.

Remember that "A is bigger than B" means "B is not as big as A."
