网考网参考答案：C
网考网解析：
The remaining three pumpkins must make up the difference between 150 kg and (20 pumpkins×6.5kg=)130 kg, so 20 kg. For three pumpkins to fill 20 kg, each must have a minimum mass of 2O kg divided by 3, which equals 6 2/3 kg, which is best expressed here as 6.67 kg. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
