网考网解析：
It makes no difference how many students took the test nor how many were boys and how many were girls. More than half the boys and more than half the girls scored over 90, so more than half of all the grades were over 90. Column A is greater. **Use TACTIC 2, Chapter 12. Assume 7 boys and 11 girls took the exam. Then 11 students (4 boys and 7 girls) got over 90 and the other 7 got 90 or less. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
