a. It's the one【51】the teacher standing in the schoolroom door【52】goodbye to students for the summer and calling after them. "By the way, we won World War II. "

Even when they get the answers right, some are just guessing.

Unlike math or science, ignorance of history cannot be【57】connected to toss of international competitiveness. But it does affect our future【58】a democratic nation and as individuals.

The good news is that there is growing agreement on what is wrong with the【59】of history and what needs to be done to fix it. The steps are tentative (尝试性的)【60】yet to be felt in most classrooms.
