[单项选择]The military aspect of the United States Civil War has always attracted the most attention from scholars. The roar of gunfire, the massed movements of uniformed men, the shrill of bugles, and the drama of hand-to-hand combat have fascinated students of warfare for a century. Behind the lines, however, life was less spectacular. It was the story of back-breaking labor to provide the fighting men with food and arms, of nerve-tingling uncertainty about the course of national events, of heartbreak over sons or brothers or husbands lost in battle. If the men on the firing line won the victories, the means to those victories were forged on the home front.
Never in the nation’s history hid Americans worked harder for victory than in the Civil War. Northerners and Southerners alike threw themselves into the task of supplying their respective armies. Both governments made tremendous demands upon civilians and, in general, received willing cooperation.

[单项选择] In the United States during 1992, any family of four with an annual cash income of less than $14,335 (before taxes) was considered poor. The dollar amount was called the poverty line, an economic measuring rod devised in 1964. The line was set at three times the amount needed to provide the cheapest nutritionally balanced diet. The poverty line is adjusted annually for inflation. While the poverty line in the United States was more than $14,000, the average annual per-person income in Bangladesh was $200, in Ethiopia $130, in Haiti $340, and in Mali $265. Anyone in those nations with an income of $14,000 would be considered wealthy. During the Great Depression in the United States, when half the population was considered poor, a family with an income at the 1992 poverty line could afford to buy a house, a car, clothing and food. The reality of poverty varies with location and social and political conditions. Poverty basically means a lack of, or an insufficient amount of,
A. you are out of a job
