Questions 1-3 are about the following passage.

    The Civil War happened just as the art of photography was growing. Many people believe that photography had a big effect on the war. People were able to see images of their president, Abraham Lincoln. They were also able to have photographs of their sons, fathers, brothers, and husbands who fought or died in the war.

    Not only that, but many photographs of battlefields were shown in galleries in New York and Washington D.C. These photographs made people understand just how terrible the war was. The pictures show piles of dead bodies in empty fields.

    Army generals also used photographers as part of their staff. They sent photographers to take pictures of enemy areas and bases. They took pictures of roads, railroads, and bridges so that they could have information about what everything looked like. They wanted to have information so that they could win the war. The war ended in 1865, but we still have the pictures. The photos from the battles of Antietam and Gettysburg are particularly sad. Even today, they make us remember the horrors of war.
