Question

read the text.
during world war i, british and american warships were at grave risk of german u - boat, or submarine, attacks. warships were easily visible against the surrounding ocean. so british artist norman wilkinson proposed a scheme to address this concern. rather than trying to hide the ships, he suggested painting them with bright shapes to confuse the enemy. more than a thousand ships were painted with bold patterns, including complex patterns on the bow and stern to confuse onlookers about which end was which. this technique, called dazzle camouflage, may not have actually confused the enemy, but it was effective in making the crews of the \dazzle boats\ feel safer.
which organizational structure does this text primarily use?
compare - contrast
problem - solution
sequential

The text first presents a problem: British and American warships were at high risk of submarine attacks in WWI because they were easily visible. Then it introduces the solution proposed by Norman Wilkinson: dazzle camouflage with bold patterns to confuse the enemy, along with notes on its effectiveness. This follows a problem-solution structure.
