Final answer:
The Civil War led to greater economic independence for women as they filled roles left by men who went to war. They ran businesses, worked in industries, and served in medical capacities, but did not gain expanded voting rights or significant combat roles from the war.
Step-by-step explanation:
The Civil War is responsible for various changes in women's lives. Among the options given, the change that accurately reflects the impact of the Civil War on women's lives is Option 3: Greater economic independence. During this time, with hundreds of thousands of men joining the army, women had to take over many roles traditionally held by men. This included running farms, businesses, and even working in factories. They also served in capacities such as nurses, and in some rare cases, disguised themselves to engage in combat roles. However, it's important to note that the Civil War did not bring about expanded voting rights for women; this occurred later with the passage of the Nineteenth Amendment in 1920. The war also did not lead to reduced access to education for women or significantly increased participation in actual combat roles.
While many women did indeed perform invaluable work during the war, their roles were primarily supportive, and they were typically kept from formal combat positions. Economic independence was the greatest impact, as women found themselves in positions that had previously been unavailable to them, leading to an expanded workforce participation that would have lasting effects on women's roles in society.
