题型：单项选择题

By the year 1869 when the first transcontinental railroad was finished, over 350,000 pioneers had taken the Oregon Trail to head west and start a new life, which is known as the Gold Rush Period in American history. Many of these were women and most were accompanied by children.

Before heading west, many women often spent their day doing nothing more than visiting, needlework, and the occasional gardening of flowers. Others were not from as wealthy families and had to work alongside their men as laborers. Neither type was in most cases prepared for the hardships that lay ahead.

Once they did reach their destination, the work was far from over. A house would need to be built. Women quickly learned to use all kinds of tools right alongside their husbands. At the first sign of spring, a garden would need to be planted. Pioneer women also had to deal with dangerous wild animals, including bears and lions. Indians were also a concern, and some did fall to their deaths by the Indians’ hand. Where were the men when all this was being done? Working the fields and mining were the two most usual occupations. Their remaining work, which there was plenty of, fell to the women and the oldest children if there were any.

Women who headed west learned quickly that there was much more to life than teas and visiting. They had no choice but to struggle for survival. This was their life.
