Which of the following is TRUE about Maria according to the text?

参考解析：

细节理解题。根据第二段和第三段最后一句“That dream was to finish school — something Maria had to give up at a young age when her father passed away—and she began to pursue it after quitting her job in September 2007. ”可知，在她父亲去世后她只是放弃了学业，直到2007年才放弃工作开始追逐梦想，故排除A项；根据第四段最后一句“With that kind of accomplishment, she started classes for the PSW Certificate program in September 2008. ”和第五段““Since I was used to working very long days, I decided to take some computer courses as well,” she says. “After all, you never know what kind of job is in your future, or what kind of changes technology will lead to.” ”可知她上计算机课是为了拿到PSW证书，因此是在拿到证书之前上的课，故排除C项；根据第六段“She also joined a volunteer program, Storefront Humber, a home-support service company that assists the elderly with meals and daily activities. ”可知，她只是参加了这个项目但并不是她本人组织的，故排除D项；根据第二段后两句“Unfortunately, she kept training plant managers without going anywhere. She knew that it was because she didn’t have any education. ”可知，她得不到晋升就是因为没有接受过教育，故选B。
