听力原文： Barbara Sanders is a wife and the mother of two children, ages 2 and 4. Her husband, Tom, is an engineer and makes an excellent salary. Before Barbara had children, she worked as an architect for the government, designing government housing. She quitted her job when she became pregnant, but is now interested in returning to work. She's been offered an excellent job with the government. Her husband feels it's unnecessary for her to work since the family does not need the added income. He also thinks that a woman should stay home with her children. If Barbara feels the need to do socially important work, he thinks that she should do volunteer work one or two days a week. Barbara, on the other hand, has missed the excitement of her profession and does not feel she would be satisfied doing volunteer work. She would also like to have her own income, so she does not have to ask her husband for money whenever she wants to buy something. She does not think it's necessary to stay home every day with the children and she knows a very reliable babysitter who's willing to come to her house. Tom does not think a baby-sitter can replace a mother and thinks it's a bad idea for the children to spend so much time with someone who's not part of the family.

What was Barbara's profession before she had children？

A．Fashion designer.

B．Architect.

C．City planner.

D．Engineer.
