Read the following passage, then choose the correct answer A. B, C or D. Women nowadays have more advantages than those in the past. For example, our great grandmothers were not allowed to go to school or go to work or even choose their own husband.

However, women living in our modern society have their problems, too. Today’s women work harder than their great grandmothers so that they can gain the balance between working life and family life.
