Passage 4
Questions 36 to 40 are based on the following passage.
Readers of novels like Jane Austen’s Pride and Prejudice will know that in former times marriage among wealthy families were arranged by the girl’s parents, that is,it was the parents’ duty to find a suitable husband for their daughter,preferably a rich one,and by skillful encouragement to lead him eventually to ask their permission to marry her.Until that time,the girl was protected and maintained in the parents’ home,and the financial relief of getting rid of her could be seen in their giving the newly married pair a sum of money called a dowry.It is very different today.Most girls of today get a job when they leave school and become financially independent before their marriage.This has had two results.A girl chooses her own husband,and she gets no dowry.
