Помогите пожалуйста составить 8 разных вопросов по тексту!!! I always believed that if a woman made up her mind to marry a man, nothing but immediate escape could save him. And only once I knew a man who managed to escape. His name was Roger Charing. He fell in love with Ruth Barlow at first sight. When Roger told me that he wanted to marry her I wished him happiness. I considered her stupid but I couldn't tell Roger about it. Their marriage was fixed for the near future. Then, all of a sudden, he fell out of love. But he knew that she wouldn't release him if he simply asked her. So he thought of a plan. He didn't show Ruth that his attitude towards her had changed He sent her flowers; they dined together and went to the theatre together. They had made up their minds that they would be married as soon as they found a house that suited them. They visited house after house but always Roger found a fault that made the house unsuitable. They looked at hundreds of houses and Ruth felt worn-out. Once she said angrily, "If you can't find a house soon I won't marry you." "We are sure to find a proper house and in less than no time we'll get married," answered Roger. They had been looking for a house for two years. Finally Ruth grew dead tired. In a week he got a letter. "I don't think you really love me. So I have found a man who will take good care of me and I'll be married to him today. Ruth." Soon she got a letter from Roger, "I am very unhappy, but the most important thing for me is your happiness. I am sending you several addresses and I am sure that you'll find among them a decent house. Roger."​
