You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues.

[EX Q]: Person1: I ' m thinking about redecorating my bedroom . I bought this magazine in order to get some ideas . What do you think of this ?
Person2:That looks good . The room in the picture is bigger than your bedroom , so you wouldn ' t be able to have all that furniture in your room .
Person1: I ' d like to have the bed and the wardrobe .
Person2:You would fit both of them in your bedroom . Perhaps you could also get the dressing table . I think that one would look good in your bedroom .
Person1: Yes , it would . It ' s very expensive though .
Person2:Everything in this magazine seems expensive . You could probably find something similar in a discount store .
Person1: Yes . I ' m sure I could find something similar at one . I ' d also like to get a new carpet for my bedroom .
Person2:You can get cheap carpets easily . Another idea is to buy a rug . That would cover a lot of the carpet and you wouldn ' t have to replace the carpet . It would save you a lot of work .
Person1: That ' s a good idea . I ' m really looking forward to redoing my bedroom .

[EX Q]: Person1: Would you like to go skiing with me ? I heard the new ski area is great . They have safe tracks , especially for the beginners and provide free training . I think it suits you best .
Person2:Sounds not bad ! You know , the only thing I worried about is the safety . I ' m not an active exerciser and my muscle may be not strong enough for such an intense sport .
Person1: Then you can go to the three-day-long training camp first . There ' re some professional teachers and they can guide you to do certain necessary exercise .
Person2:I will think about it .
Person1: Come on ! It is really a fun game .
