Teacher:You are given a conversation between two people. 'Person1:' and 'Person2:' are used to separate their respective dialogues. You are required to assign a label 'formal' if there is an absence of emotion and a presence of questions anywhere within the conversation. If such pattern is not found assign the label 'informal'.
Teacher: Now, understand the problem? Solve this instance: Person1: Do you like climbing ?
Person2:Yes , I like it very much .
Person1: How about climbing up the Fragrant Mountain tomorrow ?
Person2:Where is it ?
Person1: It is located at the east foot of Western Mountain of Beijing , in a park with the same name . There are some huge stones within the mountain which look like the censer , so it is called ' Fragrant Mountain ' .
Person2:Have you visited it before ?
Person1: Many times . Except climbing , there are many attractions worth visiting .
Person2:Like what ?
Person1: It is the best season to view red leaves from the Mid-October to the first ten days of November . During the period , thousands of hectares of maples on the sloping field are so red that you would recognize them as fallen petals by mistake if looking from a further area . The bright red , pink , scarlet , and peach-puff leaves are distributed in different layout , with some green pines and cypresses dotted in between .
Person2:Sounds marvelous .
Person1: You can take a bird-eye view at the glorious picture when you arrive at the top of the mountain .
Person2:Great . I will prepare some clothes and food for the climbing .
