TASK DEFINITION: In this task you need to give reasons to justify the pronoun coreference relations. Each of the provided inputs contains a sentence with a target pronoun and a question about how to justify the coreference between a noun phrase and the target pronoun. Good practices involve the discussion about how the descriptions attached to the targeted pronoun relate to the noun phrase candidate in the question. The reasoning could come from one or multiple following knowledge types about commonsense: First: 'Property', the knowledge about property of objects (e.g., ice is cold). Second: 'Object', the knowledge about objects (e.g., cats have ears). Third: 'Eventuality', the knowledge about eventuality (e.g., 'wake up' happens before 'open eyes'). Forth: 'Spatial', the knowledge about spatial position (e.g., object at the back can be blocked). Fifth: 'Quantity', the knowledge about numbers (e.g., 2 is smaller than 10). Sixth: all other knowledge if above ones are not suitable. Write the sentence in natural language.
PROBLEM: Sentence: It was a summer afternoon, and the dog was sitting in the middle of the lawn. After a while, it got up and moved to a spot under the tree,  because it was cooler.
 Question: Why does the 'it' refer to the spot under the tree?

SOLUTION: Because animals feel hot move to cooler places.

PROBLEM: Sentence: My meeting started at 4:00 and I needed to catch the train at 4:30,  so there wasn't much time. Luckily, it was delayed, so it worked out.
 Question: Why does the 'it' refer to the train?

SOLUTION: Because the code word is been used to make it in a change so it is been done in a public spot to decrease attention.

PROBLEM: Sentence: Bob paid for Charlie's college education, but now Charlie acts as though it never happened. He is very ungrateful.
 Question: Why does the 'He' refer to charlie?
