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.

Ex Input:
Sentence: I couldn't put the pot on the shelf because it was too tall.
 Question: Why does the 'it' refer to the pot?

Ex Output:
Because Most likely the pot couldn't fit on the shelf because it was to tall for the shelf space, however it could also be that the shelf was to high to reach to put the pot on.  But tall most likely refers to the pot rather than the shelf.


Ex Input:
Sentence: Many people start to read Paul's books and can't put them down. They are popular because Paul writes so well.
 Question: Why does the 'They' refer to paul's books?

Ex Output:
Because People love Paul's books. They are popular. So the books are popular, not the people.


Ex Input:
Sentence: Tom threw his schoolbag down to Ray after he reached the bottom of the stairs.
 Question: Why does the 'he' refer to ray?

Ex Output:

Because Tom threw his bag down, meaning he was at the top. Ray had to be at the bottom.
