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.

Example Input: Sentence: The man couldn't lift his son because he was so weak.
 Question: Why does the 'he' refer to the man?
Example Output: Because The man couldn't lift, why? Because he was weak.

Example Input: Sentence: Jackson was greatly influenced by Arnold, though he lived two centuries earlier.
 Question: Why does the 'he' refer to arnold?
Example Output: Because "Was" is past tense. He was influenced by Arnold. So you assume Arnold is dead.

Example Input: Sentence: George got free tickets to the play, but he gave them to Eric, because he was not particularly eager to see it.
 Question: Why does the 'he' refer to george?
Example Output:
Because George gave them away.
