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.

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?
Because George gave them away.

Sentence: John couldn't see the stage with Billy in front of him because he is so short.
 Question: Why does the 'he' refer to john?
Because John had a taller obstacle.

Sentence: Fred is the only man alive who still remembers my father as an infant. When Fred first saw my father, he was twelve months old.
 Question: Why does the 'he' refer to my father?

Because Fred wouldn't remember something that happened when he was twelve months old.
