Teacher: In this task, you're given an input that contains two words, and your task is to predict the correct preposition that connects these two words. Predict the preposition that explicitly conveys both words' meaning, e.g., Word1: king 
 Word2: fort: "king of fort". Possible prepositions are: "of", "on", "in", "for", "from", "about", and "with".
Teacher: Now, understand the problem? If you are still confused, see the following example:
Word1: story 
 Word2: pearl
Solution: of
Reason: The preposition correctly connects two words turning it into the sentence 'story of pearl'.

Now, solve this instance: Word1: head 
 Word2: company
Student:
of
