Choose the option that best complete the gap (s): It was very easy for the two political parties from a_______Government.

The option that best completes the gap is "coalition." A coalition government is formed when two or more political parties come together to form a majority in a governing body. This is often done when no single party has been able to win a majority in an election on their own. In this context, it would make sense that it was "very easy" for the two political parties to form a coalition government, as they were able to work together to form a majority. "Collusion" refers to a secret agreement between two or more parties, usually for an illegal or dishonest purpose. This would not be an appropriate word to use in the given sentence. "Co-operative" refers to people or organizations working together for a common purpose. While a coalition government could be described as a type of co-operative effort, it is not the most fitting word choice for the sentence. "Colonial" refers to something related to a colony or colonies, which is not relevant to the given sentence.
