Answer: The conjunction is "but" and it is a coordinating conjunction
Step-by-step explanation:
Conjunctions are words that link different elements in a sentence including clauses. In the case of the sentence presented the conjunction is "but" because this is the element that links the clauses "The game began" and "the rain stopped it". Besides this, conjunctions can be classified as coordinating or subordinating conjunctions. The first ones link elements of the same importance and include the conjunctions and, so, but, if. The second type, link a dependent and independent clause such as the words because, if or although. This means in the conjunction "but" is a coordination conjunction.
