Final answer:
The coordinating conjunction 'yet' connects the independent clauses in the sentence.
Step-by-step explanation:
The coordinating conjunction “yet” connects the independent clauses in the sentence:
The weather was cold and wet, yet we played outside for most of the afternoon.
When connecting two independent clauses, you can use coordinating conjunctions such as and, but, or, yet, so, among others. In this case, the word “yet” shows contrast between the cold weather and playing outside. Note that you should use a comma before the coordinating conjunction when connecting independent clauses.
