Question

which is the best way to complete the text? olivia was an experienced speed chess ________ still struggled with the pace of competitive tournaments. player but player, but player; but

Explanation:

A comma is used to separate an independent clause from a contrasting independent clause when using the conjunction "but". "Olivia was an experienced speed - chess player" is an independent clause, and "still struggled with the pace of competitive tournaments" is an independent clause. A semicolon is not needed before "but" here as it's not joining two independent clauses that are more closely related in a list - like or complex way.

Answer:

player, but
