Brendan wrote the following sentence to explain how the game of checkers was solved:
In 1989, a group of computer scientists created a computer program called Chinook consequently; the program's algorithm finally became unbeatable in 2007.
What is the semicolon error in Brendan's sentence?
The second part of the sentence is not an independent clause and cannot stand alone.
The semicolon should appear before the conjunctive adverb consequently and the conjunctive adverb should be followed by a comma.
The sentence should include multiple semicolons to separate items in a serial list.
The word after the semicolon should be capitalized because it is a proper noun.
