Respuesta :
The sentence
which uses a comma splice is the first one, “Two great
ballet dancers began their careers in St. Petersburg, they were Anna Pavlova
and Vaslav Nijinsky”. There are two independent clauses which can stand alone
joined by a comma. All the other sentences are composed of phrases.
The correct answer is:
Two great ballet dancers began their careers in St. Petersburg, they were Anna Pavlova and Vaslav Nijinsky.
