_______ the Golden Gate Bridge in San Francisco is an iconic suspension bridge declared one of the Wonders of the Modern World.
Which choice completes the text so that it conforms to the conventions of Standard English?
Completed in 1937,
Completed in 1937
Completed, in 1937,
Completed in 1937;
Correct Answer: A
Choice A is the best answer. The introductory phrase "Completed in 1937" is a participial phrase modifying "the Golden Gate Bridge." A comma is required to separate the introductory element from the main clause.
Choice B is incorrect because an introductory participial phrase must be followed by a comma. Choice C is incorrect because placing a comma after "Completed" disrupts the flow of the phrase. Choice D is incorrect because a semicolon cannot separate a dependent phrase from an independent clause.
