Question

Which contains an independent clause?

Because the tragic fumble was scored by the visiting team in the last minute.
When the player, in an extraordinary move, went charging down the field.
As the uproar from the delirious fans exploded jubilantly through the stadium.
While the team made their play, the frenzied crowd cheered them to victory.

Answer 1

"While the team made their play, the frenzied crowd cheered them to victory."

Explanation: the second half ("the frenzied crowd cheered them to victory") is an independent clause (it can stand alone). The other three begin with subordinating conjunctions (Because, When, As) and are dependent.
