It contains one dependent and one independent clause.
Answer: Option 3.
<u>Explanation:</u>
A dependent clause is also known as the subordinate clause. It is that which is a part of the sentence which adds extra information to the particular sentence of which it is a part. But it is nothing without a sentence. It can not stand without it.
On the other hand, independent clause is a clause which has a meaning itself also. In other words, it stands as an independent sentence in itself and does not need to be a part of some other sentence necessarily to make a meaning out of it.
It really depends on the movie. For instance, in Apollo 13, scenes were shoot aboard a Boeing KC-135 or the Vomit Comet. It is a NASA's refueling tanker plane for Zero G training. Astronauts wanna-be would fly up in the plane and experience a free fall.
