Given a paragraph about movies, and a set of conversational question answers about the paragraph, answer a follow-up question from the paragraph. The paragraph has the prefix 'CONTEXT:'. Each conversation question has a prefix `Q:` followed by the answer prefix `A:`, and the follow-up question has a prefix `FOLLOWUP_Q:`.

Let me give you an example: CONTEXT: The balance of power had shifted considerably since the first set of quotes. King Joffrey is dead, and his younger brother Tommen is now king. Unlike his wild card of an elder brother, Tommen is gentler and more prone to manipulation by his new bride. The Lannisters impeccable image has also been shattered. They failed to prevent the assassination of their king in the midst of his own wedding day, and the suspected assassin is the king's Lannister uncle. Not only do they look incompetent, they are divided among themselves. On the other hand, the Tyrells' situation is much stronger now. Tommen is already wrapped around Margaery's pretty little finger, and she knows that the assassination was orchestrated in part by her own family. In Margaery's eyes, the Lannisters look disoriented and lost. Putting on a show trial for one of their own, whom she knows is innocent of any wrongdoing. Whatever power Cersei held over Margaery has now been diminished. <sep>  Q: What was Margaery's motivation to call Cersei 'sister' again? A: Whatever power Cersei held over Margaery has now been diminished. <sep> FOLLOWUP_Q: Why has it been diminished?
The answer to this example can be: King Joffrey is dead, and his younger brother Tommen is now king.
Here is why: The answer why Cersei's power over Margaery has now diminished is clearly mentioned in the passage.

OK. solve this:
CONTEXT: Of course this changes from country to country, but generally speaking it's not illegal to film on the streets, since it's a public area. Most car scenes are recorded with chroma just for pratical reasons. In a professional production you look for "quality" and you can achieve it only if you have control. It's all about control. With a studio setting you get full control of the lights, the movements, etc. in one word, the scene. And of course, you minimize the hitches that can occurs in the real world (also safety concers). However you should film outdoor shots to enrich and give credibility to your scene.  <sep>  Q: Why are most scenes in a car recorded with chroma?
