Say Yes if it is answerable; otherwise, say No. 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:`.
Input: CONTEXT: The Transformers aren't very well explored in the Michael Bay movies, so we'll have to judge according to the other (better explored) continuities. While the process of switching alternate modes in the movie seemed effortless, it might not have been. In other continuities the switch is either energy consuming or a major physical operation. So just changing to another vehicle might be a very expensive step that one does not take lightly. Also, the alt-mode seems to be a very personal aspect for each Transformer, which serve a similar function as clothes do to humans. They are a reflection of the owner, and once it is chosen it tends to stay the same. Transformers have been known to keep the same alt mode for thousands of years, which isn't really that long when you remember that their life span can stretch into the millions of years.  <sep>  Q: Why do the Transformers always transform into the same cars?
