Answer:
Documentary
Explanation:
<u>Documentary movies are non-fiction movies that document reality. They are usually used to</u> <u>inform</u> <u>the audience of something, to </u><u>educate </u><u>them</u>, <u>or </u><u>call to action</u>. Many documentary movies are socially engaged, which means they present some narrative about a certain problem, ways how to solve it, and people who are dealing with it.
The film idea posed in the question is <u>ecologically engaged</u>. It would include presenting the benefits of solar power, the harm of overuse of electricity, and ways how to switch to the former. <u>That is why the film trying to call for action and convince people of switching to solar power would be a documentary movie. </u>
What Frère Jacques has to do with Mahler's first symphony is that Frère Jacques' song was infused in the third movement of Gustav Mahler's first symphony.
Not only that, Gustav Mahler intended to change the symphony from minor key to major key as his first symphony was a funeral march.
Thus, Frere Jacques's song contains the major key, while the rest of the symphony has a minor key.
Gustav Mahler's first symphony has four-movement structures.
Hence, in this case, it is concluded that Frère Jacques' song was infused in the third movement of Gustav Mahler's first symphony.
