Answer:
(B) The idea wasn't invented until 1935.
Explanation:
The best answer would be (B), since prior to that year, all movies were silent ones. Silent movies are movies without any sound, which started since the late 19th century until they early 20th century.
Though by 1927 movies were already released with sounds, such as the musical The Jazz Singer, none were composed specifically for each movie.
WIth Max Steiner's film score for King Kong, the trend starts, however. King Kong was released in 1933, and after the release more movies had their own film scores. 1935 was also the year when Academy Awards started giving awards for Best Original Film Score.
Filling the frame means that you focus solely on the subject and that subject occupies most if not all of the photograph. Doing this will place more emphasis on the subject to draw more attention to it.
For example, let's say you photographed someone standing on a hill. If you do a wide shot and photograph the person along with the hill and the sky above, then readers won't focus as much on the person. The person would likely be too far away. If you zoom in on the person, and have them fill more of the frame, then more focus will be placed on the subject.
While filling the frame is a useful technique, it doesn't mean that you always have to do it. Going back to the wide shot example, that could be useful if you want to have the person contrast with their surroundings. It's also a good visual way to show how vast nature is compared to humans. Famous landmarks such as the grand canyon could be a better backdrop to use. So it all depends on what you're trying to convey and what message you're trying to send.
