<span>the application of techniques like mass production
Let's look at the available options and see what makes sense.
the use of heat and open fires for cooking
- This sounds like the discovery of fire and as such it happened a long time before the nineteenth century. Wrong answer.
the application of techniques like mass production
- This one looks promising. We'll take if the other 3 options are just plain silly.
the introduction of earthenware such as clay vessels
- This is more recent than the discovery of fire. But it's still a long time ago. Literally thousands of years BC. So wrong answer.
the discovery of the technique of roasting raw foods
- Another discovery that happened thousands of years ago. So also the wrong answer.
So of the 4 choices, 3 of them happened literally thousands of years ago and so well before the nineteenth century. That leaves only 1 viable choices, so the answer is "the application of techniques like mass production"</span>
Once upon a time there was a pink duck who ate bread.
The end.
Their emphasis on the power of personal imagination puts them in the tradition of Romanticism, but unlike their forebears, they believed that revelations could be found on the street and in everyday life. The Surrealist impulse to tap the unconscious mind, and their interests in myth and primitivism, went on to shape many later movements, and the style remains influential to this today.
Just left to my own devices, I would have picked Stretch and/or Squash. The next closest thing (out of those three) is exaggeration. When you read the description of exaggeration, you find that physical characteristics can be exaggerated, but they should resemble some form of reality.
The second one is really a very close call. You could make a case for either secondary action, or follow through. The only one you could eliminate is pose to pose. That is reserved for how the action goes from one pose to another. That is more of a problem in technique than overall plotting. I think I'd pick follow through, because the character has stopped bouncing the ball, but he likely hasn't stopped sweating nor looking at his watch.
Pretty interesting question. You are not going to get asked that every day.
