The answer to your question is c.invented because it's a past participle.
Novels are long, usually with multiple chapters. They verify to 50 words to 60 pages but a short story is way shorter then a novel.
Answer:
A) The correct answer is C) the mistake helpfully reveals the way Azy's mind works.
B) The correct option is D) "Maybe this can teach us a little bit about how he thinks."
Explanation:
A) Azy - an Orangutan in captivity which is being used for experiments in the behaviour of primates, especially learning, is presented with a bag containing food.
Azy is given options on a screen to select from, and instead of picking food, he picks another symbol which represents a container.
According to the researchers, the right answer would have been the symbol which connotes food. However, Shumaker is elated to note that the Orangutans have the ability to put things into categories.
B) In the last paragraph of the excerpt, Shumaker states that in his opinion, the mistake shows that Azy in his mind is learning or can put objects into categories and that that by itself could be a pointer to how Orangutans think.
Cheers
