Answer:
A. The results of the experiment showed a quantifiable decrease in oxygen levels.
Explanation:
The chosen sentence possesses a formal register with technical vocabulary related to science, which can be understood by professional scientists. For instance, the words <em>quantifiable </em>and <em>decrease </em>have a more academic style. Besides, the writing is impersonal and written in the third person.
The rest of the options are incorrect because they have contractions and they are too informal. Thus, their vocabulary contain casual expressions which do not follow the conventions of an academic style.
Autobiography is the word you're looking for.
Answer:
Creon's discovery that Antigone has hanged herself in her jail cell.
Explanation:
The following is the definition of falling action:
"Falling action occurs right after the climax, when the main problem of the story resolves. It is one of the elements of the plot of the story, the other elements being exposition, rising action, climax, and resolution. Falling action wraps up the narrative, resolves its loose ends, and leads toward the closure."
In this situation, I would be confident in saying that the climax was Antigone hanging herself - the discovery of Antigone in her cell dead would be her falling action, occurring right after the climax, leading towards closure.
