These lines, so typical of Austen’s wry tone, allow Austen to “criticize social conversation as pointless and insincere” and “reveal Lady Middleton's character as superficial and proud”. This passage shows how social conversations are not necessary as they don't provide relevant information and people just uses them to talk about insignificant details and to avoid uncomfortable silence. The author also describes the personality of Lady Middleton as being superficial and how she uses her son to start an irrelevant talk.
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.
