Final answer:
The word that best completes the sentence is 'contemptuous' which means showing contempt or lack of respect, similar to 'arrogant insolence,' the behavior that led to Anna being fired. Option 2 is correct answer.
Step-by-step explanation:
The question presented asks us to complete the sentence with the word that best fits the context of the sentence, specifically describing Anna's behavior that got her fired. Given that we are looking for a word that describes behavior that the company would not tolerate and that is in line with 'arrogant insolence', the correct answer is:
d) contemptuous
'Contemptuous' refers to showing contempt or a lack of respect, which is similar to 'arrogant insolence' and therefore fits the context of the sentence. The other options are:
- 'Assiduous' means showing great care and perseverance.
- 'Stolid humble' is not a commonly used phrase, but if we separate the words, 'stolid' means calm, dependable, and showing little emotion while 'humble' indicates a modest or low view of one's importance.
- 'Deferential' means showing deference; respectful.
Thus, the word contemptuous best matches the description of Anna's behavior that resulted in her termination, as it aligns with an attitude of arrogance and disrespect that the company found intolerable.
