Question

Fill in the blank in the given sentence with one of the words that fits best : 
He disliked his job heartily, and therefore it was no surprise that he discharged his duties so _____.

Accepted Answer

Option 1, "perfunctorily," is the correct choice to fill in the blank in the sentence: "He disliked his job heartily, and therefore it was no surprise that he discharged his duties so _____."

1. **Explanation for Option 1: Perfunctorily**
   - The word "perfunctorily" means performing a task with minimal effort or reflection, often out of a sense of duty rather than interest or enthusiasm. In the context of the sentence, the subject dislikes his job, which suggests a lack of motivation or interest in performing his duties. Therefore, it is logical that he would carry out his responsibilities in a perfunctory manner, doing only what is necessary without any extra effort or engagement. This aligns perfectly with the sentiment expressed in the sentence.

2. **Explanation for why other options are incorrect:**

- **Option 2: Dogmatically**
     - "Dogmatically" refers to asserting opinions in an authoritative or arrogant manner, often without consideration for evidence or the opinions of others. This does not fit the context of the sentence, as it does not relate to the manner in which duties are performed when one dislikes their job. The sentence implies a lack of enthusiasm, not an authoritative assertion of opinions.

- **Option 3: Sardonically**
     - "Sardonically" means doing something in a mocking or cynical manner. While it might suggest a negative attitude, it does not accurately describe the way duties are performed when someone dislikes their job. The sentence focuses on the lack of effort or care, rather than a mocking or cynical approach.

- **Option 4: Wantonly**
     - "Wantonly" means doing something in a reckless or deliberate manner without regard for consequences. This does not fit the context of the sentence, as it implies a level of intentionality or recklessness that is not suggested by the dislike of the job. The sentence implies a lack of care or effort, not reckless behavior.

In conclusion, "perfunctorily" is the most appropriate word to fill in the blank, as it accurately reflects the lack of enthusiasm and minimal effort associated with performing duties when one dislikes their job.
