Explanation:

- Sentence A: Absulum, the reindeer elf worked in the reindeer barn.

This sets the scene and introduces us to Absulum's job and location.

- Sentence B: He also had to keep the reindeer well-groomed.

This logically follows tasks related to the job's requirements.

- Sentence C: He had to clean it every day and that was hard work.

Cleaning every day emphasizes the challenging aspect of Absulum's duties.

- Sentence D: He had to give them all a bath and brush their fur.

This is another specific task related to grooming and care of the reindeer.

- Sentence E: It was such a dirty job to mop, slop, scour and scrape every corner.

It describes the nature of the cleaning tasks in more detail.

- Sentence F: He worked his fingers to the bone but it seemed that no one cared.

This concludes with a reflection on his hard work and lack of recognition.

- Analyzing the logical flow:

- The sequence should start with cleaning details (C) before detailing reindeer grooming (D, B), and finally, a more nuanced look at the cleaning task (E).

- Correct Answer: 3
