Final answer:
The sentence completion task involves determining the correct past tense verb to indicate that Mr. Budiman taught Indonesian at some point in the week, despite being absent on Monday. The correct verb is 'taught,' which fits the context of the sentence.
Step-by-step explanation:
The question seems to be a fill-in-the-blank exercise that aims to test the student's understanding of English verb tenses and sentence structure. Mr. Budiman, who teaches Indonesian language, was not present on Monday, but the sentence suggests that he still taught the language once during the week. The appropriate verb to complete the sentence would likely be in the past tense, to indicate that the event (teaching Indonesian language) occurred at least once at some other point during the week.
In order to fill in the blank and complete the sentence correctly, one could say 'Mr. Budiman...taught Indonesian language once this week.' This indicates that despite his absence on Monday, he conducted his teaching duties at least on one other day.
The final answer in a two-line explanation in 300 words is not needed as it wouldn't be possible to provide such a lengthy explanation for this simple sentence completion task. However, the concise final answer is: Mr. Budiman was absent on Monday, but this means that he taught Indonesian language once this week.
