Understanding the Correct Option
The sentence in question is: "He was tired ______ he kept running." The correct answer is option 'B' (but). Here's why:
Contrasting Ideas
- The conjunction 'but' is used to connect two contrasting ideas in a sentence.
- In this case, "He was tired" and "he kept running" present opposing situations: being tired usually implies a desire to stop, while running indicates continued effort.
Role of 'but'
- Using 'but' highlights the unexpectedness of the situation.
- The listener or reader understands that despite feeling tired, the subject chose to continue running, which is a surprising or noteworthy action.
Analysis of Other Options
- Option A: sob
- This is not a conjunction and does not fit the sentence structure.
- Option C: and
- 'And' would imply that both conditions are true without any contrast. It would suggest that he kept running because he was tired, which is not logical.
- Option D: yet
- While 'yet' can signify contrast, it is typically used to indicate something that happens unexpectedly or after a long time, which doesn’t fit as well here as 'but'.
Conclusion
- Therefore, the most appropriate conjunction for this sentence is 'but', as it effectively conveys the surprising action of continuing to run despite being tired.
