Fill in the blank with the most appropriate conjunction:
He will be promoted ____ he improves his communication and leadership skills.
Show answer & explanation
Correct answer: C
Explanation
The conjunction 'provided that' (or simply 'provided') is used to introduce a condition that must be met for something else to happen. In this sentence, the promotion is conditional upon the improvement of skills.
'Unless' means 'if not', which would change the meaning to the opposite.
'Although' introduces a contrast, which is not suitable here.
'Whereas' is used for comparing two facts or situations, which is also not suitable in this context.
