Questions & Answers about Vilket krav förstår kandidaten inte?
Why do we use vilket instead of vilken here?
Because the word krav (requirement) is an ett word (ett krav). When asking 'which' about an ett word, you must use vilket. If it were an en word, you would use vilken.
Why is the verb förstår placed before the subject kandidaten?
This is the Swedish V2 rule in action! The entire question phrase Vilket krav takes up the first position in the sentence. The verb förstår must come second, which forces the subject kandidaten to move to the third position.
Why does inte go at the very end of this sentence?
In a regular Swedish main clause, inte comes after the verb and the subject. Since the verb förstår and the subject kandidaten are pushed slightly later by the question phrase at the start, inte naturally falls at the very end.
The English translation uses 'does ... understand', but the Swedish sentence only has förstår. Why?
Swedish doesn't use helper words like 'do' or 'does' to make questions or negatives. You simply use the main verb förstår (understands) and let the word order show that it is a question.
