Read the rule first. Then read the questions from the dialogue between Max and the guest. Which endings do the question words take?
The ending of "welch -" follows the declension of the definite article.
In the nominative, the masculine singular receives the ending "-er", the neuter singular the ending "-es", and the feminine singular the ending "-e".
The plural ending is always "-e".
In the accusative masculine singular, the ending is "-en". For feminine and neuter nouns, there is no difference between the nominative and accusative.
