20. The dictionary is ___. It only goes to the letter J. (COMPLETE)

The correct answer is incomplete.

Explanation: If a dictionary only goes up to the letter 'J', it means it does not contain all the letters of the alphabet. Therefore, it is not complete. 'Incomplete' signifies that something is missing or not finished.

Translation: Словарь неполный. Он содержит только буквы до J.
