Having trouble with question 3

My code is

SELECT name FROM fruit UNION ALL SELECT name FROM vegetable ORDER BY name DESC;

prompt is There are two tables Fruit and Vegetable table. The Fruit table has a FruitID and a Name column and the Vegetable table has a VegetableID and Name column.

Create a list of fruits and vegetables that includes any potential duplicate values. Ensure that it is in alphabetical order so that the duplicates are next to each other!

Thanks in advance!

The instructions include "Ensure that it is in alphabetical order" so you wouldn't use DESC.

SELECT Name FROM Fruit UNION ALL SELECT Name FROM Vegetable ORDER BY Name ASC;

SELECT Name FROM Fruit INTERSECT SELECT Name FROM Vegetable ORDER BY Name ASC; (Avocado, Bell Pepper, Cucumber, Eggplant, Olive, Plantain, Tomato, Zucchini)
