Can't get question 2 for set questions.

why does the below not work?

select name from fruit where name > "L" union select name from vegetable where name > "L";

Any tips?

Having > "L" includes name from L to Z. You want < "L" for names A to K.

thanks for the help! It worked!

But I must admit I don't get why. Doesn;t it make sense that "name > "L" " represents letters greater than L? How does the logic work?
