Maybe try allowing more versions of Baja. I used all three words, Baja, California, and peninsula in combinations of two-- Baja peninsula, Baja california, etc.
I think I forgot about the b part bc I was convinced it should be spit, taiga, and ecosphere lol (which as far as I can tell are all synonyms for their answers except spit which has to only be connected at one end)
Think it should say 'of freshwater in the world' to make it clearer
