Hello, The value would return 'true' in this case because as you mentioned Sara learnedJava and learnedPython (took the tracks). This is so because the statement is asking if Sara learned java OR ( || ) python OR ruby, so if any of those are true the result will be true. If Sara had only learned java, it would return true as well because you only need one statement to be true. OR (||) means only one item needs to be true for the statement to be true. AND (&&) means all items need to be true in order for the statement to be true.

Hope that helped!
