question about FROM keyword

[Zlatareva, Neli (Computer Science)]

Hi there, I am trying the following arq query from command window
(works fine if I am getting the file locally)

PREFIX ab: <http://learningsparql.com/ns/addressbook#>
SELECT ?last ?first ?courseName
FROM <http://www.learningsparql.com/2ndeditionexamples/ex069.ttl>
WHERE
{
  ?s ab:firstName ?first ;
     ab:lastName ?last ;
     ab:takingCourse ?course .
  ?course ab:courseTitle ?courseName .
}

I am getting the following error

D:\neli\cs575Spring24>arq --query ex070mod2.rq

Your help will be greatly appreciated. I just downloaded the latest version of 
Apache-Jena and I am trying to run and test in command window.
Thank you so much.
