Answer 1

Send a CONSTRUCT query. A little example:

CONSTRUCT { ?s ?p ?o }
WHERE { ?s ?p ?o }
LIMIT 10

The WHERE clause works just like that of SELECT only the values fill the CONSTRUCT block as a kind of template. It's very flexible - you can either copy statements as here or transform them into a completely different shape.
