Answer: 2
SPARQL: SELECT (COUNT(DISTINCT ?e) AS ?count) WHERE { ?e <pred:instance_of> ?c . ?c <pred:name> "river" . ?e <watershed_area> ?pv . ?pv <pred:unit> "square kilometre" . ?pv <pred:value> ?v . FILTER ( ?v > "2700000"^^xsd:double ) . ?e <discharge> ?pv_1 . ?pv_1 <pred:unit> "cubic metre per second" . ?pv_1 <pred:value> ?v_1 . FILTER ( ?v_1 != "2400"^^xsd:double ) .  }
