CHANGES TO TASK DESCRIPTION

...

* Example of SPARQL query that lists QAs for a particular case of (1) where QB = Q12280 (bridge): [[ https://query.wikidata.org/#SELECT%20DISTINCT%20%3FQA%20%3FQALabel%20WHERE%20%7B%0A%20%20%3FQA%20wdt%3AP31%20wd%3AQ12280.%0A%20%20%3FQA%20wdt%3AP31%20%3FQC.%0A%20%20%3FQC%20wdt%3AP279%2a%20wd%3AQ12280.%0A%20%20FILTER%20%28%3FQC%20%21%3D%20wd%3AQ12280%29.%0A%20%20SERVICE%20wikibase%3Alabel%20%7B%20bd%3AserviceParam%20wikibase%3Alanguage%20%22en%2Ces%22.%20%7D%0A%7D | The Query ]]
