Which statement best describes a historian? A historian primarily finds out the truth about events from the past. A historian tries to explain present-day events based on the past. A historian works to discover why a contemporary event occurred. A historian mostly corrects mistakes of investigators from long ago.

I think its A historian primarily finds out the truth about events from the past.

Today there are five such libraries left in Chinguetti containing some 1,300 Quranic manuscripts. The crumbling texts are gingerly handled by scholars who still occasionally visit the site to debate Islamic Law. Unfortunately Chinguetti is suffering from the aggressive expansion of the Saharan desert surrounding it and these historically significant texts are in great danger of being destroyed by the dry air and shifting sands. Preservationists have attempted to relocate the collections or set up restoration programs locally, but the private owners of the libraries refuse to let the texts leave the succession of being passed down and traded amongst themselves.

UNSECO has marked the city of Chinguetti and other ancient settlements nearby as World Heritage sites, and efforts are being made to save the city and its libraries from desertification. Unfortunately local political turmoil has made it hard to focus on such projects. With luck Chinguetti will not finally succumb to the sands of time.
