Question: In the early morning of 10 April, leading elements of the Austrian army crossed the Inn River and invaded Bavaria. The early Austrian attack surprised the French; Napoleon himself was still in Paris when he heard about the invasion. He arrived at Donauworth on the 17th to find the Grande Armee in a dangerous position, with its two wings separated by 75 miles (121 km) and joined together by a thin cordon of Bavarian troops. Charles pressed the left wing of the French army and hurled his men towards the III Corps of Marshal Davout. In response, Napoleon came up with a plan to cut off the Austrians in the celebrated Landshut Maneuver. He realigned the axis of his army and marched his soldiers towards the town of Eckmuhl. The French scored a convincing win in the resulting Battle of Eckmuhl, forcing Charles to withdraw his forces over the Danube and into Bohemia. On 13 May, Vienna fell for the second time in four years, although the war continued since most of the Austrian army had survived the initial engagements in Southern Germany.

Answer: On what date did the Austrian army first cross the Inn River?

Question: Similarly, forensic anthropologists draw on highly heritable morphological features of human remains (e.g. cranial measurements) to aid in the identification of the body, including in terms of race. In a 1992 article, anthropologist Norman Sauer noted that anthropologists had generally abandoned the concept of race as a valid representation of human biological diversity, except for forensic anthropologists. He asked, "If races don't exist, why are forensic anthropologists so good at identifying them?" He concluded:
