-Predictions based on big data. For an example big data could make it possible to detect possible criminals even before they commit crimes. However it is worth to notice that big data predictions are based in correlation and in direct evidence. No prediction is ever completely accurate. Also basic human rights protect individuals from prosecution before they have done anything from. These kind of predictive methods should be utilized extremely carefully and actions based on these predictions should be only guiding.  +Predictions based on big data.

 +
 +A really important question without perfect answer. Books provide solutions. Checks if student has read the books. Because answers are spread throughout the pages. Also requires creative thinking. Combined since the concepts overlap. 
 +
 +**4.**  Give an example of a scenario where open data could be used for profit.  Also describe how profit would be generated.
