Answer:
challenges of the present and the future
Explanation:
It is important that we study the past so that it is possible to achieve a better future and to be able to understand and pass through the present in a satisfactory way. This is because the past is able to show us the mistakes and successes of our society, showing us what created the challenges we face in the present and guiding us on the way to overcome these challenges, now and in the future, because we know that the challenges of future will be the result of what we learn in the present with the study of the past.
