When researching a problem, why would it be worthwhile to examine past solutions? to ensure that new solutions are unique to identify every potential failure that may occur to prove that past solutions are the best solutions to see how the problem has been approached before

Hello there!

The statement below the question is true. When looking at a problem, researching or finding out past failures and solutions is worthwhile because of the fact that it would give you a view on some other way someone may have solved the same problem. It helps give you more insight.

Hope this helps!

D.)  to see how the problem has been approached before

Explanation:

When researching a problem, the priority is to find a solution and is important for it to be the best possible solution to avoid issues that could arrive in the future. The researcher needs to analyze all pros, cons and the implications of each possible solution. In order to understand the implications of the problem it is really helpful to know if the issue has been tackled before, and if so, what were the implications and consequences of the methods used. So it is important to look at the past, but only as a guide, and is necessary to review past information carefully and critically, to come up with the best possible solution for the current situation.
