Answer:




And if we convert this into % we got 
See explanation below.
Explanation:
We assume that we have compounding interest.
For this case we can use the future value formula given by:

Where:
FV represent the future value desired = 1000000
PV= represent the present value = 50000
i = the interest rate that we desire to find in fraction
n = number of times that the interest rate is compounding in 1 year, since the rate is annual then n=1
t = represent the number of years= 50 years
So then we have everything in order to replace and we got:

Now we can solve for the interest rate i like this:



And if we convert this into % we got 
Answer:
the answer is natural;human
The correct answer to this is either generalizing or generalizabilty. Both mean the same and can be used interchangeably. It is basically an ability to generalize something based on a specific finding. It's not only on a broader group though, as it can also be done for its impact on natural environments based on a smaller finding.
