Uplift of the Colorado Plateau was a key step in the eventual formation of Grand Canyon.
Step-by-step explanation:
 
        
             
        
        
        
12, 13, 15, 20, 24, 25, 26, 31, 33, 34
First, let's just find everything (minimum, maximum, Q₁, median {Q₂}, Q₃)
Minimum : 12, because it is the lowest number.
Maximum : 34, because it is the highest number.
Median (Q₂) : 24.5, because it is the middle number.
Q₁ : 15, because it is between 24.5 and 34
Q₃ : 31
So, 
1)  d-12
2)  c - 34
3)  b-15
4)  f-24.5
5)  a-31
