The first one. 
Explanation:
In this first one, the author is pulling apart what the evidence means (analysing it). 
In the 2nd, it is NOT analyzing a piece of evidence specifically, it's summarizes the point and says it's supported by the evidence. So, not analyzing.
In the 3rd, the author is applying it to the situation and explaining why it's important, which is different from analysis.
In the 4th, the author is offering an example as evidence, not analyzing a piece of evidence. 
 
        
             
        
        
        
Answer:
A shallow
Explanation:
Something that is described as shallow is "of little depth". The initial description given of the canal is that of a body of water that  was not deep enough to allow the passage of large ships. To solve this problem of the canal being shallow, dredgers had to be used to reach the bottom of the canal, thus increasing the depth of the canal. 
After this was done, an improvement was seen in the increased number of ships plying the canal water body.

The conflict is based on the wrongs committed by one man to another.
