The answer is ‘flex the wrist’. The ulnar nerve is a major peripheral nerve of the upper limb. It runs near the ulna bone hence its name. This is the nerve that causes an electric shock-like sensation when the medial epicondyle of the humerus is struck posteriorly, or inferiorly with the elbow flexed.

i am positive it is c. condensing but i may be wrong

sheep is a herbivore animal whereas grasshopper belongs to the class chordates but both of them feed on greens.  

if grasshopper and sheep feeding on a pasture land, i do not think both of them will have any impact on each other. however, the number of the species can make difference. since sheep feed on greens, there is a possibility there left no pasture land for the grasshoppers or they may get extinct.
