Did your alien have more or less features in common with your peers? Why do you think so?

the answer is otpion c) understanding

he wants to be heard one more time. he wants to be understood. he needs the truth one more time.

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.
