Help I’m having some trouble understanding this “You are standing at the corner of River Street and Third Street. A friend calls and tells you to walk three blocks west of your present position to meet her. Where is your friend? What is the reference point for her directions”

is this a psat question, if so do not cheat try your best.

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.

if you look up in the top right corner you'll see your current profile picture, click than click "view profile" you'll be able to change it there.
