Which statement about the geography of japan is most accurate?
location has made it easy to invade.
the irregular coastline has many natural harbors.
large plains are its primary physical feature.
earthquakes do not threaten the islands.

where are the choices

i believe the answer is: true

our brain need to reach a certain level of development   before it could interpret and understood sound with high difficulties. to proof this, we just need to pay attention in musical preference between children and adults. it is far less likely that children would enjoy things such as orchestra or rock band as much as adults due to the difference in this ability.
