Answer:
1 ) buprenorphine treatment
2) Convenience goods and services
3) furniture
4) electrical goods
5) hairdressing,
respectively
Explanation:
Threshold is the minimum population and range is the maximum distance needed to sustain a good. As such, it'd make sense for buprenorphine treatments (a rare service) to have a low threshold since not too many people will be buying it, but it's still sustainable since it's expensive.
"Medium" is a loose definition so I would say any convenience good or service would be good for this one.
Furniture would have a large threshold because a lot of people are moving and in need of furniture.
People are willing to travel great distances to get electrical goods because they're specialized goods and you can't just find them anywhere, thus, it has a large range.
Things like hairdressing aren't worth traveling great distances to receive so they have a small range.
Alluvial fan could be the answer. Alluvial fans are cone shaped deposits of sedimentary particles. The particles can be sand. silt, gravel or clay. These land-forms are formed at the mouth of canyons or in valleys where ephemeral streams can occasionally transport material to the mouth of the canyons. An ephemeral stream is one that is created after a shower of rain or other form of precipitation; they are not permanent streams. <span />
