Accepted Answer

Tower density decreased while the point pattern stayed essentially the same.

Answer

Tower density increased while the point pattern stayed the same.

Answer

Tower concentration increased because the city became larger.

Answer

Tower density stayed the same because the tower count stayed the same.

Question 16

Answer

Density decreased while concentration stayed equal.

Answer

Density increased while concentration decreased.

Answer

Answer

Clinic density falls, and concentration in the medical district rises.

Answer

Clinic density stays the same, but concentration rises.

Answer

Clinic density rises, but concentration must fall.

Question 18
