A large region has a low arithmetic density. Which conclusion is justified by that average?
- A
Residents must be spread evenly across the region.
- B
Residents may be concentrated in a few cities while much of the region is sparsely populated.
- C
The region must have little or no urban settlement.
- D
The region must have a small total population.

A region has high physiological density. Select all conclusions supported by that measure.
- A
It may indicate pressure on land suitable for crop production.
- B
It proves that the region has a food shortage.
- C
It compares the population with arable land.
- D
It establishes that crop yields are low.

One region has a higher agricultural density than another. Which interpretation is best supported?
- A
The measure may suggest labor-intensive farming, but does not establish that the region is more productive.
- B
The measure proves that the region produces more food per hectare.
- C
The measure counts every resident in the numerator.
- D
The measure shows the share of total land that is arable.

You are comparing density figures from two datasets. Select all checks that help make the comparison meaningful.
- A
Check that the regions use consistent boundaries.
- B
Use different years so the comparison includes more data.
- C
Check that the population numerator and its definition are comparable.
- D
Assume that every dataset counts the same population.

For a region, physiological density is four times its arithmetic density. Assuming both measures use the same population and boundaries, what does this imply about the region's arable land?
- A
Arable land is four times the region's total land area.
- B
Arable land is one-quarter of the region's total land area.
- C
The population is four times larger than the population used for arithmetic density.
- D
The region has four times as many farmers as residents.

A planner sees high arithmetic density across a region. Which concern is this measure most directly useful for flagging?
- A
It can signal broad pressure on housing, transport, infrastructure, and urban land.
- B
It proves that every locality in the region has the same level of crowding.
- C
It directly measures pressure on crop-suitable land.
- D
It identifies how many farmers work each unit of arable land.

Physiological density
- C
Agricultural density

For the same region and population, its physiological density is four times its arithmetic density. What does this imply about the amount of arable land compared with total land?
- A
Arable land is four times the total land area.
- B
Arable land is one-quarter of the total land area.
- C
Arable land equals the total land area.
- D
The region has four times as many farmers as people.

A region has high agricultural density. Which interpretation is best supported by that measure alone?
- A
It proves that the region produces more food per hectare.
- B
It measures the whole population relative to total land.
- C
It indicates many farmers per unit of arable land and may suggest labor-intensive farming.
- D
It proves that food is scarce.

- A
Physiological density rises, while arithmetic density stays the same.

Arithmetic density rises, while physiological density stays the same.
- C
Both densities stay the same.
- D
Both densities fall.
