Letter Choice	Evaluation	Justification
A	Likely	There is excellent correlation of the Erosion Resistance Index with elevation. High areas are underlain by resistant materials; low areas by less resistant.
B	Likely	The landform is underlain by loose material consistent with that deposited by landslides.
C	Likely	The land surface is parallel to the layers.
D	Likely	The land surface is not parallel to the underlying layers.
E	Likely	Low areas are underlain by resistant material; high areas by less resistant material.
F	Likely	The landform is underlain by loose material consistent with that deposited by ice.
G	Likely	The landform is underlain by well-sorted layers of loose material.
H	Unlikely	The landforms are underlain by bedrock, not loose material.
I	Unlikely	There is no correlation between the Erosion-Resistance Index and elevation.
J	Unlikely	There is good correlation between the Erosion-Resistance Index and elevation.
K	Unlikely	The landform is underlain by loose material, not bedrock.
L	Unlikely	There is no parallelism between the land surface and the layers.
M	Unlikely	The landform is underlain by material consistent with that deposited by ice.
N	No Evidence	The higher areas are covered by loose material; the lower areas are underlain by bedrock.
O	No Evidence	Because there are no layers, parallelism between the land surface and the underlying layers cannot be tested.
P	No Evidence	The land surface is not quite parallel to underlying layers.
