The league of nations was less than effective for all of the following reasons except (1 point)
a. the united states did not join.
b. the united states did not ratify the treaty of versailles.
c. league members could not agree to use force against aggression.
d. president wilson did not support the idea.

I'd have to say C, the US and the Soviet Union couldn't agree on anything. The US favors capitalism while the Soviets favor Communism. All the major allied powers have a veto power, and the US and the USSR were total opposites, later however, the USSR is no longer an allied power.

Explanation:

land tenure is the legal regime in which land is owned by an individual, who is said to "hold" the land. It determines who can use land, for how long and under what conditions. Tenure may be based both on official laws and policies, and on informal customs. In other words, land tenure system implies a system according to which land is held by an individual or the actual tiller of the land. It determines the owners rights and responsibilities in connection with their holding. The French verb "tenir" means "to hold" and "tenant" is the present participle of "tenir". The sovereign monarch, known as The Crown, held land in its own right. All private owners are either its tenants or sub-tenants. Tenure signifies the relationship between tenant and lord, not the relationship between tenant and land. Over history, many different forms of land ownership, i.e., ways of owning land, have been established.

A landholder/landowner is a holder of the estate in land with considerable rights of ownership or, simply put, an owner of land.
