Question

one of the first things the delegates decided on was a new structure for the central government. they planned a central government made up of three branches. why did the delegates want the new government to have three separate branches?
to make the central government as small as possible

to prevent any one group from having too much
power

to prevent the central government from claiming
land west of the mississippi river

to make the central government more efficient

Explanation:

The concept of separating the central government into three branches (like legislative, executive, judicial in the US context) is based on the principle of checks and balances. The goal is to prevent any single group or branch from accumulating excessive power. The other options are incorrect: making the government small isn't the purpose of three - branch structure, the three - branch system isn't related to land claims west of Mississippi, and while efficiency can be a by - product, the main reason for separation is power - balancing.

Answer:

B. to prevent any one group from having too much power
