Question

which statement best represents an economic weakness of the national government under the articles of confederation?
states refused to collect taxes on behalf of the national government.
national and state taxes combined were too high for most citizens to pay.
congress set different tax rates for each state, leading to conflict.
the national government was unable to collect taxes.

Explanation:

Under the Articles of Confederation, the national government (Congress) had no power to tax directly. It could only request money from the states, and the states often refused or were inconsistent in providing funds. The option "The national government was unable to collect taxes" accurately reflects this key economic weakness. The other options are incorrect: states weren't refusing to collect on the national government's behalf (they were the ones with taxing power, and the national gov't couldn't tax), national taxes didn't exist (so combined taxes weren't an issue), and Congress didn't set state tax rates (states set their own, and Congress had no tax - setting power).

Answer:

The national government was unable to collect taxes.
