What was one major weakness with the articles of confederation?

It created a too-weak national government.  

When Congress drafted the nation's first constitution in 1777, it knew that many Americans feared a powerful national government. For that reason, the proposed Articles of Confederation created a framework for a loose confederation of states. Within this alliance, each state would retain "sovereignty, freedom, and independence." Any power not specifically given to Congress was reserved for the states. This meant that each state could often develop its own policies.

In addition, the Articles did not set up an executive branch to carry out the laws or a judicial branch to settle legal questions.

so d is the answer

the correct answer is: (1) affected by gerrymandering; (2) not affected by gerrymandering.

gerrymandering is known as a practice that intends to establish a some kind of political advantage for a particular party or group. to do this district boundaries are manipulated. the new resulting district is named a gerrymandering.

in other words, what gerrymandering does is to draw the boundaries of electoral districts trying to benefit the party who is doing it. sometimes, the party controlling the legislature will redraw it so they can maximize the number of districts they are likely to control.
