Hi tanvis1120,

This CR prompt describes a circular/repeating cycle that occurs when people evade paying taxes...

1) People avoid paying income taxes
2) Lawmakers are FORCED to raise income taxes
3) The tax burden becomes worse for people who actually pay tax, so....we end up back at Step 1....

1) More people avoid paying income taxes
Etc.

We're essentially asked to define WHY this cycle happens. When reading the prompt, I focused on the word "forced" - why EXACTLY would lawmakers be FORCED to raise taxes if some people didn't pay??? There must be some "need" for that money; when the lawmakers don't get what they need, then they have to raise taxes to try to get what they need. We're looking for an answer that addresses this issue (and likely points out something faulty in the lawmakers plan that causes the problem to occur).

Answer C gives us exactly what we're looking for. The root "cause" of the cycle and the reason why it occurs.
