The statement that best contrasts general obligation bonds and revenue bonds used to fund different levels of government in Texas is:
General obligation bonds use taxes to pay back debts, while revenue bonds use revenue from public works.
This accurately reflects the fundamental difference between the two types of bonds: general obligation bonds are backed by the taxing power of the issuer (usually a municipality or state), while revenue bonds are repaid from the income generated by specific projects or services such as tolls, fees, or service charges.
