Final answer:
True, governors can use a line-item veto to approve parts of a bill.
Step-by-step explanation:
True, a governor is allowed to use an item veto to approve only parts of a bill. Specifically, this is known as the line-item veto, which enables governors to veto particular items within appropriation bills, while allowing the rest of the bill to become law. However, it's important to note that the legislature may override a line-item veto with a two-thirds vote.
Furthermore, some states have limited or altered the scope of such veto powers, as seen in the example of Wisconsin with the "Vanna White" and "Frankenstein" vetoes.
