I think you made a mistake in your question. The word "veto" would be replaced by the word "vote". I am writing the answer based on the change in the word. It would be absolutely true to say that if the house makes changes, the bill goes back to the original house for a vote. The correct option among the two options in the question is the first option.
The Romans would develop road systems as they went along with their expansion. Every time they'd conquest new territory, they'd make sure to keep the new colonies controlled by facilitating access to them through the construction of new roads. In addition, the development of these routes was crucial to containing attacks and ensuring a successful defense of the Empire, as the armies would move move faster and arrive quickly to the territories in conflict.
This strategic emphasis in roads and bridges was vital to the success of their army. The routes were built specifically with speed of movement in mind, designing them mostly in straight lines for efficiency.
Hope this helps!
