Final answer:
The statement 'They object...their plans at this late date' typically reflects a scenario where individuals or groups are expressing their opposition to changes in established plans, akin to how the Antifederalists reacted to constitutional changes.
Step-by-step explanation:
The phrase 'They object...their plans at this late date' can be seen in different contexts, such as historical debates or personal objections to change in certain plans. For instance, we could refer to the Antifederalists, who objected to the change in rules, leading them to refuse to vote for delegates in ratification conventions. This indicates a scenario where objections occur due to a disagreement or dissatisfaction with the modifications introduced, especially when these changes affect established plans or expectations. Additionally, when considering plans or proposals in various settings, individuals may express objections to any alterations that could compromise their position or interests, leading to a desire to maintain the status quo and resist changes that could potentially diminish their control or benefits.
