Final answer:
Dillon's Rule limits local government powers and does not provide them with autonomy, and proprietors in proprietary colonies had responsibilities beyond just collecting profits. Both reference statements are false.
Step-by-step explanation:
The statement that officers are able to release property to the rightful owner without sending it to P E may require some context to understand what is specifically meant by 'P E.' However, without the proper context, it's difficult to ascertain the truthfulness of the statement. Now, regarding the provided reference statements:
Dillon's Rule does not give local governments the freedom and flexibility to make decisions for themselves. This is because Dillon's Rule states that local governments are limited to those powers expressly granted to them by the state government or those powers closely linked to the express powers. As such, it limits local governments rather than providing them with flexibility. Therefore, the answer to the first reference question is False.
In a proprietary colony, the proprietors had responsibilities beyond just collecting profits. Proprietors were responsible for establishing the colony's government and making decisions for the welfare of the colony, among other duties. As such, the assertion that proprietors only have to collect profits is incorrect, making the answer to the second reference question also False.
