Each year, nearly $200 million in hunters' federal excise taxes are distributed to state agencies to support wildlife management programs, the purchase of lands open to hunters, and hunter education and safety classes. Since 1934, the sale of Federal Duck Stamps, a required purchase for migratory waterfowl hunters over sixteen years old, has raised over $700 million to help purchase more than 5,200,000 acres (8,100 sq mi; 21,000 km2) of habitat for the National Wildlife Refuge System lands that support waterfowl and many other wildlife species and are often open to hunting. States also collect money from hunting licenses to assist with management of game animals, as designated by law. A key task of federal and state park rangers and game wardens is to enforce laws and regulations related to hunting, including species protection, hunting seasons, and hunting bans.

Ah, so.. 5,200,000 acres

Navigation is based on a variety of senses. Many birds have been shown to use a sun compass. Using the sun for direction involves the need for making compensation based on the time. Navigation has also been shown to be based on a combination of other abilities including the ability to detect magnetic fields (magnetoception), use visual landmarks as well as olfactory cues.

The report "Mary: Faith and Hope in Christ", by the Anglican-Roman Catholic International Commission, concluded that the teaching about Mary in the two definitions of the Assumption and the Immaculate Conception can be said to be consonant with the teaching of the Scriptures and the ancient common traditions. But the report expressed concerns that the Roman Catholic dogmatic definitions of these concepts implies them to be "revealed by God", stating: "The question arises for Anglicans, however, as to whether these doctrines concerning Mary are revealed by God in a way which must be held by believers as a matter of faith."
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of interpretation did the group believe was of concern in regard to Mary ?
Ah, so..
The question arises for Anglicans, however, as to whether these doctrines concerning Mary are revealed by God in a way which must be held
