Context and question: Canada has the world's largest deposit of natural bitumen in the Athabasca oil sands and Canadian First Nations along the Athabasca River had long used it to waterproof their canoes. In 1719, a Cree Indian named Wa-Pa-Su brought a sample for trade to Henry Kelsey of the Hudson’s Bay Company, who was the first recorded European to see it. However, it wasn't until 1787 that fur trader and explorer Alexander MacKenzie saw the Athabasca oil sands and said, "At about 24 miles from the fork (of the Athabasca and Clearwater Rivers) are some bituminous fountains into which a pole of 20 feet long may be inserted without the least resistance."
Which country has North America's largest deposit of naturally occurring bitumen?

Question: Illegal pinning methods include using the ropes for leverage and hooking the opponent's clothing, which are therefore popular cheating methods for heels, unless certain stipulations make such an advantage legal. Such pins as these are rarely seen by the referee (as they have to see if their shoulders are down) and are subsequently often used by heels and on occasion by cheating faces to win matches. Even if it is noticed, it is rare for such an attempt to result in a disqualification (see below), and instead it simply results in nullification of the pin attempt, so the heel wrestler rarely has anything to lose for trying it, anyway.
Is there an answer to this question: What is a pinning method that isn't allowed?

Answer: using the ropes for leverage and hooking the opponent's clothing,


QUES: The Scottish traveler James Bruce reported in 1770 that Medri Bahri was a distinct political entity from Abyssinia, noting that the two territories were frequently in conflict. The Bahre-Nagassi ("Kings of the Sea") alternately fought with or against the Abyssinians and the neighbouring Muslim Adal Sultanate depending on the geopolitical circumstances. Medri Bahri was thus part of the Christian resistance against Imam Ahmad ibn Ibrahim al-Ghazi of Adal's forces, but later joined the Adalite states and the Ottoman Empire front against Abyssinia in 1572. That 16th century also marked the arrival of the Ottomans, who began making inroads in the Red Sea area.

What determined whether The Bahre-Nagassi fought with or against the Abyssinians?
