because it happened in 1846
Answer:
1.The closing of the Suez Canal by Egypt in 1956.
2.The OPEC oil embargo in 1973.
Explanation:
Most of the world's oil reserves and supply come from the Middle East. It is estimated that about 64.5 % of the world's oil supply is from the Middle East nations, making it an important aspect of the world's crude oil supply.
If these reserves or supplies were to be stopped or banned by the OPEC nations, or any of these majority supplying nations were to stop their export, then there will be a vast 'disaster' or rather 'crisis' in the nations that depend on these supplies. So, events such as <u>the 1956 closing of the Suez Canal by Egypt or the OPEC oil embargo of 1973 are proof that the Middle East nations could threaten the world's oil supply.

Thus, the correct answers are options 1 and 2.
