Answer:
Option: A. Germany invaded the neutral country of Belgium.
Explanation:
Great Britain stepped into World War I when Germany invaded Belgium. Britain had promised to support Belgium under the Treaty of London of 1839. Belgium was a neutral country which guaranteed protection from Britain. The Germans wanted the British to ignore the treaty and let them pass through Belgium. The British protect Belgium because its ports were close to the British coast. German control of Belgium would have been a threat to Britain. The British wanted to crush Germany's military capability as they entered into the war.
I think it would be the first couce
The transatlantic slave trade began during the 15th century when Portugal, and subsequently other European kingdoms, were finally able to expand overseas and reach Africa. The Portuguese first began to kidnap people from the west coast of Africa and to take those they enslaved back to Europe.
I think that Hitler saw in Austria the chance to increase the number of loyal, German soldiers - Austrians speak German and are culturally similar so it was easy to include them into the German army and so quickly acquire a great number of loyal soldiers who spoke the language and shared the culture with the Germans.
