Question: Which of these events occurred first?

d. Britain blockaded Germany.

d) Britain blockaded Germany

Explanation:

I just took the edg-enuity test and this was correct. But here's an actual explanation:

Britian blockaded an important shipping route to prevent the Central Powers from getting supples, which led to the stalemate being broken, then Germany was forced to retreat after being surprised at Amien, then the armistice was signed. So really, the only option would have been D.

Hope this helped!
