Final answer:
Germany decided to rearm in secret to bypass the restrictions imposed by the Treaty of Versailles, defend against potential threats, and avoid international scrutiny.
Step-by-step explanation:
Germany decided to rearm in secret for several reasons. First, the Treaty of Versailles imposed strict restrictions on Germany's military capabilities, including the size of its army and the type of weapons it could possess. By rearming in secret, Germany could bypass these restrictions and build up a strong military force. Second, Germany felt the need to defend itself against potential threats, such as the growing power of other European nations. By rearming in secret, Germany could surprise its adversaries and gain an advantage in any future conflicts. Lastly, rearming in secret allowed Germany to avoid international scrutiny and avoid provoking a strong response from other countries.
