During the 19th century, the United States ability to remain isolated from European affairs was largely due to its "geographic location," since it is bordered by the two largest oceans in the world.
Watch your words about security measures or the enemy may use them to attack American ships.
Answer: Option B.
<u>Explanation:</u>
In the poster which has been talked about, there is a ship which has been burnt and the sailors are saving their lives by rowing away in a life boat. Trying to save themselves.
The image is trying to say that we have to be very careful about what we speak and what we do. Because this might give a chance to the enemies to take advantage of the situation if they get to know our safety measures and they might try to harm us. So we have to be very careful of what we plan and how we plan and make sure that our enemies do not get any idea of what we plan.
