Question

Japan's annexation of Korea led to the Russo-Japanese War.
a. True
b. False.

Answer 1

Let's look at the timeline of these events:

The Russo-Japanese War took place in 1904-1905.

Japan's annexation of Korea took place in 1910.

So the second could not have been the cause for the first, rather the other way round!

So the statement is false.
