Answer and Explanation:
The chart shows the number of Dreadnoughts constructed by Britain and Germany during the 1910s. In the "Britain" column, the entries indicate that they constructed 7, 3, 5, 3, 7, and 3 Dreadnoughts in the years Pre-1910, 1910, 1911, 1912, 1913, and 1914, respectively. In the "Germany" column, the entries indicate that they constructed 7, 1, 3, 2, 3, and 1 Dreadnoughts in the same respective years.
By comparing the number of Dreadnoughts constructed by Britain and Germany, we can see that Britain had a higher number of Dreadnoughts built in each year compared to Germany. Therefore, based on this chart, it can be concluded that Britain won the naval arms race during the 1910s, as they constructed more Dreadnoughts than Germany during this time period.
