Explanation:

First Sub - Question (Abraham Lincoln was elected president in ____)

Abraham Lincoln was elected as the president of the United States in 1860. From the given list, 1860 is the relevant option that fits the context of his election year.

The Southern states seceded from the Union mainly to protect slavery and also the concept of states' rights (which was related to their ability to maintain slavery and have more control over their internal affairs). Among the given options, "slavery" or "states' rights" could be considered, but more directly, they seceded to protect slavery (as states' rights was often a guise to protect the institution of slavery). However, from the list, "slavery" is a repeated and relevant option, and also "states' rights" is relevant. But historically, the primary motivation was to protect slavery.

Answer:

1860
