**Correct answer:**

Even

When trying to decide if we have an even or an odd number of items, we can put the items in pairs of two. If each item is in a pair, then we have an even number of items. If there is one item that isn't in a pair, then we have an odd number of items.

In this case, our dots are in pairs of two, so we have an even number of dots.
