#1**0 **

One

When calculating the number of objects that are in pairs, the correct answer is one. For instance, if there are 11 pairs of socks and each pair has 2 pairs of shoes, then the result of adding 2 to 11 is 22. This is equal to 1 pair plus 1 sock. Similarly, adding 2 to 11 gives 22 pairs of shoes, which is 1 pair plus 1 shoe. In both instances, the result of 2 to 11 is 1 unit, even if the total of the items is greater than 1.
