Question 1193128
<pre>

If we temporarily consider two people "A" and "B" as a unit, we have essentially four people to seat: { {AB}, C, D, E }

Four people can be seated at a circular table in 3! = 6 ways.

Now we must double it for {AB} and {BA} are two unique arrangements:

2*6 = {{{ highlight( 12 ) }}} ways to seat five people such that two of them are always together.
