Here's a little challenge from one who seldom uses TeX because of the
frustration of not having a local guru to ask how to do
moderately complicated things. The answer may be easy. If it
is I apologise.

I wish to typeset something like the following

1. Item 1                                 Explanation 1
2. Item 2                                 Explanation 2
3. Item 3 \
4. Item 4 |                               Explanation to 3,4 and 5
5. Item 5 /
6. Item 6                                 Explanation 6

where some of the items are bracketted as shown.

The trouble is that I want the lefthand ends of all the items to be
aligned and similarly with the explanations. To get the bracket I have to
go into math mode. How do I align items 1, 2 and 6 (outside math mode)
with 3,4 and 5 (in math mode)? LaTeX preferred but TeX would do.
