get variables in two separate lines

I have the file ole.txt:

A   B   C
1   2   3
a   b   c
11  22  33

with option A:

cat ole.txt | sed -n -e 1p -e 3p

we get:

A   B   C
a   b   c

with option B:

sox=$(cat ole.txt | sed -n -e 1p -e 3p)
echo $sox

we get:

A B C a b c

How can I change the code in option B to get the result in option A (the result as 2 rows)?

And what's the problem with option A? why you need to keep all the data of a file inside a variable ?!

PS: And I'll tell you, don't play with the white-space characters inside a variable; you are definitely going to burn and it hurts.

PPS: This is happening because the bash shell splits the words on white-space character (spaces, newlines, tabs). I'd recommend not to save data of a file inside a variable. But if you insist, here is the solution

First, I'd use a shorter command. You may check that this command is equivalent 

sed -n '1p;3p;' ole.txt

Now

sox="$(sed -n '1p;3p;' ole.txt)"
echo "$sox"
