flesh - ice - life - mother - sky -
space - lust - turn - leave - world
Correct answer: wall or brick
Explanation:
The terms of list are taken from Pink Floyd's famous "The Wall" album. The names of the tracks on the first LP are:
In the Flesh
The Thin Ice
Another Brick in the Wall (Part 1)
The Happiest Days of Our Lives
Another Brick in the Wall (Part 2)
Mother
Goodbye Blue Sky
Empty Spaces
Young Lust
One of My Turns
Don't Leave Me Now
Another Brick in the Wall (Part 3)
Goodbye Cruel World
As you can see, some of the words have been put into singular to make it a little bit more difficult. However, the hint "Think Pink" in the heading should make it clear that there is a connection to this album.
Since all of the words in the list can be interpreted as nouns we are looking for another noun to complete the list. The missing link is the missing tracks from the first LP which are "Another Brick in the Wall" part 1, 2 and 3. So there are two nouns to choose from: wall or brick.
