Explanation:
Assume that you have member/2 where member(X, Y) checks whether X is an element of a list Y. Complete the first clause of the following Prolog program subset/2 where subset(A, B) will establish a relationship of A being a subset of B. subset([X|R],S) :- %% the body should be... subset([ ],_).
subset([X|R],S) :-
subset([ ],_).
member(X,S), subset(R,S)
These are the supplies in the list:
[‘pencil’, ‘notebook’, ‘backpack’, ‘pen’, ‘calculator’]
Explanation:
The line return (\n) character will be in the output (so there will be a change of line), but it will NOT be visible as it would have been interpreted as a special character.
So the output will be on 2 different lines, with no \n visible.
If the command would have been: print('These are the supplies in the list:\n', supplies), with single quotes (') instead of double quotes (") then then \n would have been printed but not interpreted as a special character. At least in most computer language. Since we don't know of which language the question refers to, we can't be sure at 100%.
