Step 1: Read off the two given rows.
Above the line: B, C, D, E, J, K, L, M. Below the line: A, F, G, H, I, N.
Step 2: Group the full alphabet into blocks, starting with the single letter A.
Writing the alphabet out gives: A, then BCDE, then FGHI, then JKLM, then NOPQ, then RSTU, then VWXY, then Z.
Step 3: Match each block to a row.
A sits alone below the line. BCDE sits above the line, matching the given "B C D E". FGHI sits below the line, matching the given "F G H I". JKLM sits above the line, matching the given "J K L M".
So the blocks alternate below, above, below, above, and so on: A (below), BCDE (above), FGHI (below), JKLM (above), NOPQ (below), RSTU (above), VWXY (below), Z (above).
Step 4: Locate W inside this pattern.
Numbering the blocks in order, A is block 1, BCDE is block 2, FGHI is block 3, JKLM is block 4, NOPQ is block 5, RSTU is block 6, VWXY is block 7, and Z is block 8.
The odd-numbered blocks (1, 3, 5, 7) sit below the line, and the even-numbered blocks (2, 4, 6, 8) sit above the line, exactly matching the pattern already given.
The letter W belongs to block 7 (V, W, X, Y), which is an odd-numbered block.
Final Answer:
Since block 7 sits below the line, W must go below.
\[ \boxed{\text{Below}} \]
