This puzzle contains pairs of pictures which differ from each other by a single letter. Solving the puzzle requires correctly naming the pairs and recording the changed letters:
CHEAT/CHEST – A/T
STONE/STOVE – N/V
PISCES/PIECES – S/E
WINK/LINK – W/L
SHOEING/SHOVING – E/V
TRAM/TEAM – R/E
SIEVE/STEVE – I/T
Reading down the unique letters in columns gives “ANSWERI” and “SVELVET”, so the answer is VELVET.
