An Assembling Objects fitting-parts question shows several disassembled pieces (like puzzle pieces) and four answer figures showing one possible assembled shape each. Your job is to find the answer where:

FITTING-PARTS questions present 4-5 disassembled pieces (each a 2D shape) and ask which assembled figure they form. Rules: (1) ALL pieces must be used; (2) Pieces fit TOGETHER WITHOUT OVERLAPPING (no piece on top of another) and WITHOUT GAPS (no empty spaces inside the assembled outline); (3) Pieces CAN be rotated (turned to different angles); (4) Pieces CAN be flipped (mirrored — picked up and turned over); (5) Piece sizes and shapes are PRESERVED — you cannot stretch, shrink, or distort pieces. Wrong-answer patterns to watch for: (a) An assembled figure that's the right shape overall but requires altered piece sizes (e.g., one piece would need to be smaller); (b) A piece is missing from the assembly (unused); (c) A piece appears twice; (d) Pieces overlap in the assembly; (e) Gaps remain inside the assembled shape; (f) The overall outline doesn't match what the pieces could form.

Strategy: (1) Count distinctive features of the pieces — sharp angles, long edges, curves, unique shapes — and look for them in the answer figures; (2) Look at TOTAL AREA — the assembled shape should have the same total area as the sum of the piece areas (you can roughly judge this by eye); (3) Match distinctive piece edges to answer outlines; (4) Eliminate answers with obvious errors first; (5) Don't spend too long on any one question — pick the best fit and move on if stuck.

Key mental skill: practice 'mental jigsaw' — visualizing rotating and flipping pieces in your head. With practice this becomes faster. Many candidates find these questions easier than connecting-points after some practice.
