Read columns A and B from left to right and rows 1 and 2 from top to bottom in these diagrams. Compare the same cell in both grids. Describe whether an item changed shape, changed count or moved. State the row convention instead of assuming all grids use the same one.
Worked example
If a triangle is in A2 in the first grid and B2 in the second, it moved. That does not mean an extra triangle was created. Check both its old cell and new cell.
Cargo Before and After
Before: A1 has one circle; B1 has two square crates; A2 has one triangle; B2 is empty. After: A1 has one diamond; B1 has three square crates; A2 is empty; B2 has one triangle. Use the words as an equivalent way to inspect the grids. Find three object-level changes; a move affects two cells but counts as one moved object here.
