Hint 2 of 2
Notice that one card shows the sun AND ducks — use that to free up the plain sun card.
Show solution
Approach: assign cards by elimination
  1. Lexi gets the dog card and Heidi gets the kangaroo card.
  2. Paula needs exactly two animals — the ladybird-and-fly card.
  3. The duck card also shows a sun, so Clara's 'sun' card is that one, not the plain sun.
  4. That leaves the plain sun card (no ducks) for Michael: A.
