Step 1 of 4

Find the wrong step

Find where the reasoning first breaks

Start with Step 1 and move downward. Choose the first line that stops making sense.

Later lines may be wrong too. Pick the first mistake.

Lumi’s work

These lines form one solution. Read them from top to bottom.

  1. 1

    The opening words tell us when the event happened.

  2. 2

    The main event is: the dinosaur sneezed.

  3. 3

    Opening information never needs a comma before the main event.

  4. 4

    Write: After the museum closed the dinosaur sneezed.
