The survey return tray

An original notice containing five intentional errors.

The tray are beside the information desk throughout the exhibition. Respondent's can chose to leave a name or return the form without one. Please distinguish the session you attended from a diffrent event you heard about later. The organiser will keep those kinds of comment separate when reviewing the results. A succesful trial should not be claimed solely because the people most willing to complete a form enjoyed it.

Proofread the notice. Identify the five errors and write the correct forms. You do not need to rewrite the whole passage.
