| And i think it would. I think a lot of people would ask the
| invigilator to see if something is wrong with the test, or

| cat question too or get confused and give up.
|

| So when they add extra bits people's minds desperately try to

|
| But the point is not that i'm right. Maybe i'm totaly wrong.
