>>213785848No, she wouldn't have to check the basket because it would be apparent without having to check.
>>213785915She doesn't have to look in it, she only has to look at it, so she doesn't have to check the basket, she just has to enter the room with the basket to know if it has a marble, so there is no possible way to check the box first anyway since it has to be opened to check if the marble is there, so the question makes no sense if that is the case because everyone would always see the basket before they could check the inside of the box, its not possible to do it any other way.
