Questions about poker

A question can only have two answers, yes or no.

That is to say, only two situations can be judged.

The second question is plum blossom? be

Is the third question even? No residue possibility1357 91113.

Is the fourth question greater than 8? No, the remaining possibility is 1 3 5 7.
