Question 7
(Advanced Deduction and Inference)
Age 10 and Over
North starts play and
wins the first three tricks with Ace of Spades, King of Spades and
Queen of Spades. All other players follow suit to all three tricks. At
trick four North plays the two of diamonds.
What can we deduce
and what can we infer
from all this?
(a) We can deduce
that all the spades have been played and infer
that
North does not have the Ace of Diamonds
(b) We can deduce
that there is one spade left
un-played and infer
that North does not have the Ace
of Diamonds
(c) We can deduce
that there is one spade left
un-played and infer
that South has it
(d) We can deduce
that there is one spade left
un-played and infer
that North does not have it
