(20 12? The Wayne diagram of the relationship between the complete set U=R and the set M={x∈R

The set shown in the shaded part of the figure is m ∩ n.

∫ m = {x ∈ r |-2 ≤ x-1≤ 2} = {x ∈ r |-1≤ x ≤ 3}, and N={x|x=2k, k∈Z}

∴M∩N={0,2}

Therefore, there are two elements in the collection * * * displayed in the shaded part.

So choose B.
