Set M contains numbers that satisfy the condition that, if integer x is in the set then x+1 will also be in the set M. If 0 is one of the value in the set, which of the following numbers must also be present in the set M.
I. 1
II. 3
III. 2
Pick:
A) I only  B) II only  C) I and II only  D) II and III only  E) I, II and III
Notice that we are askedwhich of the following numbers MUST also be present in the set MnotCOULD be in the set.   Now, if 0 is in the set, then 0+1= 
<gadget id="calculator">0+1</gadget>
<output>1</output>
1mustbe in the set. Since 1 is in the set then   1+1= 
<gadget id="calculator">  1+1</gadget>
<output>2</output>
2mustbe in the set, also 3.   Answer: I, II and III.
