III.1  Select the correct option
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 -3 is in the set, then -3+3= 
<gadget id="calculator">-3+3</gadget>
<output>0</output>
0mustbe in the set. Since 0 is in the set then   0+3= 
<gadget id="calculator">  0+3</gadget>
<output>3</output>
3mustbe in the set and 6 also. Could -8 or 1 be in the set? sure no.   I onlynswer: I only.
