1. All Members of Group IV include all members of Group II.
2. All Members of Group III include all members of Group I.
3. All Members of Group IV include all members of Group I.
4. All Members of Group II include all members of Group I.
5. All Members of Group III include all members of Group IV.
Which of the following statements must be true in order to establish that Group III is the all-embracing group, that is, includes Groups I, II and IV?
(A) Statement 1 is a vital piece of information.
(B) Statement 2 is a vital piece of information.
(C) Statement 3 is a vital piece of information.
(D) Statement 4 is a vital piece of information.
(E) None of the above statements is a vital piece of information.
IMO it should be statement 5 that is vital, but since there isn't an option, I picked E. Answer is A somehow. I disagree.

Which of the following statements must be true in order to establish that Group II is the all-embracing group, that is, includes Groups I, II and IV?
At a loss, cos I can estb Group I is all encompassing'& other are subsets.
1. All Members of Group IV include all members of Group II.
4. All Members of Group II include all members of Group I.
Either IV is a subset of II from 1. , then II is a subset of I from 4. or
or II is a subset of IV and from 1.
one of the interpretation has to be correct then II will be a subset.
Are u able to estb that Group II is the biggest group ? If so how ?

I apologize, the question was supposed to say III in your highlighted area. The changes have been made on the original question.kstv wrote:Which of the following statements must be true in order to establish that Group II is the all-embracing group, that is, includes Groups I, II and IV?
