5
Is the Klein 4-Group a cyclic group? (a) Yes (b) No
6
What is the first line in this proof? (a) Assume G is an abelian group. (b) Assume G is a cyclic group. (c) Assume a * b = b * a.
7
What is the next line in this proof? (a) Then G is abelian. (b) Then G contains inverses. (c) Then a * b = b * a for all a, b in G. (d) Then G = for some x in G.
8
What is the next line in this proof? (a) Choose any two elements of G. (b) Then G has finite order. (c) Then a * b = b * a for all a, b in G. (d) Choose any element x and its inverse.
9
What is the last line in this proof? (a) Thus G is abelian. (b) Thus G contains inverses. (c) Therefore G is cyclic. (d) Then G has primary order.
10
What is the second to last line in this proof? (a) Then G is cyclic. (b) Then G has finite order. (c) Then a * b = b * a for all a, b in G. (d) Choose any element x and its inverse.
