2.2 ,    3.4  ,     4.1  ,     5.3  ,     6.5  ,     7.3


8.5 ; All plants are stems + All stems are flowers. All
Plants are flowers –> we can also write some plants
are flowers. Hence conclusion I follows. some plants
are trees(I) conversion  –> some trees are plant (I) +
All plants are stems =I+A  –> I =some trees are stems.
Hence ,probability of conclusion II exists.


9.2 ; Some trees are plant + All plants are stems = I+A =I =
some  trees  are  stems.  This  does  not  lead  us  to
conclusion I. Now, All plants are stems + All stems
are flowers =A+A= A = All plants are flowers .Thus, II
follows


10.1; No paper is a pencil + All pencil are black = E +A = O.
Some black are not papers. This leads to us - All papers
being black is a possibility, but all blacks being papers
is not a possible statement. Hence, possibility of II
ruled out. All kites are papers +no paper is a pencil =
A+E=E =no kite is a pencil + All pencils are black = E
+A=O = some black are not kites. Thus, possibility of
I exists.
