Answer
1(1) some square are circles.(I)+  No circle is a triangle (E) = I+ E=O Some square are not be triangles.
conclusion (a) follows
Again,  No line is a square.(E)+some square are circles.(I) = E+I=O Some circle are not line.
Hence, conclusion (b)does not follows
2 (4)some square are circles.(I)+  No circle is a triangle (E) = I+ E=O Some square are not triangles.
conclusion (a) does not follows
Again,  No line is a square.(E)+some square are circles.(I) = E+I=O Some circle are not line.
Hence, conclusion (b)does not follows
 3.(5)  All song  are poems.(A)+  All poems are rhymes(A) = A+A=A  =All song  are  rhymes.
Now All song  are  rhymes.(A) +No rhymes is a paragraph(E) = A+E=E=No song is a paragraph
 conclusion (a) follows
Again All poems are rhymes(A) +No rhymes is a paragraph(E) = A+E=E=No poem is a paragraph.
 Hence, conclusion (b) follows
4.(2) All poems are rhymes---->conversion -------->Some rhymes are poems.
Hence, conclusion (a)does not follows
 All song  are poems.(A)+  All poems are rhymes(A) = A+A=A  =All song  are  rhymes.
   Hence, conclusion (b) follows
5.Some dews are drops.(I)+ All drop are stones(A)=I+A=I=  Some dews are stone   it means At least some dews are stones    Hence, conclusion (a) follows  &  conclusion (b) follows by converting the second statement.
