Question

In each question, there are three statements followed by two conclusions numbered I and II. You have to take the three given statements to be true even if they seem to be at variance with commonly known facts and then decide which of the given conclusions logically follows from the given statements disregarding commonly known facts.

Statements:-
Some Ds are Gs.
All Gs are Ks.
All Ks are Ls.

Conclusions:-
I. At least some Ds are Ls.
II. All Gs are Ls.

• A. Only conclusion I follows
• B. Only conclusion II follows
• C. Either conclusion I or conclusion II follows
• D. Neither conclusion I nor conclusion II follows
• E. Both conclusions I and II follow
  
  

Answer 1

The correct option is E Both conclusions I and II follow



Mediate term of the following statement is
Some Ds are Gs (I - type)
All Gs are Ks (A - type)
$I+A\to Itype$
Some Ds are Ks
Another mediate term is
All Gs are Ks (A - type)
All Ks are Ls (A - type)
All Gs are Ls (Conclusion II follows)
Another possible mediate term is
Some Ds are Ks (I - type) [From Eq. (i)]
All Ks are Ls (A - type)
$I+A\to I-type$
Some Ds are Ls (Conclusion I follows)

Both conclusions I and II follow
