  12. (c) considering BDE, we find that to draw conclusion from BD, they have to recordered as DB, i.e., all shrubs have roses + all roses have nectar = all shrubs have nectar (A + A = A). Hence BDE are logically related.
  13. (a) considering DFA, to draw conclusion from DF, they have to be aligned and reordered as all springs are autumus + no autumns are seasons (After converting) = no spring is season. hence, DFA are logically related.
  14. (c) set of satements given by C is valid.
  15. (d) A + A = A. Hence, all pilots are trained + all who are trained are professional = all pilots are professional.
