Q7: Zan iya samun girma dabam dabam?
Eh za mu iya ba ku diamita na musamman, tsayi da maki don aikinku.
Q8: Yadda ake zaɓar maki mai kyau?
Dangane da ƙarfin kaya, yanayin ƙasa da amfani da gini. Taimako daga injiniyanci.
Q9: Menene lokacin isarwa na yau da kullun?
Kwanaki 15-30, ya danganta da yawa da kuma keɓancewa.
