Fa'amatalaga
1) o faʻamatalaga faʻapitoa uma o loʻo faʻaalia i luga e mo lau faʻamatalaga.
2) e talia nisi fa'amatalaga mo nisi talanoaga.
Fa'asinomaga
O loʻo avanoa le gaosiga faʻapitoa mo faʻaoga eseese e faʻatatau i lau manaʻoga faʻapitoa.
Matou te maua le poto masani R & D, ma le gaosiga o matagaluega, e mafai ona atiina ae ma faʻataʻitaʻiga-faia mea fou ma faʻamatalaga e tusa ai ma le manaʻoga faapitoa.
