1. Afai e fa'amaoti mai i le fa'atonuga fa'atau se fa'atagaina o le to'esea mo le mafiafia o le puipui e la'ititi ifo nai lo le tau talafeagai o lo'o tu'uina atu i lenei laulau, e tatau ona fa'ateleina le fa'atagaina o le fa'aopoopo mo le mafiafia o le puipui i se aofa'iga e lava e fa'atumauina ai le vaega talafeagai o le fa'atagaina.
2. Mo paipa e D≥ 14.000 inisi ma le t≥0.984 inisi, e mafai ona sili atu le fa'atagaina o le mafiafia o le puipui i le lotoifale nai lo le fa'atagaina fa'aopoopo mo le mafiafia o le puipui i le fa'aopoopo 0.05t pe afai e le sili atu i le fa'atagaina fa'aopoopo mo le mamafa.
