Nangona izilwanyana nezityalo ezifumaneka kwiintlango zizininzi njengezo zifumaneka emahlathini, abaphandi bathi “into yokungakhathalelwa kwezinto eziphila kwiintlango icaca ekungaxhasweni kwazo ngokwezimali.” Ngenxa yoko, kunzima ngoososayensi ukuzibek’ esweni izityalo nezilwanyana zasentlango ezisengozini.
