Mibvunzo Inowanzo bvunzwa
1. Ndeupi musiyano uripo pakati pemutauri wehoni yePA nenzwi remuindasitiri?
Mutauri wePA horn unowanzo shandiswa kutungamira uye wakagadzirirwa kuratidza manzwi ari kure. Mutauri weindasitiri anogona kushandisa nzira yakasiyana yekutaura kuti anzwike zvakanaka mukati meimba.
