Matambudziko anotevera anofanira kutariswa kana achishandisa retarder mune yekutengesa kongiri:
A. Teerera kutarisisa kuenderana neyakajairika system system uye mamwe emakemikari admixture.
B. Teerera kune shanduko mune tembiricha yemamiriro ekunze
C. Teerera kufambira mberi kwekuvaka uye kufambisa chinhambwe
D. Teerera kune izvo zvinodiwa chirongwa
E. Kutarisirwa kunofanirwa kubhadharwa kusimbisa kuchengetedza nguva
