Bangaki abantu abavakashela i-zoo e-United States unyaka ngamunye?
Context:I-zoo (isifushaniso segama elithi zoological garden; eliphinde libizwe ngokuthi ipaki yezilwane noma i-menagerie) yisikhungo lapho izilwane zigcinwa khona ngaphakathi kwezindawo ezivalelwe ukuze ziboniswe umphakathi futhi zivame ukuzalaniswa ngezinjongo zokulondolozwa.  Igama elithi ingadi yezilwane lisho isayensi yezilwane, okuwukuthi, ukucwaninga ngezilwane. Leli gama lisuselwa egameni lesiGreki elithi ζώον, zoon, 'isilwane,' kanye nesijobelelo esithi -λογία, -logia, 'isifundo'. Isifushaniso esithi zoo saqala ukusetshenziswa lapho kukhulunywa ngeLondon Zoological Gardens, eyavulwa ukuze kufundwe isayensi ngo-1828 futhi yavulelwa umphakathi ngo-1847. E-United States kuphela, iziqiwi zivakashelwa abantu abangaphezu kwezigidi ezingu-181 unyaka ngamunye.
Abantu abayizigidi ezingu-181 e-U.S. bavakashela i-zoo minyaka yonke.
