"They are looking for strawberries."
Translation:Вони шукають полуницю.
"Суниця" is another common word for strawberries in Ukrainian and probably the more proper term for this fruit.
These are actually two kinds of strawberries.
Полуни́ця is much larger, the kind you usually buy in shops:
While суни́ця is the smaller kind you usually look for in the forest (although there are garden varieties too, but still they're normally smaller than полуни́ця):
But I agree that both words should be accepted, since English normally doesn't make this distinction.
