"Wamarekani" is plural. Shouldn't the correct answer have "Americans" to be consistent?
"Your guests are Americans" is accepted as an alternative translation for this sentence, because "Wamarekani" can be understood as an adjective or a noun.
So if I understand correctly, the "you" that is used in this sentence is plural, right? The Americans are the guests of plural addressees?
Thank you! That's very helpful.
