One issue that has caused some frustration is that the sentences do not always indicate whether it is a male or female who is speaking or being spoken to, and this has caused some errors in selecting the correct answer. I'm pretty sure Mohamed, Omar, Seth and Bob are male, and Carrie, Rosa and Judy are female. But Gjassan, Samia, Lama, Rania, Arwa, Reem and Maha are not familiar names in English, so it is not clear which gender should be used.
Also, it is weird to say, "You have a blue skirt, George," or "You do not have a white blouse, Bob." In English, most men don't wear skirts or blouses. Maybe some words for shirt and pants could be added.
