The vES ending should be added to nouns that end in -f or -fe in their singular form. In that case, the -f or -fe is removed and -ves is added as a plural ending. Examples include: life - lives, wife - wives, knife - knives, wolf - wolves, leaf - leaves. But there are also exceptions, such as belief - beliefs, cliff - cliffs, roof - roofs.
If I were to create a poster that explains positive culture group interactions, I would split it into four different sections. In the first section, I would describe what a culture group is (a group with shared attitudes, values, goals, and practices). In this section, I would include images that reflect culture groups from different countries. In the second section, I would discuss the idea of knowledge of culture. In this section, I would explain that knowledge of my culture and the other person's culture is key to having a positive culture group interaction. I would also use images of a library, which is a place where knowledge is kept. In the third section, I would discuss needs and feelings of people involved in a culture group interaction. In this section, I would explain that it is important to remember the needs and feelings of each person involved in a culture group interaction. I would also include an image of two people talking. In the fourth section, I would have no words but rather one image of two people with their arms around each other. This would reflect that positive culture group interactions create friendships.
