Problem: Teeth (singular tooth) are small whitish structures found in the jaws (or mouths) of many vertebrates that are used to tear, scrape, milk and chew food. Teeth are not made of bone, but rather of tissues of varying density and hardness, such as enamel, dentine and cementum. Human teeth have a blood and nerve supply which enables proprioception. This is the ability of sensation when chewing, for example if we were to bite into something too hard for our teeth, such as a chipped plate mixed in food, our teeth send a message to our brain and we realise that it cannot be chewed, so we stop trying.
What are teeth used for?
The answer is the following: to tear, scrape, milk and chew food

Problem: Nationalists have conflicting views about the language(s). The nationalists among the Croats conflictingly claim either that they speak an entirely separate language from Serbs and Bosnians or that these two peoples have, due to the longer lexicographic tradition among Croats, somehow "borrowed" their standard languages from them.[citation needed] Bosniak nationalists claim that both Croats and Serbs have "appropriated" the Bosnian language, since Ljudevit Gaj and Vuk Karadžić preferred the Neoštokavian-Ijekavian dialect, widely spoken in Bosnia and Herzegovina, as the basis for language standardization, whereas the nationalists among the Serbs claim either that any divergence in the language is artificial, or claim that the Štokavian dialect is theirs and the Čakavian Croats'— in more extreme formulations Croats have "taken" or "stolen" their language from the Serbs.[citation needed]
What opinions do Croatian Nationalists have on the language issue?

The thousands of African Americans who came to Detroit were part of the Great Migration of the 20th century.
