1) Is it just me or is the audio not working?
2) I see a double m in mmarekani. Quite different from the other nationalities: mtanzania, machina, mkenya, mholanzi.
3) In the exercise, I came across two nationalities that had the first letter in uppercase. Mmarekani and Mchina. Are there rules for nationalities or can they be written in any way? Are both Mmarekani and mmarekani and Mchina and mchina correct?
