"National" should be without a capital letter.
From the Portuguese word for flag bandeira.
What has this sentence got to do with schools?
Students typically raise the national flag and sing the national anthem at school assemblies at least once a week, weather permitting, in Tanzania. Furthermore, the colors of the flag, and their meaning, are common questions on civics examinations.
Thank you for answering!
Although, it was a rhetorical question. Flag-worshipping in schools just makes me uncomfortable. Some countries take it too far. Hopefully not Tanzania!
