Exemplars (from the NaCCA curriculum)

E.g. 1. Explain first-hand data as data that you collect on your own; and second-hand data is data that has been collected and organized by somebody else.
E.g. 2. Mrs. Acquaye's class studied the weather. The learners measured the rainfall for 5 days (Monday to Friday). For her class these results are first-hand data. But for another class these results are second-hand data. The document prints this indicator's code and text run together as "B5.4.1.1.1Explain the difference between first-hand and second-hand data.", with no space, which is why INVENTORY.md misses it.
