For this question, is the support found around Lines 43-45 where it said eventually it emerged into "mature writing". I found this passage particularly hard to follow on what exactly the evolution was but my sense is that the tokens started out as really abstract (e.g. the sheeps in line 6) and then over time became more concrete? The passage was never really clear on what exactly it means to be "abstract" and we had to infer some things were indeed abstract
What we call this development a prelude into the modern languages though? The main point question, Q15, has Choice "D" as an incorrect answer choice but it described the evolution as one that became a modern language.
