D. Honey was a common sweetener but sugar was easier to harvest.
I don't really understand the poem. I can tell you a couple of thing about the poem that remind me of the outsiders. In the outsiders Ponyboy and the other kid (his name escapes me) ran away after he stabbed another kid. This reminded me of when the poem said "They'd banish -- you know!" because the reason they ran away is so they wouldn't get arreste so I think being banished is sort of like being arrested. I hope I helped. Please give me the brainliest.
The answer is D.
"Keep", "factor", and "calculate" are all verbs in the list of things the new system allows teachers to do. The other sentences are inconsistent with their list of verbs/adjectives/nouns. Thus, option D is the only one that is grammatically correct.
I am not too good at explaining, so let me know if you are still confused.
Hope this helps! :)
