Which of these words clues the reader that the author is using chronological order to organize the writing?
a. in addition,
b. because
c. next
d. on the other hand,

The correct answer is:

C. Next

Explanation:

Authors in their texts usually use text structures to organize their writings. In this case if the author wantsto clue the reader about something in chronological order he should use a "Sequential Text Structure". In this text structure the transitional words we find are: first, next, then, finally, before, by the time, soon, meanwhile. That's why next is the correct answer choice.

my best guess would be: d allusion

makes the most sense
