Commentary:
In Question 2, the most correct response was 1981. Only 24% of students chose that response. Visually, the correct response was 1978, chosen by 35% of students. Both counted as correct in the above table.

Question 3 proved particularly demanding. Many answers were quite vague; others focused on details that were much less important than the major trends.
