Matching the dates to the event timeline is key. The events in the prompt occur in two specific years that fit the described sequence and any implied interval. The pair 1986 and 1990 preserves the stated timing between events, aligning with the timeline given in the question. The other year pairs place an event outside the described window or disrupt the interval, so they don’t match the events as described. So, 1986 and 1990 is the pairing that fits the described timeline.
