Question

The passage details several events in Dr. Harrison's career and research. Read the passage and arrange the events below in chronological order from earliest to latest:

"It was not until the summer of 1994, when Dr. Harrison first unearthed the obsidian seal in the ruins of Carchemish, that the fragmented timeline of the Hittite scribe began to cohere. Years later, in a draft of his memoirs completed just before his retirement in 2018, he recalled the cold autumn evening of 2002 when he had finally decoded the third register of the seal. That evening, as rain lashed against his study window, Harrison was reminded of a warning his mentor, Professor Vance, had delivered during their first joint survey of the Euphrates valley in 1985. Vance had cautioned that the 'scribe of the seals' often recorded events decades after they occurred, muddying the chronological waters. This warning proved prophetic when, in 2012, carbon dating of the organic layer overlying the seal's original strata forced researchers to revise their estimates of the scribe’s active period, placing it much earlier than the 1994 excavation reports had hypothesized."
