QUES: The cup triumph was also Everton's passport to the Cup Winners' Cuptheir first European campaign in the post-Heysel era. Progress under Joe Royle continued in 199596 as they climbed to sixth place in the Premiership. A fifteenth-place finish the following season saw Royle resign towards the end of the campaign, to be temporarily replaced by club captain, Dave Watson. Howard Kendall was appointed Everton manager for the third time in 1997, but the appointment proved unsuccessful as Everton finished seventeenth in the Premiership; only avoiding relegation due to their superior goal difference over Bolton Wanderers. Former Rangers manager Walter Smith then took over from Kendall in the summer of 1998 but only managed three successive finishes in the bottom half of the table.

QUES: The rapid expansion of the Rus' to the south led to conflict and volatile relationships with the Khazars and other neighbors on the Pontic steppe. The Khazars dominated the Black Sea steppe during the 8th century, trading and frequently allying with the Byzantine Empire against Persians and Arabs. In the late 8th century, the collapse of the Gokturk Khaganate led the Magyars and the Pechenegs, Ugric and Turkic peoples from Central Asia, to migrate west into the steppe region, leading to military conflict, disruption of trade, and instability within the Khazar Khaganate. The Rus' and Slavs had earlier allied with the Khazars against Arab raids on the Caucasus, but they increasingly worked against them to secure control of the trade routes.
Who ruled the Black Sea steppe during the 800's?

In nature, uranium(VI) forms highly soluble carbonate complexes at alkaline pH. This leads to an increase in mobility and availability of uranium to groundwater and soil from nuclear wastes which leads to health hazards. However, it is difficult to precipitate uranium as phosphate in the presence of excess carbonate at alkaline pH. A Sphingomonas sp. strain BSAR-1 has been found to express a high activity alkaline phosphatase (PhoK) that has been applied for bioprecipitation of uranium as uranyl phosphate species from alkaline solutions. The precipitation ability was enhanced by overexpressing PhoK protein in E. coli.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What type of complexes does uranium(VI) not form in nature?
Ah, so.. unanswerable

Input: Read this: As of 2012[update] research continued in many fields. The university president, John Jenkins, described his hope that Notre Dame would become "one of the preeminent research institutions in the world" in his inaugural address. The university has many multi-disciplinary institutes devoted to research in varying fields, including the Medieval Institute, the Kellogg Institute for International Studies, the Kroc Institute for International Peace studies, and the Center for Social Concerns. Recent research includes work on family conflict and child development, genome mapping, the increasing trade deficit of the United States with China, studies in fluid mechanics, computational science and engineering, and marketing trends on the Internet. As of 2013, the university is home to the Notre Dame Global Adaptation Index which ranks countries annually based on how vulnerable they are to climate change and how prepared they are to adapt.
Question: What threat does the Global Adaptation Index study?

Output:
climate change
