premise: Astana ( , ; Kazakh: Astana ] ) is the capital city of Kazakhstan. It is located on the banks of Ishim River in the north portion of Kazakhstan, within the Akmola Region, though administrated separately from the region as a city with special status. The 2017 census reported a population of 1,006,574 within the city limits, making it the second-largest city in Kazakhstan, behind Almaty.
hypothesis: There were two other cities that had a higher population compared to Astana in 2017.
reason: There was only one other city that had a higher population in 2017 so that makes the statement incorrect but I think the AI connected the word two with second and marked it as correct.
