Problem: Human Development Index:

The 2010 Human Development Report introduced an Inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development (accounting for inequality)," and "the HDI can be viewed as an index of 'potential' human development (or the maximum IHDI that could be achieved if there were no inequality)."

What does IHDI2 stand for?

Problem: Crimean War:

1855: Georgian coast: Omar Pasha, the Turkish commander at Crimea had long wanted to land in Georgia, but the western powers vetoed it. When they relented in August most of the campaigning season was lost. In September 8000 Turks landed at Batum, but the main concentration was at Sukhum Kale. This required a 100-mile march south through a country with poor roads. The Russians planned to hold the line of the Ingur River which separates Abkhazia from Georgia proper. Omar crossed the Ingur on 7 November and then wasted a great deal of time, the Russians doing little. By 2 December he had reached the Tskhenis-dzqali, the rainy season had started, his camps were submerged in mud and there was no bread. Learning of the fall of Kars he withdrew to the Ingur. The Russians did nothing and he evacuated to Batum in February of the following year.

In September of 1855, how many Turks could be found at Batum?
---
A: 8000

Problem: Dutch language:

The Germanic languages are traditionally divided into three groups: West, East and North Germanic. They remained mutually intelligible throughout the Migration Period. Dutch is together with English and German part of the West Germanic group, that is characterized by a number of phonological and morphological innovations not found in North and East Germanic. The West Germanic varieties of the time are generally split into three dialect groups: Ingvaeonic (North Sea Germanic), Istvaeonic (Weser-Rhine Germanic) and Irminonic (Elbe Germanic). It appears that the Frankish tribes fit primarily into the Istvaeonic dialect group with certain Ingvaeonic influences towards the northwest, still seen in modern Dutch.

In what historical period did the different types of Germanic languages stop being collectively understood?
---
A:
the Migration Period
