In early times, the privilege of papal election was not reserved to the cardinals, and for centuries the person elected was customarily a Roman priest and never a bishop from elsewhere. To preserve apostolic succession the rite of consecrating him a bishop had to be performed by someone who was already a bishop. The rule remains that, if the person elected Pope is not yet a bishop, he is consecrated by the Dean of the College of Cardinals, the Cardinal Bishop of Ostia.
Why did the ceromony of consecrating a bishop have to be preformed by someone who was already a bishop?
A: To preserve apostolic succession

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)."
Which measures the potential development, the HDI or the IHDI?
A: the HDI

Red is the international color of stop signs and stop lights on highways and intersections. It was standarized as the international color at the Vienna Convention on Road Signs and Signals of 1968. It was chosen partly because red is the brightest color in daytime (next to orange), though it is less visible at twilight, when green is the most visible color. Red also stands out more clearly against a cool natural backdrop of blue sky, green trees or gray buildings. But it was mostly chosen as the color for stoplights and stop signs because of its universal association with danger and warning.
