question:
Around 2.5 million years ago (ending 11,600 years ago) was the geological period of the Ice Ages. Since approximately 600,000 years ago, six major Ice Ages have occurred, in which sea level dropped 120 m (390 ft) and much of the continental margins became exposed. In the Early Pleistocene, the Rhine followed a course to the northwest, through the present North Sea. During the so-called Anglian glaciation (~450,000 yr BP, marine oxygen isotope stage 12), the northern part of the present North Sea was blocked by the ice and a large lake developed, that overflowed through the English Channel. This caused the Rhine's course to be diverted through the English Channel. Since then, during glacial times, the river mouth was located offshore of Brest, France and rivers, like the Thames and the Seine, became tributaries to the Rhine. During interglacials, when sea level rose to approximately the present level, the Rhine built deltas, in what is now the Netherlands.
answer:
What period was 2.5 million years ago?


question:
In 1998, UNICEF reported that Ivory Coast farmers used enslaved children – many from surrounding countries. In late 2000 a BBC documentary reported the use of enslaved children in the production of cocoa—the main ingredient in chocolate— in West Africa. Other media followed by reporting widespread child slavery and child trafficking in the production of cocoa. In 2001, the US State Department estimated there were 15,000 child slaves cocoa, cotton and coffee farms in the Ivory Coast, and the Chocolate Manufacturers Association acknowledged that child slavery is used in the cocoa harvest.[not in citation given][better source needed]
answer:
Who reported Ivory Coast farmers usage of child labour?


question:
Florida is among the three states with the most severe felony disenfranchisement laws. Florida requires felons to have completed sentencing, parole and/or probation, and then seven years later, to apply individually for restoration of voting privileges. As in other aspects of the criminal justice system, this law has disproportionate effects for minorities. As a result, according to Brent Staples, based on data from The Sentencing Project, the effect of Florida's law is such that in 2014 "[m]ore than one in ten Floridians – and nearly one in four African-American Floridians – are shut out of the polls because of felony convictions."
answer:

How severe are Florida disenfranchisement laws
