During the last interglacial period, the Red Sea coast of Eritrea was occupied by early anatomically modern humans. It is believed that the area was on the route out of Africa that some scholars suggest was used by early humans to colonize the rest of the Old World. In 1999, the Eritrean Research Project Team composed of Eritrean, Canadian, American, Dutch and French scientists discovered a Paleolithic site with stone and obsidian tools dated to over 125,000 years old near the Bay of Zula south of Massawa, along the Red Sea littoral. The tools are believed to have been used by early humans to harvest marine resources like clams and oysters.
Where did the Research Project Team find the obsidian tools?

The Directorate of Operations is responsible for collecting foreign intelligence, mainly from clandestine HUMINT sources, and covert action. The name reflects its role as the coordinator of human intelligence activities among other elements of the wider U.S. intelligence community with their own HUMINT operations. This Directorate was created in an attempt to end years of rivalry over influence, philosophy and budget between the United States Department of Defense (DOD) and the CIA. In spite of this, the Department of Defense recently organized its own global clandestine intelligence service, the Defense Clandestine Service (DCS), under the Defense Intelligence Agency (DIA).
What intelligence service did the Department of Defense recently create?
A: the Defense Clandestine Service

The metro leaves the Rodoviaria (bus station) and goes south, avoiding most of the political and tourist areas. The main purpose of the metro is to serve cities, such as Samambaia, Taguatinga and Ceilandia, as well as Guara and Aguas Claras. The satellite cities served are more populated in total than the Plano Piloto itself (the census of 2000 indicated that Ceilandia had 344,039 inhabitants, Taguatinga had 243,575, whereas the Plano Piloto had approximately 400,000 inhabitants), and most residents of the satellite cities depend on public transportation.
What do most residents of the Rodoviaria depend on?
A: unanswerable

Romila Thapar notes that the division into Hindu-Muslim-British periods of Indian history gives too much weight to "ruling dynasties and foreign invasions", neglecting the social-economic history which often showed a strong continuity.

What type of history period is often neglected in Indian histories?
