Student A:The river loses nearly two-thirds of its potential flow in the Inner Delta between Segou and Timbuktu to seepage and evaporation. All the water from the Bani River, which flows into the Delta at Mopti, does not compensate for the' losses'. The average' loss' is estimated at 31 km / year, but varies considerably between years. The river is then joined by various tributaries, but also loses more water to evaporation. The quantity of water entering Nigeria measured in Yola was estimated at 25 km / year before the 1980s and at 13.5 km / year during the 1980s. The most important tributary of the Niger in Nigeria is the Benue River which merges with the river at Lokoja in Nigeria. The total volume of tributaries in Nigeria is six times higher than the inflow into Nigeria, with a flow near the mouth of the river standing at 177.0 km / year before the 1980s and 147.3 km / year during the 1980s.

Student B:OK... The important part for answering this question is: The most important tributary of the Niger in Nigeria is the Benue River which merges with the river at Lokoja in Nigeria.

Problem:The break-up of the centralised Mughal empire by 1750, led to the creation of numerous semi-independent kingdoms (all provinces of the former Mughal empire). Nawab Siraj ud-Daulah was defeated by the British forces of Sir Robert Clive in the Battle of Plassey in 1757. Thereafter the Nawab of Bengal became a "puppet ruler" depending on military support from British East India company to secure their throne. Siraj-ud-Daulah was replaced by Mir Jaffer. He was personally led to the throne by Robert Clive, after triumph of the British in the battle. He briefly tried to re-assert his power by allying with the Dutch, but this plan was ended by the Battle of Chinsurah. After the defeat at Battle of Buxar and grant of the Diwani (revenue collection) of Bengal by the then Mughal Emperor Shah Alam II, to the British East India Company in August 1765 and the appointment of Warren Hastings by the East India Company as their first Governor General of Bengal in 1773, the Nawabs authority became restricted. By 1773, British East India company asserted much authority and formed the Bengal Presidency over areas ruled by the Nawabs i.e. the Bengal subah, along with some other regions and abolished the system of Dual Government. In 1793 (during Nawab Mubarak ud-Daulah's reign), the Nizamat (military power, civil and criminal justice) was abolished, British East India company thus annexed this former Mughal province as part of their empire and took complete control of the region, and the Nawabs of Bengal became mere pensioners of the British East India Company. All the Diwan offices except the Diwan Ton were also abolished.
