Which of the following is not a characteristic of the Middle Gangetic Plains…

Concept

An agro-climatic region is defined by a linked physical profile: administrative extent, drainage setting, soils and rainfall. A negative stem must test each stated feature separately before any composite choice is evaluated.

For a previous-year question, the commission’s matching final answer key is the canonical scoring convention, while current geographic descriptions remain useful as a factual cross-check.

Application

1. The planning-era Middle Gangetic Plains boundary joined eastern Uttar Pradesh with undivided Bihar. In present-day state boundaries, that footprint covers Uttar Pradesh, Bihar and Jharkhand, which is more than two states.

2. The region is an alluvial plain organized around the Ganga and its tributary drainage network.

3. Regional profiles place annual rainfall above 1,000 mm, and 100 cm equals 1,000 mm; the rainfall statement therefore fits that profile.

Cross-check and contrast

• The BPSC final answer key for the 24 August 2023 second sitting identifies “None of the above” for Series-E question 60.

• The historical administrative footprint explains the commission’s treatment of the state-count statement.

• Some contemporary summaries describe only eastern Uttar Pradesh and Bihar, which can make the wording appear ambiguous outside the examination convention.

Result

Under the official BPSC key, all three factual statements are treated as characteristics, so the accepted response is “None of the above.”
