Which of the following statements are true about agricultural practices in the Harappan society?

A) Most Harappan sites are located in wetlands, where irrigation was used for agriculture.
B) Archaeologists have also found evidence of a ploughed field at Kalibangan associated with Late Harappan levels.
C) The prevalence of agriculture is indicated by finds of grain.
D) It is difficult to reconstruct actual agricultural practices of Harappan society.
E) Archaeologists extrapolate from representations of bulls on seals and terracotta sculptures that oxen were used for ploughing.

Choose the correct answer from the given options:

C, D and E

The correct answer is Option 4 - C, D and E

The statements that are true about agricultural practices in the Harappan society are:

C) The prevalence of agriculture is indicated by finds of grain.
D) It is difficult to reconstruct actual agricultural practices of Harappan society.
E) Archaeologists extrapolate from representations of bulls on seals and terracotta sculptures that oxen were used for ploughing.

Agriculture in the Harappan society:

While the prevalence of agriculture is indicated by finds of grain (STATEMENT C) , it is more difficult to reconstruct actual agricultural practices (STATEMENT D). Were seeds broadcast (scattered) on ploughed lands? Representations on seals and terracotta sculpture indicate that the bull was known, and archaeologists extrapolate from this that oxen were used for ploughing (STATEMENT E). Moreover, terracotta models of the plough have been found at sites in Cholistan and at Banawali (Haryana). Archaeologists have also found evidence of a ploughed field at Kalibangan (Rajasthan), associated with Early Harappan levels (correct version of statement B). The field had two sets of furrows at right angles to each other, suggesting that two different crops were grown together. Archaeologists have also tried to identify the tools used for harvesting. Did the Harappans use stone blades set in wooden handles or did they use metal tools?

Most Harappan sites are located in semi-arid lands, where irrigation was probably required for agriculture (correct version of statement A). Traces of canals have been found at the Harappan site of Shortughai in Afghanistan, but not in Punjab or Sind. It is possible that ancient canals silted up long ago. It is also likely that water drawn from wells was used for irrigation. Besides, water reservoirs found in Dholavira (Gujarat) may have been used to store water for agriculture.

The incorrect statements with corrections are:

STATEMENT A) Most Harappan sites are located in SEMI-ARID LANDS, not wetlands, where irrigation was probably used for agriculture.
STATEMENT B) Archaeologists have also found evidence of a ploughed field at Kalibangan associated with EARLY Harappan levels, not Late Harappan levels.
