- What are the evidences available regarding crops and domesticated animals of Indus Valley Civilization? What are the views of the scholars regarding Indus script? (Answer in 250 words)
Introduction
Harappan subsistence is now well documented by archaeobotany and faunal analysis; the script, by contrast, remains undeciphered and even its status as writing is disputed.

Body
1. The crop evidence: recovered by flotation, seed impressions on pottery and mud brick, and phytoliths. Wheat and barley were the rabi staples at Mehrgarh, Harappa and Kalibangan; the Gujarat and eastern sites add kharif millets — bajra, jowar, ragi and Setaria — with rice at Lothal and Rangpur. Pulses include lentil, chickpea, field pea and green and black gram; sesame, linseed and mustard supplied oil, and Mehrgarh has the world's earliest cotton. The ploughed field at Kalibangan, with furrows crossing at right angles, shows two crops grown together.
2. The animal evidence: the humped zebu dominates both the bone assemblages and the seals; water buffalo, sheep, goat, pig, dog, fowl and donkey are securely domestic. The elephant was probably tamed. The horse is contested — the Surkotada bones identified by Bokonyi were disputed by Meadow and Patel, and no chariot is attested.
3. The script itself: roughly four hundred distinct signs, written right to left, in inscriptions averaging about five signs and rarely exceeding twenty. There is no bilingual, no long text and no securely known language, which is why decipherment fails.
4. The competing positions: Parpola and Mahadevan argue for a Dravidian language, resting on the fish sign and the northern relic Brahui. Others propose Indo-Aryan or a Munda substrate. Farmer, Sproat and Witzel argued in 2004 that the sequences are non-linguistic symbols, which Rao's entropy analysis of 2009 contested.

Conclusion
The subsistence base is settled: mixed cereal farming with cattle at its centre. The script is not, and the prize now offered for its decipherment measures how open the question remains.
