Indus Valley Civilisation: 1. The Harappan script has not been deciphered so far. 2. Iron was widely used by the Harappans for making tools.

Statement 1 is correct: the Harappan seals bear a pictographic script that has not been deciphered. Statement 2 is wrong because the Harappans used copper, bronze, stone and no known iron; the iron age in India began roughly a thousand years later with the Vedic and megalithic cultures. The trap is the assumption that urban cultures used iron.
