C Correct answer
Explanation

The Vedic people, specifically during the Later Vedic period, discovered and began using iron, which they referred to as 'Shyama Ayas' or 'Krishna Ayas'. This allowed for clearing dense forests and expanding agriculture.

Multiple choice
  1. Alloy 1050

  2. Alloy 1060

  3. Alloy 1100

  4. Alloy 1199

  5. Alloy 2014

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Alloy 1050 contains 99.5% of aluminium by mass, alloy 1060 contains 99.6% aluminium by weight, alloy 1100 contains 99.0% aluminium by mass, alloy 1199 contains 99.9% of aluminium by weight and alloy 2014 contains 90.9% of aluminium by mass. Hence, alloy 1199 has the maximum percentage of aluminium by weight.
