Marking points

  1. 1 Gives a first valid conclusion supported by Figure 1.
  2. 2 Gives a second, distinct valid conclusion supported by Figure 1.

Full-mark answer

The mass of copper produced increased from 1900 to 2010. The increase was slight before about 1930 but rapid after about 1930.

Why this answer loses marks
