(a) Study Fig. 5.1 (Insert), which is a photograph of an area where subsistence farming takes place. [Figure 5.1 (Insert) is a photograph depicting an area of subsistence farming. It likely shows small plots of cultivated land, possibly with a mix of crops and some livestock, surrounded by natural vegetation or trees. Evidence of manual labor or simple tools might be visible.] (b) Study Fig. 5.2, which is a graph showing information about the world production of wheat and rice between 1980 and 2013. [Figure 5.2 is a line graph with 'year' (1980-2013) on the x-axis and 'production (millions of tonnes)' (0-1000) on the y-axis. Two lines are plotted: 'wheat' and 'rice'. The wheat line shows production generally increasing from around 425 million tonnes in 1980 to 660 million tonnes in 2013, with fluctuations. The rice line shows production generally increasing from around 260 million tonnes in 1980 to 465 million tonnes in 2013, also with fluctuations.]
