Answer 1

Based on the above, Claim C is supported by the data observed in the chart.

The chart shows that meat production requires more land than agriculture to produce 100 grams of protein. For example, lamb and mutton require 184.8 square meters of land, while beef requires 163.6 square meters of land. In contrast, grains require only 4.6 square meters of land, and nuts require 7.9 square meters of land.

Therefore, This means that meat production is less efficient than agriculture per square meter. In other words, it takes more land to produce 100 grams of protein from meat than from agriculture.
