Plz, ! why is only 10% of australia’s land used for crop farming, even though over 55% of australia’s land is used for agriculture?

The correct answer is the following.

According to the Agriculture office of the government of Australia, the use of land in that country is used for different purposes.

45% of the Australian land is used for grazing natural vegetation. 7.8% for natural conservation. 15% are protected areas including indigenous uses. 1.5% for production forestry. 9.4% for grazing modified pastures. 3.59% for dryland cropping. 0.01% for dryland horticulture. 0.08% for irrigated pastures. 0.13% irrigated cropping. 0.06% for irrigated horticulture. 0.02% for intensive animal and plant production. 1.63% for water.

Australian land and climate allow the Aussies to have blessed crops with the actual usage of the land that provides food for its citizens and to export it as part of their trade efforts.  

i would say b. research typically uses a variety of sources
