Q1. CAZRI institute is mainly involved in research on __________.
A Mining of minerals
B Sustainable farming systems in arid ecosystem Correct
C Animal husbandry in desert
D Land reforms
Explanation
CAZRI, the Central Arid Zone Research Institute at Jodhpur, works mainly on agriculture and natural-resource management for arid regions. Its core research includes sustainable farming systems, dryland crops, soil and water conservation, and livelihood support in desert ecosystems. Mining of minerals belongs to mineral and geology agencies, not CAZRI's main mandate. Animal husbandry in the desert can be related to arid livelihoods, but it is narrower than the institute's central farming-systems focus. Land reforms are a policy and administration subject, not its research focus.
