Question

what is the best example of how gps contributes to a practical field?
it helps shipping companies track precise locations of cargo
it helps meteorologists determine the impact of global warming
it helps agricultural workers manage crop and harvest data
it helps programmers combine and manipulate datasets.
it helps geologists gather data on layers of sedimentary rock.

Explanation:

GPS (Global Positioning System) is primarily used for tracking precise locations. Shipping companies need to know the exact whereabouts of their cargo for logistics and security. Meteorologists use other tools (like satellites for weather patterns, not GPS for global warming impact directly). Agricultural workers use other tech for crop data (like sensors). Programmers use software tools for datasets. Geologists use geological sampling etc. for sedimentary rock data. GPS's core function aligns with location - tracking which is crucial for shipping cargo.

Answer:

It helps shipping companies track precise locations of cargo.
