The answer is B. Letter b and c.
Geospatial technology like GPS, GIS Google Earth, Lidar etc for example answer the question of where are both natural and artificial features located on the surface of the earth and what is their relationship ie of the natural features like segments of an esker for example or of mining of an esker to show the extent of the mining. This information is good for planning of say future mining, of constructing new buildings, pipelines, roads ie infrastructure. Geospatial technology can aid in the understanding of the landscape but cannot determine, for example where exactly an orebody exists, ie one that is buried under the ground, for this other means must be sought like exploration drilling, trenching etc.
The authors poem was extremely moving and shows such passion and emotion. He wants to demonstrate that we are not afraid of our fears, but instead our successes and that is causing us to be held back from the light we possess. The concept to grasp here is once you break out of your shell, the smiles and laughter you bring to the table, spread joy to others almost instantly. Overall the poem is extremely inspirational and causes feelings to make a difference in the world; Knowing YOU can make a difference in a humans life. Keeping yourself inadequate wasnt the point of the poem, but instead it was the point that nobody is perfect and no one will ever reach perfection in mans eyes. Keeping yourself inadequate is impossible, but the way you assess situations in your day to day life is what impacts you the most. The author addresses the term "light" several times throughout the poem as if it is a literal thing. However, the light he is speaking of is your own unique personality and traits that make you, you, and you should not be afraid to hold it back because it might just impact others.
