Q. A chameleon is looking for prey. Let positive numbers represent the elevation of prey above the chameleon and negative numbers represent the elevation of prey below the chameleon. \newlineThe chameleon spots a fly at 4m4\,\text{m} and a grasshopper at 6m-6\,\text{m}. \newlineWhat does an elevation of 0m0\,\text{m} represent in this situation?\newline Choose 11 answer: \newline(A) The elevation of the fly \newline(B) The elevation of the chameleon \newline(C) The elevation of the grasshopper
  1. Understand Problem Context: Understand the context of the problem.\newlineIn this scenario, positive numbers represent the elevation of prey above the chameleon, and negative numbers represent the elevation of prey below the chameleon. The fly is at +4m+4\,\text{m}, which means it is above the chameleon, and the grasshopper is at 6m-6\,\text{m}, which means it is below the chameleon.
  2. Determine 0m0\,\text{m} Elevation: Determine what 0m0\,\text{m} elevation represents.\newlineSince positive numbers are above the chameleon and negative numbers are below, 0m0\,\text{m} would logically represent the elevation of the chameleon itself, as it is neither above nor below.
  3. Match Elevation with Answer: Match the elevation of 0m0\text{m} with the correct answer choice.\newlineThe elevation of the fly is +4m+4\text{m}, and the elevation of the grasshopper is 6m-6\text{m}. Therefore, neither of these is at 0m0\text{m}. The only logical conclusion is that 0m0\text{m} represents the elevation of the chameleon.
