Final answer:
Without knowing the specific density of the liquid in question, it is impossible to determine whether it is water, gasoline, or ethanol; thus, there is not enough information provided to make an identification.
Step-by-step explanation:
To determine whether the liquid is water, gasoline, or ethanol, we need to compare their respective densities. The density is a physical property that helps identify substances. Water has a density of 1.0 g/cm³, ethanol has a density of 0.79 g/cm³, and gasoline's density ranges from 0.70-0.77 g/cm³.
Since the liquid's density is not specified in the question, we do not have enough information to determine which substance it is. To identify the liquid accurately, the density of the liquid in question would need to be measured and compared to the known densities provided.
Without this, the answer is D) Not enough information to determine.
