Final answer:
The text 'searching for the source of life' uniquely offers information about scientific experiments linked to various hypotheses on the origin of life on Earth, highlighted through supporting scientific evidence and scientific methodsoption. A is the correct answer.
Step-by-step explanation:
In comparing the texts, we find that only "searching for the source of life" provides information about scientific experiments. This is because the text refers to various hypotheses regarding the natural origin of life on Earth supported by scientific evidence. These hypotheses are tested through scientific methods, which include controlled experiments and data evaluation to answer specific scientific questions about life's origins.
Texts that detail mythical creatures or historical events may not provide empirical evidence or scientific explanations; hence, those options do not fit the context provided. Artistic expressions, while valuable in their own right, are not centered around scientific experimentation either.
Therefore, the correct option in the final answer is (a) Scientific experiments, as it is the only option that aligns with the scientific inquiry and data evaluation aspects mentioned within the text concerning life's origins on Earth.
