ample practices varied across time and place. The truth is that we about what preliterate societies knew or believed. But they left behind *. evidence of their attention to the movements of the Sun and the phases of the Moon. And we can be sure that whatever questions they asked of the heavens were very different from those that motivate space exploration today. (A) rotic othe In reality, the difference between ancient and modern knowledge systems is more qualitative than quantitative; it is not about how much is known, but about what questions are important and about the acceptable ways of asking and answering those questions. And while we may not easily be able to slip between our modern worldview and those of others, we can nonetheless attempt to do so by asking not what ancient people knew about the world, but what their questions were when they looked at it. If we do this in the case of Mars, examining a few of the earliest known examples from around the world, we can see how sky knowledge was considered important to the functioning of the state whether it was *astrological knowledge in the service of good governance, or knowledge of bloodlines and relationships with the gods and other sky entities, which was used (B) - verdd

10 The energies of conquest were not merely more efficient technologies. The European settlers used technological advantages for personal benefit. They viewed the land as a source of commodities as raw material waiting for transformation. 心理学 Although the psychology of the settlers varied considerably, according to class, religion, and nation of origin, most of them shared a set of beliefs that led to APP まめよ植えよ 15 expansionism.
