It seems that the correct answer is <em>a) Passage 1 explains his central idea</em>, while passage 2 supports it. In Of the Wisdom of the Ancients, Francis Bacon tries to give the 32-Greco-Roman-legends a new interpretation. In fact, in passage one he established the central idea of the text:
• “<em>the natural motion of the atom; which is indeed the original and unique force that constitutes and fashions all things out of matter.</em>”
With these lines, he states that the center of everything is the atom; it is what constitutes and defines the identity of thing/human beings.
While in passage 2 he reinforces this idea by mentioning:
• “<em>whereas the primary seeds of things, or atoms, are minute and remain in perpetual infancy.</em>”
Therefore, Bacon comments that although this character gained more attributes as he becomes older, his essence (seed/atom) will last forever.
