找到答案的依據在于穩重這樣一句話：

The predator is searchingly aggressive, inner-directed, tuned by the nervous system and the adrenal hormones, but aware in a sense closer to human consciousness than, say, a hungry lizard’s instinctive snap at a passing beetle.

于是，正確答案為選項 (C) make a distinction between higher and lower levels of consciousness

其實，許多同學依然無法通過這句話與選項產生聯系，感覺找不到 a distinction，也找不到 higher and lower levels of consciousness。其實，我們首先把這句話簡化到核心： The predator is … aware in a sense closer to human consciousness than, say, a hungry lizard’s instinctive snap at a passing beetle，然后我們發現句子的核心是一個比較級。closer to … than …那既然是比較，那是不是 a distinction（差別/區分）就出來了？

接下來，我們看到比較的兩個主體：predator vs lizard。比較的方面是：與 human consciousness（人類意識作為高級意識）有多 close （靠近）。那么，很顯然，哪個closer to（更靠近于） human consciousness（人類意識）, 哪個就是higher levels of consciousness，對應的就是 lower levels of consciousness。
