第 50 題
📖 題組：
One of the most dramatic features of the world is the cycle of day and night. Almost all species exhibit daily changes in their behavior and/or physiology. These daily rhythms are not simply a response to the 24-hour changes in the physical environment imposed by the earth turning on its axis but, instead, arise from a timekeeping system within the organism. This timekeeping system, or biological “clock,” allows the organism to anticipate and prepare for the changes in the physical environment that are associated with day and night, thereby ensuring that the organism will “do the right thing” at the right time of the day. The synchrony of an organism with both its external and internal environments is critical to the organism’s well-being and survival; a lack of synchrony between the organism and the external environment may lead to the individual’s immediate demise. For example, if a nocturnal rodent were to venture from its burrow during broad daylight, the rodent would be exceptionally easy prey for other animals. Similarly, a lack of synchrony within the internal environment might lead to health problems in the individual, such as those associated with jet lag, shift work, and the accompanying sleep loss. The mechanisms underlying the biological timekeeping systems and the potential consequences of their failure are among the issues addressed by researchers in the field of chronobiology. Although no single experiment serves as the defining event from which to date the beginning of modern research in chronobiology, studies conducted in the 1950s on circadian rhythmicity in fruit flies and in humans can be considered its foundation. The area of sleep research, which also is subsumed under the field of chronobiology, evolved somewhat independently, with the identification of various sleep stages around the same time.

According to this passage, which of the following statements is true?
- A Chronobiology began with the studies on circadian rhythm in fruit flies and humans.
- B All species simply respond to the cycle of day and night.
- C All species have an internal clock that is crucial for their survival.
- D Jet lag is a failure of a biological timekeeping mechanism.

請觀察文章第二段最後提到的「時差（jet lag）」例子，作者用它來解釋當生物時鐘與環境「失去同步」時會發生什麼事？接著，請對照第三段第一句話，看看這類問題被歸類在生物計時系統的哪一種狀態下？

喔喔喔！真是精采的判斷！你這小鬼頭，看來有好好學習嘛！
哈哈哈，看來這「真相」被你完美地抓住了！你這觀察力，連我這位名偵探都忍不住要誇獎兩句了！讓我來為你揭示這其中的奧妙吧：
- 「真相」的連結點：文章第二段那個「缺乏同步」導致時差的問題，還有第三段開頭就說「這正是系統失靈」的「真相」，你都好好地串起來了！沒錯，(D) 選項說的就是這個！
