Electric light is transforming our world. Around 80% of the global population now lives in places where night skies are polluted with artificial light. A third of humanity can no longer see the Milky Way. But light at night has deeper effects. In humans, nocturnal* light pollution has been linked to sleep disorders, depression, obesity and even some types of cancer. Studies have shown that nocturnal animals modify their 変更する behavior even with slight changes in night-time light levels. Dung beetles* become でさえ disoriented when navigating landscapes if light pollution prevents them from seeing the 方向感覚を失わせる。 移動する Spes Ing & PR stars. Light can also change how species interact with each other.

In the United States, safety regulations are ( 30 ). Although some vehicles have become larger and their shape has changed, laws have not changed to reflect the increased danger they pose to pedestrians. Critics say that regulating only the safety of vehicle occupants is irresponsible, and that pedestrian deaths have increased even though there are simple measures that could be taken to help prevent them.

Flow happens at a point of balance between boredom and frustration. (3) On the other hand, if the challenge is too high relative to the individual's skill level, frustration becomes likely. The flow state sets in when the challenge level of the activity meets the skill level of the person. In this sense, flow is related to what we call "fun." () For example, climbers will move on to ascend more demanding rock formations, and chess players will seek to play against more skillful opponents. ✓ (A) One of its defining characteristics is the loss of the sense of self and time because absorption in the task at hand is so complete. (B) Flow, as famously investigated by Mihaly Csikszentmihalyi, is a mental state characterized by deep absorption during challenging activities. (C) Moreover, as our skills improve in the activity, we seek to increase the challenge in order to keep experiencing flow. (D) If an activity provides a level of challenge that is too low relative to the skill level of the person, it becomes boring,

資料解釈の問題なのですが、選択肢4の赤線が引かれている部分についてです。7878を8000でなく、7000にして計算すると誤差が広がりませんか？なぜ7000にするのでしょうか？

肢1 A国の総数は 78,448 で、 これの30%は 23,000 以上になります。 しかし、 固形は 22,596 ですから､ 総数の30%を上回ることはありません。 肢2 肢1の計算より、A国の液体も総数の30% に 満たないのがわかります。 一方、B国の総数 17,868 の30%は 6,000 にも及びませんので、液体の占める 割合は30%を上回ります。 よって、B国のほうが高いとわかり、本肢は妥当で すね｡ 肢3 総数はA国がB国の4倍以上あるのに、両国の 電力はそれほど大きく変わりませんね。 B国のほうが 割合は高いとわかります。 肢4 B国の液体は 7,878 で、 これの80% は 5,600 以上になります。 ガスは5,467 ですから、 液体の80% 4 LEVEL 1 ちょっと補足 78,000 × 0.3= 23,400だか ら。 78,448 の30% はもっと あるよね。 もちろん、 22,596 78,448 を概数計算してもいいけど、割 り算よりかけ算のほうがちょっ と楽でしょ!? 7,000 × 0.8 = 5,600 だからね。
