Which of the following is the most appropriate title of the passage?
In disrupting ecosystems, light pollution poses a serious threat in particular to nocturnal wildlife, having negative impacts on plant and animal physiology. It can confuse the migratory patterns of animals, alter competitive interactions of animals, change predator-prey relations, and cause physiological harm. The rhythm of life is orchestrated by the natural diurnal patterns of light and dark; so disruption to these patterns impacts the ecological dynamics. With respect to adverse health effects, many species, especially humans, are dependent on natural body cycles called circadian rhythms and the production of melatonin, which are regulated by light and dark (e.g., day and night). If humans are exposed to light while sleeping, melatonin production can be suppressed. This can lead to sleep disorders and other health problems such as increased headaches, worker fatigue, medically defined stress, some forms of obesity due to lack of sleep and increased anxiety. And ties are being found to a couple of types of cancer. There are also effects of glare on aging eyes. Health effects are not only due to over-illumination or excessive exposure of light over time, but also improper spectral composition of light (e.g., certain colors of light). With respect to energy wastage, lighting is responsible for at least one-fourth of all electricity consumption worldwide. Over illumination can constitute energy wastage, especially upward directed lighting at night. Energy wastage is also a waste in cost and carbon footprint.

How to Reduce Light Pollution for Better Ecosystem

Light Pollution Rising Rapidly on a Global Scale

Various Diurnal Patterns of Light and Dark

Importance of Light to Human Health

Inimical Effects of Light Pollution

가장 알맞은 제목은 “Inimical Effects of Light Pollution”(빛 공해의 해로운 영향)이다.
지문은 빛 공해의 폐해를 “disrupting ecosystems”(생태계 교란), “adverse health effects”(건강 악영향), “energy wastage”(에너지 낭비)의 세 측면으로 나누어 설명한다. “inimical”은 “해로운”이라는 뜻이다.
“How to Reduce Light Pollution for Better Ecosystem”은 감축 방법을 내세우지만 지문에 방법은 나오지 않는다.
“Light Pollution Rising Rapidly on a Global Scale”은 빛 공해의 증가 추세를 말하는데 지문이 다룬 내용이 아니다.
“Various Diurnal Patterns of Light and Dark”는 생태계 교란을 설명하려고 잠깐 언급된 소재일 뿐이다.
“Importance of Light to Human Health”는 빛의 유익함을 뜻해 방향이 반대이고, 생태계·에너지 측면도 빠진다.
