In 1879 he created a successful incandescent light bulb. This was his hardest project – from 1877 to 1880, Edison and his assistants tried around 3000 experiments to perfect their light bulb design. By the end of 1880, Edison had produced a bulb that lasted 1500 hours. This discovery marked the beginning of commercially manufactured light bulbs and in 1880, Thomas Edison’s company, Edison Electric Light Company began marketing its new product.

Read the passage below and decide whether the statements are TRUE or FALSE?

Light pollution is the excessive, misdirected or invasive use of artificial outdoor lighting. Mismanaged lighting affects the environment, energy resources, wildlife, humans and astronomy research.

Light pollution is not a new phenomenon. Over the last 50 years, as countries became affluent and urbanized, demand for outdoor lighting increased and light pollution sprawled beyond the city limits and into suburban and rural areas. This form pollution is now prevalent in Asia, Europe, and North America, particularly in cities like Los Angeles, New York and Washington D.C. In 2008, National Geographic magazine named Chicago the most light-polluted city in the United States.

However, the most light-polluted spot in the world is Hong Kong, China. In March 2013, the University of Hong Kong named the city the most light polluted in the world. A study by the university found the night sky in Tsim Sha Tsui, an urban neighborhood in southern Kowloon, Hong Kong, to be 1,200 times brighter than a normal urban city sky. Luminous pollution of this magnitude is on the rise worldwide. In a 2010 article from the Ecology and Society Journal, Hölker and others stated the use of artificial lighting increases by 20% each year, depending on the region, and noted there is an urgent need for light pollution policies that surpass energy efficiency to include humans, animals and the environment.

Question : Light pollution sprawled beyond the city limits and into suburban and rural areas.”.

A. True

B. False
