Question

Select the correct answer. Which statement would best conclude the following passage? Earth Hour is an annual event when people around the world turn off electrical lights to raise awareness about climate change. This voluntary act helps to reduce a significant amount of light pollution. Light pollution has harmful effects on both the environment and our body. Conducting Earth Hour regularly would gradually make the world a safer place to live in. It is merely a matter of an hour and not something that would cause too much of an inconvenience. A. Earth Hour originated in Australia, and it’s observed in the last week of March every year. B. Thus, Earth Hour should become a daily or monthly event rather than an annual event. C. Thus, Earth Hour is a necessary step against climate change and every person must join in. D. Climate change and global warming are two of the most serious problems we face today.

Answer 1

C. Thus, Earth Hour is a necessary step against climate change and every person must join in.

Step-by-step explanation:

Option C is the main idea of the passage, so it would be best to conclude the passage with this statement.

Option A is incorrect because this is introduction to Earth Hour and not a conclusion.

Option B is incorrect because nowhere in the passage the author gives such a suggestion. He/she just suggests it should be regularly observed as it does not cause much inconvenience, however if it is observed daily or monthly, it may cause inconvenience. Reaching such a surprise conclusion would not be good, because the author has not presented any arguments in support of this suggestion.

Option D is incorrect because this is not precisely the topic of the passage. The topic is Earth Hour and not global warming or climate change.
