read the following introductory paragraph, which is missing a hook: light from the sun hits earth and warms the planet. the warm soil and water then release some of that heat back into the air. some of it escapes into space, and some of it is caught and held by gases in the atmosphere. this heat trapping process is called the greenhouse effect, after what the windows in a greenhouse or a car do with solar radiation - they let the light move in and out, but trap a lot of the heat inside. which option below makes the most effective hook? there is now overwhelming scientific consensus that climate change is happening - the average temperature of the earth’s surface increased by about 1.4°f over the 20th century, with two thirds of it happening since 1980. i remember playing in snowdrifts higher than my head when i was a kid. my kids have never had that joy. it doesn’t snow much here anymore. because of global warming, it probably never will. for billions of years, the greenhouse effect was the best friend to life on earth. without it, the average global air temperature would be barely above 0°f. this is how it works. it is ironic that the greenhouse effect is named after a place where plants grow, because it is going to destroy life on earth.

Answer

Brief Explanations:

A hook should grab the reader's attention and introduce the topic. The third option starts with a long - term perspective on the greenhouse effect's importance to life on Earth and then leads into how it works, which smoothly connects to the following text about the greenhouse effect. The first option is more about climate change data rather than directly hooking into the greenhouse effect. The second option is a personal anecdote which may be less relevant to the scientific explanation of the greenhouse effect. The fourth option is an extreme and somewhat inaccurate statement that doesn't set up the scientific explanation well.

Answer:

For billions of years, the greenhouse effect was the best friend to life on Earth. Without it, the average global air temperature would be barely above 0°F. This is how it works.
