Question

instead of tossing your banana peel in the trash, you can turn it into a fertilizer to help other plants grow. in fact, you can put many plant - based food scraps and yard waste in a special bin where they can naturally compost, or break down. after a few weeks of mixing, your old waste will turn into fertilizer. that fertilizer can then be added to the soil to help your plants grow.
text 2
at least a quarter of the trash that is thrown away today consists of food scraps and yard waste. when these materials go to a landfill and break down, they release methane, a powerful greenhouse gas that harms the environment. to prevent this, people can put their food scraps and yard waste into a separate bin for composting. this process reduces the amount of trash that goes into landfills. as a result, fewer greenhouse gases are produced.
which sentence best combines the main, or central, ideas of both texts?
people who compost mainly do it to take care of the environment rather than to improve their gardens.
composting is good for the environment, and it also creates a fertilizer that helps plants grow.
composting is an easy way to create fertilizer, but it stops landfills from producing important gases.

Explanation:

• First, analyze Text 1: It focuses on composting food scraps/yard waste to make fertilizer for plants.
• Then, analyze Text 2: It focuses on composting to reduce landfill - related greenhouse gas emissions (good for the environment).
• Now, evaluate the options:
• Option 1: The first text also mentions using compost for gardens, so this option's "rather than to improve their gardens" is incorrect.
• Option 2: It combines the two ideas - composting is good for the environment (from Text 2) and creates fertilizer for plants (from Text 1).
• Option 3: Landfills produce harmful methane, not "important gases", so this option is incorrect.

Answer:

B. Composting is good for the environment, and it also creates a fertilizer that helps plants grow.
