Sagot :
The word "It" in paragraph 2 refers to the term "recycling"
This text talks about good practices that should be followed at home to avoid polluting the environment, among which reuse, reduce and recycle, and not wastewater.
In the second paragraph, the author talks about recycling, as a practice that allows reusing some products such as paper, and others.
In this paragraph (second paragraph) the author uses the word "it" to refer to recycling as an antecedent, this can be known because this is the main topic of this paragraph and in the first sentence he uses it as the main subject "Recycle can also reduce the number of trees cut down to produce paper products" and then refers to this same activity with the subject "it".
Additionally, the options "the number", "effort" and "cutting down" are not the correct answer because they are not specific concepts discussed in paragraph 2.
