Read the paragraph.

forests are more than just a pretty addition to the landscape. forests the environment by soaking up carbon dioxide, conserving soil, and preventing flooding. forests people by providing a place to live and by providing jobs. over 300 million people worldwide live in forests, and over 1.6 billion people depend on forests for their jobs.

which best revises a sentence from the paragraph by adding an appropriate transition?

similarly, forests are more than just a pretty addition to the landscape.
for example, forests the environment by soaking up carbon dioxide, conserving soil, and preventing flooding.
however, forests people by providing a place to live and by providing jobs.
to summarize, over 300 million people worldwide live in forests, and over 1.6 billion people depend on forests for their jobs.

For example, forests help the environment by soaking up carbon dioxide, conserving soil, and preventing flooding.

This is the best answer. Let's first go through why the other answers do not work. We don't have enough information to use similarly in the first sentence. We don't know what information comes before this first paragraph that this sentence would be similar to. However is a transition that introduces a contradiction. None of the information in this paragraph contradicts anything or changes to a different perspective. The last option is also not correct because the last sentence of the paragraph doesn't actually summarize the information in the paragraph.  The second option is the best because the sentence is actually an example of how the forests "are more than just a pretty addition to the landscape."

B. For example, forests help the environment by soaking up carbon dioxide, conserving soil, and preventing flooding

Explanation:

it's like watching a fable, it's not really about the animals but rather it has a meaning that is understood by us and that is implicit, not explicitly said. implicit ideas are common and are used in almost all works of art, from writing to painting to sculpting.
