Just right.

A topic sentence states the main question that your essay will attempt to answer. It should summarize the main idea of the essay but without being too broad. This topic question is just right because it has all the elements required from a topic idea. The sentence clearly states what the main issue to be discussed is (recycling is important) without giving too many unecessary details. The question is also simple enough that it can be answered in a satisfactory way in an essay.

the words "interested" and "interesting" are in the same word group as they are based in the noun "interest". however, their meanings are very different.
