Read the passage. the problem is too many used tires are piling up in city lots. one positive, alternative use of these tires is to shred them into small pieces and use them to make rubberized asphalt on highway paving projects. another way to reduce the number of discarded tires is to retread them so that they can continue to be used on cars. there is an obvious logic in using tires to make roads. plus, rubberized asphalt creates a better car ride. more states should look into this option. what type of problem-and-solution organization does this paragraph use? problem/cause/solution problem/solution problem/solution/solution/recommend ation

I think it could mabey be number 3.

number 3 i need twenty characters  so

"freedom of speech, freedom of worship, freedom from want, and freedom from fear.

quite an interesting way to teach topic sentences, because the answer to this question is the best definition of a topic sentence that one can present, it is as if answering the questions taught you how to do it, this is some real teaching, it is terribly well-done.

the topic sentence in this paragraph is:

topic sentences writers stay on track and keep a paragraph from becoming an aimless collection of sentences about an idea.

which incidentally tells you what a topic sentence should be.
