Answer:
This is only asking for your opinion. My advice is to decide which side would be easier for you to write about. The teacher doesn't care what your true opinion is, only that you can write an essay.
First paragraph: Restate the question with your opinion
Pets should be (or should not be) allowed in all forms of public transportation. This is true because (reason 1), (reason 2), and (reason 3).
Second, third, fourth paragraphs: Explain your reasons.
The first reason pets should be (or should not be) allowed in all forms of public transportation is reason 1 from your introduction. Write a sentence explaining this reason. Then give a specific example.
Another reason pets should be (or should not be) allowed in all forms of public transportation is reason 2 from your introduction. Write a sentence explaining this reason. Then give a specific example.
A final reason pets should be (or should not be) allowed in all forms of public transportation is reason 3 from your introduction. Write a sentence explaining this reason. Then give a specific example.
(On one of those body paragraphs, you may want to introduce a counter-claim. This means an argument that someone who disagrees with you might use. For example: "Some people may say that pets should not be allowed on public transportation due to allergies, but...") Then you could give a reason why that opinion should not matter.
Final paragraph: Conclusion. Restate your introduction.
Pets should / should not be allowed on public transportation because reason 1, reason 2, and reason 3.
Explanation:
This is an outline for a very "standard" five paragraph essay. Is it the most creative form of writing? No. Will it get you a decent grade? Yes, probably. It would be a good idea for you to write this yourself since it is asking for your opinion, but you can just use this outline to do it quickly.
