There is not one correct answer for these exercises because there will be more than one plausible generalisation that the arguer could be relying on. But here are some suggested answers.

1. If nobody has managed to build something even when people have tried, no one will ever build it.

2. If you enjoy doing something then, even if other people say you shouldn’t do it, you should do it.

3. If something is not working, even though it has just been looked at by a professional, you should repair it yourself this time.

4. If you can easily use something to kill or seriously injure someone, civilians shouldn't be allowed to keep that thing at home.

5. If most people in group A are also in group B, most people in group B are also in group A.

6. If it won't take you long to do something, and doing it will help someone else, you should probably do that thing.

7. If an animal isn't a bird or an insect, then it can't fly.

8. The majority of the best players of a sport come from the country in which that sport was invented.

9. If you like food A and you like food B, then you would probably like a combination of foods A and B.

10. If most of the people who get something illegally could not afford to buy that thing legally, then getting that thing illegally is not immoral.
