1. Based on the examples in the table, how do opinions differ from facts?
baherus [9]

1. Opinions are not always right; facts are.

2. Theories are sometimes right, but sometimes they are either wrong or a little off; facts are on point and with the exact answer.

3.  A theory is a scientific explanation of a fact.

4. They all have a good amount of information; also they say approximately to let you know it's not the exact answer.

5. A law is more like a prediction of what will happen if the situation is given and it's shown by the mathematical equation; Theory describes what happens. (Happened).

6. This would try to go against my understanding but it won't happen because I know that theories don't become laws or vice-versa; theories remain theories and law remain laws.
