"It's a Fact, Jack!" worksheet from Magic Tree House, designed to help students distinguish between facts and opinions related to the Titanic.

Problem Overview:

The task involves identifying whether each statement is a fact or an opinion. A fact is a statement that can be proven true or false based on evidence, while an opinion is a subjective belief or judgment that cannot be definitively proven.

Solution Approach:

1. Definition of Fact: A fact is an objective truth that can be verified through evidence, research, or observation.
2. Definition of Opinion: An opinion is a subjective statement that reflects personal beliefs, feelings, or judgments and cannot be universally proven.

We will analyze each statement to determine whether it is a fact or an opinion.
