Step-by-step explanation:
A statement is a sentence that can be evaluated as either true or false. In the given list, sentences that express a fact, opinion, or some form of information that can be verified are considered statements.
For example, "Force equals mass times acceleration" is a scientific statement expressing Newton's second law of motion, which is either true or false based on the principles of physics. Similarly, "Today is Tuesday" is a factual statement that is true or false depending on the actual day.
In contrast, questions, suggestions, commands, and conditional statements are not considered statements. For instance, "Which way do I turn to get to your house?" is a question, and "I propose a toast" is a suggestion, neither of which can be classified as a statement.
In summary, the sentences identified as statements convey factual or opinion-based information that can be evaluated for truthfulness, distinguishing them from other types of sentence structures present in the given list.
