<human>:  How can I differentiate between fact and opinion in the news?
<bot>: To differentiate between fact and opinion in the news, there are several considerations you should take into account. Look for statements that are reported as facts (e.g. “President Johnson signed the Clean Air Act in 1963”) and statements that are based on opinion (e.g. “The Clean Air Act is one of the most important environmental advancements of the 20th century”). Consider who is expressing the opinion – is it a source with expertise in the matter that is being discussed? Are there any sources that can be used to back up the statement? Also, look for words like “some people think” or “experts suggest” to clue you into the fact that the statement is likely not a fact-based statement.
