Here's why:
* It's a broad statement: It claims that *all* shoes are brown, which is obviously not true.
* It lacks specificity: It doesn't specify which shoes or how many shoes are brown.
To make the statement more accurate, you would need to be more specific:
* "These shoes are brown." (Specific shoes)
* "Most shoes are brown." (Statistical claim)
* "Some shoes are brown." (Partial truth)
