Why shouldn't you use a global variable?

Answer :

Final answer:

A global rule is a general rule that may not be appropriate in all situations. Global rules lack context, may not provide sufficient evidence, and may not apply to changing circumstances.

Explanation:

In the context of the question, the term 'global rule' refers to a general or universal rule that is applied without considering specific circumstances or contexts. While global rules can provide a general framework, they may not always be appropriate or effective in all situations. Here are three reasons why you shouldn't use a global rule:

  1. Lack of Context: Global rules often overlook the specific details and nuances of a situation. For example, in language, the rule against flipping letters is a local law because it considers the larger context of words and sentences. If we only look at individual letters, we may miss other errors, like misspelled words or incorrect grammar.
  2. Inadequate Evidence: Global rules may not provide sufficient evidence to support a standpoint or argument. In the case of global warming and the green industry, simply attacking businesses selling eco-friendly products without offering examples of the rhetoric and resulting businesses would not be a valid argument.
  3. Changing Circumstances: Rules and standards are not fixed and can change over time. What may be considered correct or effective today may not apply in the future. It's important to adapt and consider the specific situation and changing circumstances.
