Answer:
The only invalid way to earn money on micro workers platforms is by submitting an article copied from the internet, as this is plagiarism and is unethical.
Step-by-step explanation:
The valid ways to earn money on micro workers platforms include tasks that require original content and effort, such as submitting a unique article, submitting a well-written article, or complying with the number of words requested for the article. However, submitting an article copied from the internet is not a valid way to earn money as it constitutes plagiarism. This practice is unethical and can lead to consequences such as account suspension or legal action. Earning money online through legitimate means involves providing original content, valuable services, or unique skills, similar to how traditional jobs require a competitive edge to stand out.
