A. Negative remarks: Negative remarks in a headline can actually make it sound less credible because they may introduce bias or create a sensationalized tone, which can undermine the credibility of the information presented.
B. Formal language: Using formal language in a headline can contribute to its credibility. Formal language often conveys professionalism and seriousness, which can make the headline appear more trustworthy and reliable.
C. Someone's name: Including someone's name in a headline can add credibility, especially if the person mentioned is an authoritative figure or an expert in the subject matter being discussed. It can indicate that the information is based on reliable sources or expert opinions.
D. Slang terms: Using slang terms in a headline can detract from its credibility. Slang may come across as unprofessional or casual, potentially diminishing the seriousness of the information being presented.
In summary, to make a headline sound credible, it is important to use formal language, avoid negative remarks, and consider including the name of a reputable individual if relevant. Avoiding slang terms can also help maintain the credibility of the headline.
