Logos is persuading by use of reasoning. In this picture logos is showed in the message, it is giving a reason of why smoking is bad, because it gets people hooked and smokers smoke over five thousands cigarettes a year.
Text Example Logos is also presented in the article, "The Challenge of Food Waste", the authors talk about how the grocery retailer, SuperValu, has donated 22,000 tonnes of food in the year of 2010, which produced 37.5 million meals. That fed many less fortunate Americans. This is an example of logos because the authors are giving reasons as to why donating food can help everyone. The less fortunate by feeding them and the ones donating, by helping do a good deed.
