Bonjour, voici un exercice avec lequel j'ai du mal - Underline the forms of passive voice in the text. In 1886, Dr John S. Pemberton, a pharmacist from Atlanta, Georgia, invented a new type of syrup, using cocoa leaves, sugar and cola nuts, plus a few other secret ingredients to sell as a medicine for headaches and tiredness. As he was unsuccessful, he sold his secret formula to another pharmacist who mixed up the syrup with soda. In 1903, the secret formula for Coca-Cola eliminated cocaine as one of the ingredients and replaced it with caffeine. In 1895, the drink was put into bottles, so customers could enjoy it anywhere. To avoid imitations, by competitors, Coca Cola was put into special bottles in 1916. The contoured bottles were trademarked in 1977 and are the same bottles that we still see nowadays. According to most Internet sources, the Coca-Cola bottle is one of the most recognised packages on the planet. Throughout the years, the slogans used in advertising for Coca-Cola have reflected not only the brand, but the times. They have had a considerable impact on American culture and the brand has a high degree of identification with the US. Coca-Cola logo is the most famous commercial logo in the world which has not changed in more than 100 years. The first year when Coca-Cola started to be served, sales averaged nine servings per day in Atlanta. Today, daily servings of Coca-Cola beverages are estimated at 1.9 billion globally.
