Final answer:
An 8oz classic coffee drink generally contains no espresso shots. In espresso-based drinks, typically one shot is used for small (8oz), two for medium (12-16oz), and three for large (20-24oz) sizes. Soft drinks are measured by volume rather than 'shots'.
Step-by-step explanation:
The number of shots that go into a classic drink can vary depending on the size of the drink. For instance, an 8oz coffee is typically one cup of coffee and does not include 'shots' in the traditional sense as used in espresso-based drinks. A shot of espresso is about 1 oz. Therefore, in an 8oz cup of coffee, there would be no espresso shots, just 8oz of brewed coffee. However, if we are considering a coffee drink that includes espresso shots, such as a latte or an Americano, conventionally one shot is added to a small size (8oz), two shots to a medium size (12-16oz), and three shots to a large size (20-24oz).
On the other hand, when looking at soft drinks like Coca-Cola or Pepsi, the measurements concern the total volume of the drink rather than the number of 'shots' since these are not prepared using shots. A small cola can typically be 12 oz, medium might be between 16-20 oz, and a large could be 24 oz or more, based on the serving size of a particular establishment or manufacturer's packaging.
