Final answer:
Semicolons in a list are used when the items contain additional commas or complex structures within them. In the list provided, semicolons are not needed as each item is simply a city name without further internal punctuation. However, should the cities include additional details, like countries or states, semicolons would then be required.
Step-by-step explanation:
The question at hand requires us to identify which list of places should use semicolons instead of commas to separate the items. Semicolons are typically used in lists when the items are longer and include internal punctuation such as commas within the elements themselves. An example would be 'Recent sites of the Summer Olympic Games include Beijing, China; Athens, Greece; Sydney Australia; and Atlanta, Georgia'.
The semicolons are used here to separate the larger elements of the list, each of which contains a city and country, while the commas are used to separate the city and country within each element. None of the options given (a) Paris, London, Berlin (b) New York, Chicago, Los Angeles (c) Rome; Madrid; Athens (d) Sydney, Tokyo, Beijing require semicolons because the cities listed do not contain additional commas that would necessitate the use of semicolons for clarity.
However, in the context of providing additional information, such as countries or states, semicolons would be appropriate.
