A list punctuation question tests how you separate items with descriptions. First, find where each item ends, keeping each name with its description. Then check how the parts connect: commas separate simple items, while semicolons separate items containing commas. A colon follows a complete sentence to introduce a list or explanation; a dash sets off a break or added detail. Use those roles to tell marks within an item from marks between items.
Hints
- Hint 1
Read the track names together with their descriptions. Where does the product design item end, and where does the marketing strategy item begin?
- Hint 2
Check the punctuation already used in the list. What job does each mark do?
Step-by-step
Follow the list’s pattern
Step 1Find the item’s end
After offers three tracks:, the sentence lists data science, product design, and marketing strategy. Where does the blank fall in that list? The which centers on user research and part still describes product design, while and marketing strategy begins the next track. We're choosing punctuation for the end of the product design item, so its whole description must stay together before the next track begins.
- Step 2
Read the existing separator
How does the sentence separate one whole track from the next? In experienced analysts; product design, a semicolon closes the data science item, including its description. The comma in data science, which marks where that track’s description begins, and product design and marketing strategy have the same kind of comma. Each item contains a comma, so semicolons show where the whole items end without mixing those ends with the commas inside.
- Step 3
Use the matching separator
Would a colon or dash work at this break? Either would treat and marketing strategy as an explanation or added detail after product design, rather than the next track in the same list. A comma would use the same mark between tracks as between each track’s name and description. The version with a semicolon after prototyping matches the list’s existing separator and closes the product design item before marketing strategy begins. Choice B.
