Question

Which of the following options uses proper punctuation?

1) I saw a duck-billed platypus at the city-zoo.
2) I saw a duck billed platypus at the city zoo.
3) I saw a duck-billed platypus at the city zoo.
4) I saw a duck billed platypus at the city-zoo.

Answer 1

The proper punctuation option is number 2: 'I saw a duck billed platypus at the city zoo.'

Step-by-step explanation:

The proper punctuation option is number 2: I saw a duck billed platypus at the city zoo. In this option, the words 'duck' and 'billed' are not connected with a hyphen, since they are not functioning as a compound adjective. Additionally, the words 'city' and 'zoo' are not connected with a hyphen, since they are not forming a compound noun. The other options either use hyphens incorrectly or omit hyphens where they are needed.
