Answer 2

Answer:

These knives are very sharp.

Explanation:

When a noun ends with 'f' or 'fe', the 'f' or 'fe' is usually substituted with "ve" before putting the 's' to make it plural.

Example:

1. shelf = shelves
2. wife = wives
3. knife = knives
4. wolf = wolves
5. self = selves

For the plural of 'knife', we remove 'fe' and substitute it with 'ves'.

These knives are very sharp.
