Question

click to fix any plural or possessive errors below. if there is no error, just click \submit answer.\ sheldon plankton saw three feathers under his parrots cage.

Explanation:

The word "feather's" is incorrect here. Since we are talking about three feathers (plural), we need to use the plural form "feathers" without the apostrophe (as it's not a possessive in this context). The "parrot's" is correct as it shows possession (the cage belongs to the parrot). So we correct "feather's" to "feathers".

Answer:

Sheldon Plankton saw three feathers under his parrot's cage.
